Benefits of Introducing Optical Caliper Sensor
Motonori Tahara
Paper and Web Solution Dept., Yokogawa Electric Corporation
Caliper measurement is unique from others in the sense that it pinches the paper web between the sensing planes for the measurement
purpose although a paper quality control system is associated with various measurement functions. This has often become the issues in paper
production process making holes and marks by sensing plane touching the paper. In order to solve these issues, non-contacting caliper sensors
has been introduced applying measurement principles such as laser measurement. However, these sensors are yet to be utilized for thecontinuous measurement and control of production lines because they still have some essential technical issues have to be solved.
In such background, Yokogawa Electric Corporation started the development of Optical Caliper Sensor applying the confocal technology and achromatic aberration for the measurement principle of the sensor. Since the Optical Caliper has actually been tested on line at one of paper
mills in Japan during January 2008, increasing the number of customers has approved this sensor as the solution to solve their issues. Currently
in Japan, all the Optical Caliper installed in Newsprint and White board Machines are utilized for the caliper profile control and have achieved
zero-holes, zero-marking and zero-curl related sheet brake.
This paper introduces starting with the history of the caliper sensor, explains the measurement principle and tuning method of the Optical
Caliper Sensor, and finalizing with the benefits of introducing this sensor in Newsprint and White Board applications.

Takashi Hatogai
Engineering dept., SHIRATORI Engineering Co., Ltd.
The Paper & Pulp Industry is obviously one of the most energy consuming one among all of the industries. It has been pursuing both recyclingof waste paper and utilizing natural resources in various aspects. Especially, “How to save energy efficiently” is a vital target because of therecent rise of material cost and crude oil price.
Above all, energy consumption in dryer part in the paper production machine is the most focused whose consumption rate occupies more thanhalf of the total energy consumed. Every paper manufacturing company is repeating its full efforts so that energy consumption rate may beminimized. Also they are pursuing longer life-time of their facilities as well as higher efficiency of maintenance and improvement of theirenvironmental condition. Under such tendency, upsizing of machines with higher speed for wide papers has been widely promoted. Also, itsometimes required remolding of facilities such as hood system and ventilation equipment for reinforcement.
We, Shiratori Engineering, who has cultivated lots of technologies and know-how, have sufficient delivery experiences of the hood system tovarious customers. We herewith would like to explain the essence of “High Dew point type of Totally Enclosed Hood System and Relative
Equipments”.

Technological Transition of Quality Control System
Tomohiro Mineo
Paper and Web Solution Dept., Yokogawa Electric Corporation
QCS(Quality Control System) was developed in the end of 1960s, and it had come into wide use in Japan during 1970s through 1980s.
Although QCS has started as a mere measuring instrument, its first installation has drastically changed the works related to the paper
production. Therefore, in some cases, people even refers to QCS as, “The instrument that has altered the paper manufacturing procedure.”
QCS has now become an indispensable system for manufacturing the paper in the modern days of paper production.
This report introduces technological transition of QCS focusing on recent 30 years after it has come into wide use, and also mentions on theorigin and foresight of this equipment.

Outline of the Tomakomai Mill Hydropower Station
Luning Zhang
Tomakomai Mill, Oji paper Co., Ltd.
Oji paper Tomakomai mill has nine hydropower stations in Hokkaido. Five of them are located in Chitose, two of them in Eniwa and other twoof them in Niseko. The oldest one, Chitose No.1 power station was built as a power source of the Tomakomai mill in 1910. With expansion of
the mill, other four power stations were added in downstream, in 1916 to 1941.
Even now these power plants are still working for power supply to the Tomakomai mill by executing careful maintenance. However, the plants
have been deteriorating because they have been operated for 70-100 years. In order to intensify power generation business and contribute to
low carbon society, Oji paper will refresh those hydropower stations in coming years.
The refresh construction includes renewal of control drive unit, inlet-valve, guide-vane and runner. In this report, we introduce outline of eachpower station and brief overview of the refresh construction.

A Summary and Operating Experience of Biomass Incinerator Plant

Daisuke Ishimura
Tonegawa Division, Rengo Co., Ltd.
With the aim of reducing CO2, saving energy and preserving the environment, we installed a biomass incineration plant within the Tonegawa
Division in 2012.
At the former rotary kiln incinerator plant, waste heat from incinerating industrial wastes was not recovered and energy was not usedefficiently. However, at the biomass incineration plant, energy is recovered by steam. This has allowed fuel (LNG) for boilers used as in-house
power generators to be reduced and CO2 emissions to be cut significantly. After starting the operation of the biomass incineration plant, thevolume of fly ash and bottom ash has increased, but total volume of industrial wastes has been reduced.
We intend to work hard to see to the safe operation of the plant.

Technology Development of Bioethanol Production from Woody Biomass
Atsushi Furujyo
Bioethanol Research Section, Oji Paper Co., Ltd.
Bioethanol produced from biomass is expected to become a sustainable energy source in the future since bioethanol has advantages over fossil
fuels. Namely, bioethanol is a natural and renewable form of energy that does not increase atmospheric carbon dioxide levels, because burning
biomass releases carbon dioxide that is largely balanced by the carbon dioxide absorbed in its own growth. In Brazil and the United States,
bioethanol produced from sugarcane, corn and other crops is already being used as automobile fuel by blending with gasoline. Increase inbioethanol production may, however, leads to increase in food prices due to the competition with food production. For this reason, research on
cellulosic bioethanol is being conducted, mainly in Europe and the United States, with the objective of realizing its production.
We report herein our company’s research on development of bioethanol production technology with the combination of a mechanochemical
pulping pretreatment technology, a simultaneous saccharification and fermentation technology using own heat tolerant yeast and an enzyme
recycling technology, in which woody biomass (e.g., fast-growing trees and forestry residues) is used as a raw material to obviate competition
with food production.

Development of Methane Fermentation Technology for Wastewater Treatment-Investigation of Method to Prevent Flocculated Methanogens from Becoming Smaller by Addition of Starchy WastewaterIsao Onodera
NPI Research Lab., Nippon Paper Industries Co., Ltd.
Lately methane fermentation technology is widely applied in many industries because of the recent development in this technology has madewastewater treatment highly effective. One of the advantages of this technology is to recover energy as biogas from organic compounds in
wastewater. This paper describes application of methane fermentation technology to KP mill evaporate condensate at Nippon Paper’s two KP(kraft pulp) mills, the Yufutsu plant of Hokkaido mill and Iwakuni mill. Through the experience in actual operation of methane fermentation, it
was recognized that there was a problem of overflowing granule from the reactor caused by upward flow in the reactor.
In order to look into the problem, we compared the properties of granule in Yufutsu plant with those in food mill which already established astable process in methane fermentation treatment. As a result, filamentous acetic acid-degrading methanogens (Methanosaeta) was mainly
observed in food mill’s granule, while spherical methanol-degrading methanogens (Metanosarsina) was mainly observed in Yufutsu plant’s
granule. This difference of methanogen species, which was caused by methanol treatment, is presumed to weaken the cohesive force of granule,consequently making the granule remarkably fine. On the basis of the result of this investigation, we studied of method to prevent flocculated
methanogens from becoming smaller by lab.-experiment. It was found that the addition of starchy wastewater was very effective. Trial atcommercial plant showed that the addition of starchy wastewater increased Methanosaeta and granule became bigger and heavier.

Chen Jun and Masahito Mukai
Paper Machinery Engineering Dept., Kobayashi Engineering Works, Ltd.
Although the growth rate has become slow down recently, Chinese paper industry still keeps higher level of its expansion. Our company
continues supplying formers from the beginning of 1980, and we take pride in having supported the growth of industry. The occurrence which
has deeply recognized us, is a remarkable progress of Lee & Man Paper Manufacturing Ltd. which acquired the 2nd place of paper andpaperboard production in China. It was only a 100,000-ton /year with two paper machines until 1999, however, it has become the production
capacity of 30 times or more in about ten years. The opportunity of employing the first Success Former for PM3 in 2000, may have become alandmark for the subsequent progress of Lee & Man Paper. Success Former features both high quality and productivity with excellent energy
saving former operation. The results are four continuous repeat orders for PM5, PM10, PM11 and PM13, respectively. The forming sections of
all above machine consist of three-ply Success Formers with sheet transfer felt systems.

The New Internal Sizing Agent for Paperboard as an Alternative to Rosin Materials
Junichi Hogouri
Research and Development Department, Paper Chemicals Division,
Arakawa Chemical Industries, Ltd.
In recent paperboard manufacturing, recycled paper is used as the main raw material. The recycled material involves deteriorated fiber andmuch filler such as calcium carbonate (CaCO3). Higher CaCO3 content in pulp slurry will increase pH, therefore acid additives such as alum
will be neutralized and easily lose their ability. To make matter worse, Paper manufacturers will tend to avoid the addition of acidic
compounds. Higher pH condition and lower addition level of Alum causes lower sizing degree, in particular the case of rosin size.
In neutral-alkaline papermaking condition, AKD or ASA is commonly used instead of rosin-Alum system. However, in the case of paperboard,slow speed in inducing sizing of AKD, paper slipperiness trouble, and deposit or poor machine runability trouble on ASA will be recognized. In
this report, a new type sizing agent will be introduced. It must cover wide range pH of wet-end condition and can be possible to replace rosinAlum system.

Due to their low specific gravity, porous fillers, including precipitating silica, have, in recent years, been increasingly used as additives (fillers)
for the purpose of increasing paper bulkiness (reducing weight). The use of porous fillers has advantages such as continued utilization ofexisting equipment without the occurrence of discoloration problems inherent with mechanical pulps. However, problems such as degradedpaper strength still remain to be solved. In view of this, we have conducted a study in an attempt to develop a high quality porous filler withsuperior bulkiness performance, excellent opacity and minimal degradation in paper strength.
This report reveals that a porous filler with minimized degradation in paper strength, high bulkiness performance, and excellent opacity has
been obtained by optimizing the primary particle diameter and the secondary coagulation particle diameter.

Main Features and Field Cases of Color Surface Inspection System （MaxEye.Color）
Masahiro Suzuki
FUTEC Inc.

A sheet surface inspection system, equipped with the monochrome line scan cameras, uses inspection object’s contrast and shape data for
defect classification. Therefore it makes difficult to classify the defects by color. Another reason for the difficulty of defect classification by color
is that the conventional color line scan camera (drive frequency: 40MHz) is not capable of having enough MD resolution for clear image.
Now, FUTEC has developed a new surface color inspection system, “MaxEye.Color”, using high-speed color line scan camera technology witha drive frequency of 80MHz. Three main features of this system are: (1) a clear color image of defect, (2) an intuitive color defect classification
setting, (3) a real-time color defect classification .
This system enables operators to see sharp, clear color view of defects to determine the cause of defects in early stage of production.
Furthermore, it carries out the automatic defect classification for color defects only by using real time processing function. This function
contributes to the operation efficiency by supporting operators' checking process.

Simple Environmental Water Quality Analyzer
Kiyoshi Ogawa
Sales Planning Dept., DKK-TOA CORPORATIONThe environmental law regulates the upper limits of the concentrations of harmful substances in the discharge water. Every facilities will be
imposed the penalties based on the law if depart from these standards, and also causes adverse impact to corporate image. To avoid these risks,
continuous monitoring of the drainage is desired. The analysis of high accuracy is often time consuming. In order to take quick measures to theleakage of hazardous components, rapid detection of leakage is required. To prevent the leakage of hazardous components, rapid detection
should take precedence over accuracy.
Simple and rapid water quality analyzers are used in many facilities. Some of them judge only ON-OFF of hazardous components in thesample. But many of them are able to obtain good correlation to legal method. Some examples of simple and rapid water quality monitoring
instruments are shown below.

Development of On-Line Moisture Sensor System
Shinichi Nagata and Hidetada Sawamoto
Technological Initiatives Research Laboratory,Oji Holdings Corporation
In recent years, the paper or film products with new functionalities have been developed increasingly. We also have been developing new
products with several functionalities. In the coating process, especially water-based coating, the control of moisture content after drying is very
important to improve the product quality. At the beginning, we also introduced a moisture analyzer of infrared type to measure the little
moisture content in the coated product. But it was found that the infrared type was not suitable for measuring the little moisture content
because it was affected by the around heat source or the base materials' absorption and was not stable over a long period. So we started todevelop the moisture sensor system by ourselves. Through trial and error, a new on-line moisture sensor system has been developed. The
measurement principle is based on the dielectric loss of the water which is very large compared with those of other materials. We introduced theoriginal microwave resonator to detect the dielectric loss of the water in the products. This sensor system is now necessary for producing thecommercialized coated products in our mill.

Biodiversity Initiatives at Nippon Paper Group
Keiko Watanabe
Nippon Paper Industries Co., Ltd.
Nippon Paper Group is a corporation closely connected with biodiversity. We utilizes trees， a renewable resource provided from ecosystemservices， to provide society with products such as building materials， paper and chemical products and support people’s lives and contributeto cultural development. The loss of forests would lead to a loss of our operating base. Continuing the stable supply of products that utilize
forest resources by taking into account biodiversity and pursuing sustainable forest management is one of the Group’s social responsibilities.
For this reason， we have established “helping preserve the global environment over the long term and contributing to the development of arecycling-based society by carrying out corporate activities in recognition of the importance of biodiversity”as the philosophy of our Charter on
the Environment and undertaken a variety of initiatives in this area.
This report focuses on the activities undertaken by Nippon Paper Group， whose operating base is forest resources， to ensure the continuityof its business. The report will introduce activities the Group has undertaken to preserve biodiversity from the dual perspectives of “initiatives
through core business activities” and “initiatives utilizing in-house resources and technologies.”

Application of Cellulose：Manufacturing Stronger and Lighter Bioplastic Combined Cellulose with Plastics

Chuetsu Pulp & Paper Co., Ltd.
Wataru Mizuno
Toyama Industrial Technology Center
In recent years, because of increasing of interest in development of the low-carbon society, many researchers are studying to replace frompetroleum-derived materials to eco-efficient plant derived “green” composites materials . Natural wood is the most sustainable and renewable
resource and stockpile of natural wood on the earth will reach a trillion tons. Pulp mill has been living with the production and sale of pulp andpaper as core business by using these natural woods.
Pulp is mainly consisted from cellulose fibers that have several ten micrometers diameter, the unit element in the fibers composition iscellulose (nano)fibrils that possess diameter ranging 1 to 100 nanometers with a high aspect ratios. These fibrils can be easliy dispersed in waterby chemical modification (surface oxidation, acidic hydrolysis) or high pressure shearing, and the dispersed nanofibrils are called cellulose
nanofibers (CNF).
We have produced various cellulose nanofibers from our own pulps and studied the composites containing CNF and polypropyrene (PP). As aresult, it was confirmed that improvement of the mechanical properties by blending a few percent of CNF to PP resin. In addition, Interestingly,
depending on the degree of fibrillation level of CNF, the composites were shown different mechanical properties for each. Improvement effectof CNF-composites shows a tendency to decrease in composite materials with CNF which has been too progressed fibrillation. Therefore, it wassuggested that the optimum fibrillation-level of CNF for improvement of mechanical properties of composites might exist.

Operating Experience of Hyper-Cell Floatator
Hisashi Iwabuchi
Hokkaido Mill-Yufutsu, Nippon Paper Industries Co., Ltd.

In Japan, the utilization rate of recovered paper reached 63% in 2009. Except paper board, ONP is mainly used for recovered paper. Since
news paper quality, such as ash content, has been changed, ash and microsticky removal is required, especially at the flotation process for paper
recycle. In order to improve DIP quality and promote further use of DIP, AIKAWA Iron Works Co., LTD. and Nippon Paper Industries
developed the state-of-the-art floatator “Hyper-Cell Floatator” and installed in Hokkaido Mill-Yufutsu in 2008. This report introduces ouroperating experience of Hyper-Cell Floatator.

Efficient Use of the Residue of Bio-Fuel Production-Paper Production from Sweet SorghumAtsushi Ohno and Shinichi Hara

The College of Agriculture ，Ibaraki University
When we get lack of energy, as the energy demand grows, there comes the time to research biomass energy. But the enthusiastic researches
fade away, sooner the oil price gets down to be stable. It has been 20 years since they started research sweet sorghum as a bio-fuel at Ibaraki
University. To make bio-fuel, sugar is extracted from sweet sorghum and fermented to be ethanol. They actually made success to run
automobiles with the bio-fuel. It is a great progress. Here we suggest another point of view for sweet sorghum, to make pulp from the residue ofbio-fuel. There remains a lot of cellulose after sugar extraction in the sweet sorghum. We found that it is possible to make pulp from the residueof sweet sorghum, and furthermore the strength of pulp is stronger than that of LBKP. We finally produced envelopes available for general use,enhanced the value to the residue of bio-fuel. Since it is true that it costs a lot to make pulp from the residue, reduction of pulping cost is thefirst problem to solve. Anyway, it is significant to contribute to study the biomass, not only for bio-fuel but for the residue to reduce waste or
costs.

Energy Saving Strategy with Steam-Driven Compressor
Toru Mizutani
Tokai Mill, Oji F-Tex Co., Ltd.
At the Tokai mill of Oji F-Tex Co., Ltd, the steam generated by boilers is adjusted through reducing valves to a required pressure and supplied
to each equipment. Although one of the ways to utilize the differential pressure is to generate electric power using a steam turbine, the Tokai
mill does not adopt this kind of system because its differential pressure and steam consumption are not so high.
Meanwhile, a steam-driven compressor has been introduced to the Iwabuchi and Fujinomiya manufacturing sites. One of the reasons for
adopting the compressor is that paper machines use a lot of compressed air.
The steam-driven compressor is operating smoothly, and therefore allows some electric compressors to be on standby. It has led to reducing
both energy consumption and frequency of maintenance on the electric compressors.
This paper describes the introduction effects of the steam-driven compressor.

#5 Paper Machine Dryer: Energy Saving Introducing High Dew Point Enclosed Hood System
Zenji Motoyoshi
Edogawa Mill ,Oji Materia Co. ,Ltd.
Oji Materia Co., Ltd. Edogawa Mill is only one white board paper production plant in Tokyo metropolitan area that is located in the easternend of this capital city. This plant has significant geographical advantages. It can be easily gathered abundant of waste paper and is also very
close to the vast market. Miura Co., Ltd.
The Edogawa Mill is running to produce white board paper with company’s theme of “Living together with people & local communities there”.
In this plant, #5 paper machine has started full production in May 1971 as specialized making white board paper. Current production isabout130000 tons per year and the products are mainly delivered to the paper container industries.
The dryer part out of the whole paper production process is the most energy consuming section and considered it most effective for energy
saving if it can be modified appropriately. However, such modification work for the dryer part including hood system had not been realized in
the past due to possibly vast investment.

Now, we have carried out renewal of both the dryer hood and the air supply/exhaust equipment which has enabled to achieve the saving ofsteam and electricity. We would like to hereby explain an outline of the modification of the dryer hood system and also describe how energy
saving effects was attained with it.

Efficacy of Energy Saving Project in Niigata Mill, Hokuetsu Kishu Paper Co,,Ltd.
Minoru Sakaue
Niigata Mill, Hokuetsu Kishu Paper Co., Ltd.
Recent years, the global warming is the one of the biggest issue for us. Especially, reducing carbon dioxide emissions which are well known as agreenhouse gas is our main concern. Because of these movements, we need to expedite both the reducing fossil fuel consumption and the saving
other energy consumptions at the same time. In order to approach these issues, we have started the energy saving program at Niigata mill since
1980’s and these works have brought great success. However, after we installed the new paper making machine PM9 and converted the otherrelated processes such as the pulping, the bleaching and the chemical recovery facilities, the energy consumption surged and that cost put
pressure on our profit.
In this report, we introduce the energy saving program at the Niigata mill and give the detail of our achievements after we installed andconverted the new processes.

An Operating Experience of Partial Borate Autocausticizing
Tomofumi Kogawa
Technical group, Technical department, Hachinohe mill, Mitsubishi Paper Mills Limited
Partial borate autocausticizing (AC) is the patented technology from U. S. Borax Inc. which partially replaces lime causticizing with borate
AC. In Hachinohe mill, we conducted partial borate AC by adding borate to recovery cycle from March 2010 until March 2011.
The AC level reached up to 10%. Partial borate AC made it possible to increase white liquor (WL) production without any equipment
investments. The amounts of burnt lime and heavy oil required for producing every tons of WL were both decreased.
The cost of WL produced by borate AC was lower than the case which purchased lime was used for WL production.

Application of Biomarker Technologies for Afforestation
Nobuyuki Nishikubo
Forest Technology Laboratories, Research & Development Division, Oji Holdings CorporationOji paper have been expanding the oversea plantation area to 240,000 ha until 2012. These logged trees are utilizing to make lumber, plywood
and wood chips. The selection of the appropriate tree to each plantation environment is required, because it is different weather and soil
conditions between each plantation. The selected excellent trees propagate by cutting and plant as clonal plantation. Therefore restrict
conservation of these selected trees are important for future production, wood quality and yield ratio of lumber.
To control production and quality, we developed identification method with SNP biomarkers. Using the SNP marker in E. pellita clonal trial
and clone bank, we successfully identified and rearranged for more than 100 kinds of clones.

The Classification and Kind of Paperboard
Akihiro Yamamori and Taku Uchiumi
Oji Materia Co. ,Ltd.
The paper and pulp industry has mainly developed at the area of printing paper. The paperboard and high performance papers have been
focused in recent years due to industrial structure change.
The production of the paper and paperboard fell off sharply after Lehman Shock in 2009 and has remained lower level in Japan. The
consumption of printing paper has been decreasing year after year due to emerging of new digital device and depression. However, theconsumption of paperboard has shown stable growth.

On the other hand, the production of the paper and paperboard in the world keeps higher growth rates because of economic growth of China,
India and other Southeast Asia. The presence of the paperboard has been increasing in the paper and pulp industry.
We will describe the outline about the paperboard.

Molding of the Category of High Performance Papers-The Technological Locus of High Performance Paper SocietyYoshinari Kobayashi
Kagawa Prefectural Industrial Technology CenterIn 1962 “High Performance Paper Society” was initially found as the name of “Chemical Fiber Paper Society” by researchers of Shikoku
National Industrial Research Institute and Prefectural Paper Industry Technology Centers in Shikoku with challenging the targets of making
paper from rayon and synthetic fibers. In 1982, with shift of industrial requirement the purpose of the Society was revised to research thescience and technology for making papers by wet-laid from almost all kinds of short fibers, that is, natural, regenerated, synthetic, inorganic andmetallic fibers. This meant enlarging the definition of paper. Reflecting on the 50 year history of the Society, the category of high performance
papers was safely said to have been established for core industries in parallel with that of general use paper from plant fibers. The main
accumulated technologies for high performance papers were chronologically overviewed by dividing decade years.

Report on the Results of the Fiscal 2012 Follow-up Survey on JPA's Committed Action Plan and Efforts against Global Warming in theJapanese Pulp and Paper Industry
Naoki Ikeda
Japan Paper Association
The Japan Paper Association (JPA) has been actively working to save energy since 1997 when it established its “Committed Action Plan on
Environment”. JPA declares its policy of restraining CO2 emissions in the action plan, and is working toward the following targets revised in
September 2007:･ On a ﬁve-year average basis from ﬁscal 2008 to ﬁscal 2012, reduce fossil energy consumption per ton of production and fossil energy derived
CO2 emission per ton of production by 20% and 16% from the level of fiscal 1990, respectively･ By ﬁscal 2012, expand forest plantation area owned or managed by the industry at home and abroad to 700 thousand hectares.
Since fiscal year 1990, JPA has made a survey on the actual results of energy consumption in the year, and published its results compared withthat in fiscal year 1990. This report shows the results for fiscal year 2011.
According to the fiscal 2012 survey, pulp and paper industry's fossil energy consumption per ton of paper production and f in fiscal 2011 was
25.4% lower than the level of fiscal 1990, which is almost the same level as previous year. This is mainly thanks to manufacturers’ continuous
energy saving efforts and improved production efficiency through restructuring their production system, in spite of a significantly decreased
production.
On the other hand fossil energy derived CO2 emission per ton of production was 20.1% lower than the level of fiscal 1990, a 2.6 points
deterioration compared to the level of fiscal 2010, due to an increased in-house power generation to address electricity shortage caused by theGreat East Japan Earthquake and change in fuel mix with production shift to unaffected mills from large mills damaged by the disaster.
In addition to the results of the follow-up survey, this report introduces the position of the pulp and paper industry in national energy
consumption and CO2 emissions, and information such as JPA's Action Plan for low-carbon society and the impact of the raise in electricity
prices on the industry.

Due to their low specific gravity, porous fillers such as synthetic silica are being increasingly used as an additive to increase paper bulkiness.
The use of porous fillers has advantages such as continued utilization of existing equipment with no requirement for the installation of new
equipment such as a shoe calender. Porous fillers also prevent the discoloration problems inherent with mechanical pulps and the soiling of thepaper machine that occurs with the use of a fatty acid derivative or special surface-activate agent as a bulking agent. However, there are still
outstanding issues such as degraded paper strength, although the level of degradation is lower than with other paper-bulking techniquescurrently being applied. In view of this, we conducted a study in an attempt to develop a high-quality porous filler with superior bulkinessperformance, excellent opacity and minimal degradation in paper strength. In the first report, we revealed that a porous filler with minimized
degradation in paper strength, high bulkiness performance, and excellent opacity had been developed by optimizing the primary particle
diameter and the secondary coagulation particle diameter.
This report reveals that a porous filler with minimized degradation in paper strength, high bulkiness performance, and excellent opacity wasdeveloped which uses alkaline-resistantmicroparticles during the reaction. This enables control of primary particle diameter, secondary coagulation particle diameter, and particle size
distribution.

Integrated Solution for Resource Management and Cost Reduction in Fiber Lines
Dinesh C. Mohta Ph.D.
Nalco Company, Asia Pacific Marketing
Shintaro Sato
Marketing , Katayama Nalco Incorporated
In Japan, pulp production cost is one of the highest in the world mainly due to ever increasing cost of the imported wood chips. Given thevariations in wood maturity and subsequent chips quality, it is always a challenging task to maintain smooth operations in the pulp mills. Henceto minimize this effect, it is necessary that more attention is given to cooking and washing operations for an optimal runnability of the fiberlines. The optimization of digester and brown stock washing operations will bring substantial improvements in bleaching and evaporator plants'
operations together with higher pulp quality. As part of the digester optimization, the use of PenSurf Technology offers great benefits ofimproved production and in reducing and overall total cost of operations.
Further to minimize water borne issues, it is necessary to take the right steps to avoid scale formation in pipe lines and equipment particularlyin the bleach plants. The drainage aid for the lime mud dewatering offers great advantages in not only increasing dry solids but also in
minimizing the energy cost.
In addition to the process optimization, implementation of an integrated solution for specialty chemical management will not only achieve
desired synergy for improved plant runnability and pulp quality but also set a new example of efficient resources (fiber, water and energy)
management in pulp mills lower production cost and better environmental sustainability.

System Upgrade for Stock Preparation and Approach Flow
Masamori Tanaka
Paper Machine Eng. Dept., Voith IHI Paper Technology Co., Ltd.

Fiber recovery system is one of the most important parts not only for approach flow but also for all of paper making system. To recover fibers
can gain better yield, and to make clearer filtrate helps reducing specific water consumption. Moreover, if the consistency of white water isdecreased by Fiber recovery system, it saves the consumption of power and chemicals, and also size and number of machines in water treatment
system dramatically. DiscfilterTM helps this solution with state-of-the-art technology as BaglessTM sectors and Filtrate valve. C-bar F basket isanother solution which has less installation cost. These technologies will supply much more benefit for the environmental-related future.

New Board Machine Concept
Yoshiki Kabutoya
Engineering Division , Metso Paper Japan Co., Ltd.
The global containerboard production is moving toward lighter basis weights [1]. While the basis weights have decreased, the use of recycled
fiber as containerboard furnish has increased. This is especially so in Europe where strong testliner is made primarily from old corrugatedcontainers (OCC) and other recovered paper grades.
The trend towards a more lightweight containerboard and a higher OCC content has opened the doors for high machine speeds through theuse of a gap forming concept. Metso has utilized the long and extensive experience of efficient, fast-running paper machines when building fast
containerboard machines.
Following machines are introduced in this paper.

Formulations for High Speed Coated Inkjet Paper

Within a global market for printing and writing that is at best flat, consumption of paper for coated reel-fed (high speed) inkjet is growing.
Growth is driven by the potential to print on demand, reducing the need for high inventory of printed material and making it possible topersonalise the content. The rate of growth and ultimate target market size is widely debated by analysts and commentators, with the key
difference being whether coated inkjet can also take market share in coated magazines from traditional offset printed grades.
One of the most significant hurdles to delivering mass commercialisation of coated inkjet paper for magazines is the availability of a costeffective paper substrate in a range of grades which has the look and feel of traditional magazine paper. This is because making good quality
inkjet-compatible coated paper is challenging. In terms of mineral components, silica or surface modified mineral pigments are typically used tocreate a suitable pore structure that enables sufficient capillarity to give fast removal of the fluid components of the ink together with large
pores to enable drainage of the ink volume. These types of mineral pigments are typically expensive compared to traditional coating pigments
and inherently require low application solids which can prevent high speed coating. Other existing solutions are based on a cationically-charged
formulation to help fix the ink close to the paper surface. This causes problems on paper machines that spend most of their time producing
under anionic conditions. As a result, the papermaker must take great caution to avoid any contamination when switching between production
runs.
IMERYS has been working to overcome these issues in order to assist the papermaker in bringing to market a formulation that could genuinely
make mass adoption of coated inkjet paper a reality. Our philosophy has been to concentrate on more traditional mineral pigment types fromour extensive portfolio of materials and grades to enable high application solids and to maintain anionic formulation chemistry, reducing thepressure on the papermaker who wants to produce in campaigns. To make this possible, it has been necessary to develop a full-formulation
understanding for this concept.
In this paper we will expand on our view of the coated inkjet market, its size and technical needs. We will introduce the techniques that wehave developed for characterising these papers and share application data of our proposed formulation concept, benchmarked against
appropriate commercial grades.

Energy Saving by Reducing Water Content of Lime Mud Filter Cakes
Hideo Yamamoto, Yasuhiro Kagawa, Takashi Saigusa and Keiji Suruga
Kurita Water Industries Ltd.
In KP caustic recycle process, a large amount of heavy oil is used as fuel of lime calcinations in the rotary kiln. Reducing the water content in
the lime mud is an effective way to reduce heat loss in the lime kiln, and save heavy oil.
This paper focused on a dewatering technology to increase the hydrophobic of the surface of CaCO3 particles by a new developed chemical. It
is found that the lime slurry temperature is an important effect on dewatering aid. A new dewatering aid is developed by optimizing thehydrophobicity and its molecular weight. The new dewatering aid achieved 10% of heavy oil saving in a machine trial.

for debris classification of the 2011 Off the Great East Japan Earthquake.

Carbon Credit Program in Alberta, Canada- Carbon Offset Credit by Portable Chipping Kazuyoshi Noguchi and Takuya Yamamoto
Daishowa-Marubeni International Ltd.
With increasing dependence of U.S. oil imports on Canada, Canadian oil sands production is growing significantly. Oil sands deposits arefound in Western Canada, mostly in Alberta.
Due to its unique nature, oil sands production requires significant amount of energy. In terms of greenhouse gas (GHG) emission, oil sands
extraction, mining and upgrading are responsible for about 40% of Alberta’s gas emission from industrial sector.
On the other hand the government of Alberta is constantly under pressure of reducing carbon foot prints throughout the province. GHG
reporting program in 2003 requires major industrial facilities to submit annual reports on their GHG emissions. In 2007, GHG reduction
program was put in effect. Alberta is the only jurisdiction in North America with mandatory GHG emission reduction targets for large emitters
across all sectors. This program promoted renewable energy developments.
In this paper, outline of carbon credits in Alberta and offset credit awarded to portable chipping operation are described.

Structure-Control of Amphoteric Polyacrylamide and Its Performance as Dry Strength Resin
Hideo Baraki
Paper Chemical Business Division, Seiko PMC Co., Ltd.
Dry strength resin is known as multifunctional chemicals to enhance paper/paperboard strength, drainage and retention. Especially,polyacrylamide (PAM) based dry strength resin is widely used in various paper/paperboard grades in Japan. Linear, Low-branched, and highbranched PAM containing both anionic and cationic groups were obtained with free radical polymerization. Molecular weight and structure of
PAM were determined by gel permeation chromatography coupled on line to a multi-angle laser light scattering detector (GPC-MALS). The
higher degree of branching, the more compact a polymer chain, which leads to decrease in the viscosity of aqueous solution.
The effects of structure and molecular weight of amphoteric PAM on the performance of dry strength resin were investigated. The highbranched PAM with higher molecular weight showed greater performance in retention of PAM and paper strength. The zeta-potential ofamphoteric PAM increased with the increasing of the degree of branching. The high-branched amphoteric PAM was able to form polyioniccomplexes in high salt concentration (electro conductivity, 650mS/m). The effective iconicity of amphoteric PAM could be controlled bychanging the structure of polymer.

An Attempt to Produce Bio-Diesel from Pulping Byproducts- In the Case of Tall OilHao Ren
Department of Light Industry & Science, NanJing Forestry University
Shigetoshi Omori
State University of New York, College of Environmental Science & Forestry
Biodiesel is generally produced from food-related materials such as vegetable oil and animal fat (tallow). The most commonly used source isvegetable oil waste; however, its supply is limited. Should there be a shortage of vegetable oil waste, biodiesel production may turn to fresh
vegetable oil as a source, with possible impacts on the food supply. Several non-food resources were investigated as prospective sources forbiodiesel production, and pulping byproducts have shown potential. Tall oil was selected as a representative byproduct typical of the pulping
process, and early trials showed that a reasonable amount of biodiesel yield was able to be produced. Initially, several issues were found which
would limit the practicality of producing biodiesel from tall oil: reaction time, reaction temperature, reduction of chemical usages, the role ofacetyl chloride, and the reduction of solvent consumption amount. Through experimentation, most of these potential issues were able to be
mitigated, supporting the very real possibility of mass producing biodiesel from pulping byproducts.

The Improvement of Boiler Efficiency on Our Pulverized Coal Fired Boiler− Introduction of Coal Additive to Control Clinker Generation to the Boiler −Kazunobu Kawaharagi
Kushiro Mill, Nippon Paper Industries Co., Ltd.
This paper presents the energy saving effect which was gotten by introducing the Fe-based coal additive to prevent Clinker generation to solve
troubles on our pulverized boiler.
Nippon Paper Industries installed the new pulverized boiler which called N1 boiler and the new steam turbine which called N1 turbine inKushiro mill in 2004, and has begun electric power wholesale business with accumulated know-how to operate pulverized boilers.
After into commercial operation, we had been suffered from the following problems on the N1 boiler.
· Huge clinker growth which is over the furnace wall bottom. And peeling off of it had made unexpected halting the boiler operation due to thebottom ash conveyor trip.
· Plugging trouble on the heating element of the Ljungstrom type air preheater caused by ash and sticky acid ammonium sulfate (NH4HSO4)
which was produced by ammonia leakage from the NOx removal reactor combined with SOx. And also the acid ammonium sulfate sticks
discharge electrodes and collecting electrodes in the electrostatic precipitator that have possibility of making the precipitator trips due to shortcircuit.
And we have thought that above problems has made reducing the boiler efficiency due to the insufficient heat exchange in the air preheaterand the short supply of the combustion air. So, to solve the problems, we have started inject Fe-based coal additive with Clinker generation
prevention effect. As a result, we achieved an enough problem solving and energy saving.

In recent years, oil prices have been rising. Furthermore, after the Tohoku Earthquake (2011) , energy-saving is important challenge for not
only at a company but at the home. A company must make an effort more by shortage of electric power supply.
Also, in the Manufactuaring department Futatsuka, the energy-saving committee was established in 1990, and we have been implementing
energy saving activities every day.
And now, a large-scale investment is reduced and it is not expected improvements in equipment replacement. We are going to build up small
results to achieve the target in the difficult situation.
This report introduces the contents of a measure and the examples in energy-saving activities.

Energy Saving by Stopping the Production Equipment Industrial Water in the Daytime
Youichi Usukubo
Osaka Mill, Hokuetsu Kishu Paper Co., Ltd.
The nuclear power plant disaster after the Tohoku Earthquake in 2011 had especially caused concern about power shortage in summer, andpower saving & measures against power shortage had taken not only at factories but at home.
Among others, Kansai region (area) has highly relied on nuclear power generation and also any nuclear power plants in this area didn't operate
in first half of 2012. Therefore, power shortage had been increasing serious problem.
Under the circumstances, as measures for energy saving, we're introducing our cases such as resuming operations of gas cogeneration facilities
which had been halted in response to the power company’s request, and energy saving activities at the industrial water facilities which showed
the effect through steady efforts of small group movement.

The Optimal Operation and Business Improvement by BTG Management System -FEMSTomohiro Umino and Keiji Aoki
Energy Systems Center, Mitsubishi Electric Corporation
Interest in FEMS (Factory Energy Management System) which performs energy optimization of the whole factory is increasing because ofissue of global environment and electric power shortage. FEMS makes it possible to reduce energy and satisfy the demand of a factory. The past
results show about 0.5〜1% of fuel cost and greenhouse gas can be reduced by FEMS. The eﬀect by FEMS is not only an economic aspect. It
can be said that greenhouse gas was reduced, because the fuel to burn is reduced.
We developed FEMS in 2003. After that, we have suggested and supplied FEMS to many customers. We have continued development basedon a customer's demand and improvement. As a result, FEMS became high-precision control and a system which has an attractive support
function. This paper introduces the concept and System configuration of FEMS, the function of On-line FEMS and Off-line FEMS. After that,it explains some features of our specific technologies which are calculation method of cost merit and multi-objective particle swarm
optimization method. Multi-objective particle swarm optimization method makes it possible to become cost optimization and Greenhouse gas
minimization simultaneously.

Basic Lecture of Paper Board (2)Used Paper Recycling in the Pulping Process
Akihiro Yamamori and Taku Uchiumi
Oji Materia Co. , Ltd.
Used paper has been the main raw material for papermaking. In particular, the percentage of used paper accounts for more than 63% in Japan.
Among a variety of used paper, by establishing the used paper processing technology in accordance with the application, we have attempted toincrease in used paper utilization.
Used paper recycling in Japan has a long history as it can be found it in the recording of the Heian era. As raw material for paper, used paper
came to be used in earnest, it is 1950’s that began to blend the recycled newsprint into paperboard. Then we came to blend the used paper into
newsprint paper and low grade printing paper from 1970’s. In Japan, for the following reasons, it began to use large amount of the used paper.
a) Preparing for the depletion of the wood resources in the future, b) Energy consumption for pulp production process and the cost of the raw
material is lower than fresh pulp. Moreover, with the development of the ink removal techniques from used pulp, the amount of the used paper
has grown rapidly. This time, we outlines how to process the used paper into pulp through pulping process and stock preparation process. I

Cellulose Nanofibers Prepared from Wood Pulps, Their Characteristics and Potential Applications
Akira Isogai
Department of Biomaterial Sciences, Graduate School of Agricultural and Life Sciences,
The University of Tokyo
Fundamental characteristics and potential applications of cellulose nanofibers prepared from wood bleached chemical pulps by TEMPOmediated oxidation are reviewed based on the results obtained in our laboratory up to now and during collaboration studies with companies anduniversity laboratories. Significant amounts of C6-sodium carboxylate groups can be formed selectively on crystalline cellulose microfibril
surfaces in wood pulps by TEMPO-mediated oxidation in water at pH 10 within 2 h. The TEMPO-oxidized pulps with sufficient amounts ofcarboxyl groups are then convertible to highly crystalline nanofibers uniform 3-4 nm in width and > 1 µm in length, which are individuallydispersed in water, by mild mechanical disintegration. Electrostatic repulsion and/or osmotic effect works well between anionically charged
TEMPO-oxidized cellulose microfibrils (TOCNs) in water, thus resulting in the complete and efficient individualization of wood cellulose
microfibrils. Transparent and flexible films with high strength, low oxygen permeability and low coefficient of thermal expansion are obtainedby casting the TOCN/water dispersions on a plate. The TOCNs are expected to be used as new environmentally-compatible and bio-based
nanofibers in the fields of high-performance packaging components and other high-tech devices.

New and Renewable Energy Division, Agency for Natural Resources and Energy, Ministry of Economy, Trade and Industry
In our country which is a resource-poor country, face large introductory expansion of renewable energy against the background of rapid
increase of the energy demand by newly emerging country, and the correspondence to a global warming.
Japan started feed-in tariff scheme in July, 2012. Under the feed-in tariff scheme, if a renewable energy producer requests an electric utility tosign a contract to purchase electricity at a fixed price and for a fixed period guaranteed by the government, the electric utility is obligated toaccept this request.

Introduction of Energy-Saving Technology in the Industrial Thermal Power Plants
Toshi Ishimura

MITSUBISHI HEAVY INDUSTRIES, LTD.
Due to the background of recent social situation, it is considered that thermal power plants recently play an important role in stabilizing
electricity supply. Thermal power plants, of course, use fossil fuels such as coal, LNG and petroleum which are almost all imported to Japan.
The cost of fossil fuels is the most important problem in industries. This paper outlines energy saving technology so that the fuel cost will be
reduced through various countermeasures.

Energy Saving for Approach System
Toshio Dousaka
Paper Machine Eng. Dept., Voith IHI Paper Technology Co., Ltd.
In recent paper industry situation, to enhance the production efficiency is one of the most important issues. Especially energy saving is theessential part of the production efficiency. The quality of waste paper, however, is getting worse for decades, and customers’demand of to keep
or get better quality is increasing. Our technological development has been for their answer. For example, LP screen acquire dramatic energy
saving and best screening efficiency, and IP pulper also get much better defibering efficiency with much less energy consumption. Bothproducts perform their ability not only at their part but also in the whole system. This new concept will supply the solution of the paperindustry, and we strongly believe it will be new standard in the future.
Both products as LP screen and IP pulper are for stock preparation system. Our technology also covers approach flow system, and have somesolutions for the energy saving. For this article, our state-of-the-art technology will be introduced especially about stock mixing, low consistency
cleaner, and approach screen.

Yashio Mill, Rengo Co., Ltd.
Rengo Co., Ltd. has set an environmental target aiming to reduce 32% of the corporate CO2 emission by 2020 compared to the 1990 base,followed by a higher objective of 50% reduction by 2050. From early on, Yashio Mill has been working on environmental load reduction
including the fuel conversion from heavy oil C to natural gas, utilization of paper sludge as biomass fuel, and installation of high-efficiency
equipment in the whole process.

Incidentally, a stricter local regulation has been in effect since 2011 in Saitama Prefecture where the mill is located, which requires us toreduce 15% of the CO2 emission during 2015 and 2019 relative to the average value from 2001 to 2004.
Under these circumstances, Yashio Mill launched a new energy-saving project team in March 2011 composed of members from various
sections. With the aid of an external energy-saving consultant firm, the team named “TNP (meaning low-fuel consumption) Yashio” expands
cross-sectional activities for further CO2 reduction.

Pulp＆Paper Engineering Gr. Account Sales Dept. Ⅰ Sales Div.Ⅱ., Yokogawa Electric Corporation
In Pulp and Paper industries, the cost of raw materials and energy will have major impact on the product prices.
For this reason, efforts such as energy-saving, plant optimization, high production rate improvement, are now being made to keep and increase
profits.
Moreover, the designated energy management mill has fulfilled reducing the energy consumption rate at least 1% every year constantly.
Efforts for energy reducing consumption are very important object in the mill.
It starts with current status analysis and realizes improving points.
To identify them, we need to analyze some manufacturing data and energy data. Here is our approach for the identification.

Efficient Application and Visualization of the Compressed Air
Noriyuki Mukaida
Gifu Mill, Oji Materia Co., Ltd.
Oji Materia Co., Ltd. had addressed the improvement for a purpose of efficient operation of compressors as part of energy saving project since2009. The Project had been proceeded in 2 stages, as 1st stage we carried out the investigation of air leak and improvement in order to reduce
the loss of air consumption, and succeeded to save the amount of air volume to 500,000Nm3/year.
We had achieved the introduction of visual inspection for power, pressure, blow and unify how many units are suitable for this mill by console
made by MIWA Inc.
As a result of taking actions above, we had neduced not only basic wit of air 0.144kW/Nm3 to 0.104kW/ Nm3 but also power consumption
2.8MkW/year to 1.6MkW/year.
This result shows we have adviced 40% cost reduction as an environment effects.
In the meantime,- To install the pressure monitoring alarm system,
Trend supervisions of air pressure, flow rate, power consumption- To check the basic unit of air,These operation gave a benefit below and we can find the facility abnormal promptly.
Abnormal situation of facility will be able to be recognized promptly.
As a 2nd stage, we had archived the optimized low pressure from 0.65MPa to 0.53MPa gives 130,000 kW/year cost merit.
Also in order to reduce the air consumption, we thought about purchasing devices to save energy in air blow line.

Energy Saving Solution for Paper Machine
Hidekatsu Sakurai
Paper Business Line, Metso Paper Japan Co., Ltd.
In addition to the raise of energy cost across the world, power shortage originally caused by the Great East Japan Earthquake in March 2011
has been squeezing earnings of paper making companies. As a result energy efficiency is expanding its influence in operational efficiency of
paper and board making.
Metso has been seeking the possibilities to reduce energy cost, which generally accounts for 15-30% of total production cost and has
continued making efforts for the realization. We believe that it is still possible to gain more energy saving in electric and steam consumption.

Metso's new paper making concept, OptiConcept M uses effective equipment to reduce the consumption of electricity and steam. This article
introduces promising equipment and solutions that can be applied to existing paper machines to save energy.

Introduction of Latest DD®6000 Refiner- Energy Saving by Highly Efficient Refining Yoshinori Ishikawa
Design Department, Kawanoe Zoki Co., Ltd.
GL&V/Kawanoe Zoki’s latest double disc refiner “DD6000”achieves highly efficient refining by Equa-FloTM technology,one of the spline
technology. Kawanoe Zoki has proposed to upgrade existing DDR with the Equa-FloTM technology, and high energy saving performance was
successfully completed in the result.
DD6000 performs energy saving by 40% and capacity increase up to 50% compared with conventional refiner DD4000.
Above high performance is accomplished by its unique technologies. The Equa-FloTM technology is the only technology that has ports in the
hub rather than in the rotor. This eliminates all forces on the rotor and results in the most balanced centering rotor. One high performancerefiner plate has no area for bolts in refining area and this leads to more efficient refining performance. The other high performance refiner
plate has zero degree draft and results in keeping constant refining performance throughout plate life time. Tangential inlet and outlet increaserefiner capacity and tangential inlet saves energy consumption as well.
DD6000 would be one of the best solutions to save energy and reduce operating cost for your stock preparation system.

Issues and Solutions for Light Weighting on Paperboard
Yasuhide Yoshimoto and Kazuhide Yoshikawa
Paper Chemicals Development Section, Research & Development Center, Researh & Development Co.,Harima Chemicals, Inc.

In recent paper & paperboard industry, we focus on high efficient production, the technologies for saving resource, and saving energy to use
energy effectively for environment on the earth. Regarding to paperboard making, there are some trends such as machine speed up to improve
productivity, increasing calcium carbonate due to using magazine recycle-fiber, and closed papermaking system in corresponding to waste
water for environmental issues. These trends cause lower retention of fibers and internal additives, decreasing of fiber strength by itself, scaling,
and increasing electrical conductivity, temperature and chemicals dosage (per unit). In addition, the light-weighting is progressive for resolving
environmental issues with saving resourcing. However, it is getting difficult to keep strength properties such as compression and burst strengths
at the papermaking with conventional internal additives because compression and burst strengths depend on basis weight. We have suggested
the total wet end system, total chemicals on wet end process with alum performance for quality improvement, and surface treatment withcoating additives for the light-weighting at the annual meeting of 2005 and 2010. In this report, we introduce our technologies such as internal
dry strength agent (PAM) and surface treatment with coating PAM, in addition to developed coating PAM and coating agent for cracking
problems during creasing, on the issues and solutions for light-weighting on paperboard.

Development of High Quality Porous Fillers (Part3)- Scale-Up Trials at Pilot and Mill Plant for High Quality Porous Fillers Precipitating silica which is also called porous fillers has a low specific gravity and has frequently been used as a filler to increase paper
bulkiness. Uses of porous fillers do not cause problems such as discoloration which occur with machine pulps and staining paper machines
which often occur when using fatty acid derivative and special surface-active agents as a bulking agent. Rather, they are advantageous in termsof cost such as that they reduce the drying load of paper machines by decreasing the amount of pulp to be used and decreasing the amount ofpulp while maintaining the same paper thickness. However, they still have a problem of degrading paper strength. Therefore, we explored ways
to develop high quality porous fillers which have high paper-bulking properties and great opacity. In the last report, we reported that having
alkaline-resistant microparticles available during reactions enabled a control of primary particle diameter, secondary coagulation particle
diameter, and particle size distributions which were particle properties, resulting in high quality porous fillers with a low level of paper strength
degradation.
In this report, we studied a scale-up of this process and achieved low level of paper strength degradation with controlled particle properties in
an industry level.

Current State and View in the Future of Domestic Forest
Kusuo Akahori
WriterIn "Forest and forestry revitalization plan" that had been made public in December, 2009, the target to be going to raise rate of self-sufficiency
to 50% within ten years in the future was set. As a result, various approaches to increase production of wood are examined in a domestic eachhome.
However, the rate of self-sufficiency of wood has stayed in the latter half of the level 20% now. In this report the current state and the prospectin the future of domestic forest are described.

Global Woodchip Demand and China Impact
Shoji Yabe
Paper Products & Material Department, ITOCHU Corporation
Generally speaking, woodchip used as raw materials for paper manufacturing is being produced locally for local consumption in many
countries and woodchip imports trade has concentrated in Asia and parts of Europe.
Japan has been the leading country in woodchip import trade and it has recorded 14 million Bone Dry Tons (BDT) in 2008, their highest
woodchip import volume ever but due to decline in Japanese economy and increase in paper imports into Japan after the ‘Lehman shock’or
Global Financial Crisis, this import volume is now around 80% of 2008 import level.
While we saw a large decline in woodchip imports into JPN, there has been a large increase in woodchip imports into China, increasing fromabout 1 million BDT in 2008 to 7 million BDT in 2012, and this is expected to reach 11 million BDT which is similar to Japan volume in thenext few years.
We have also seen a sharp increase in woodchip export volume from Asia such as Vietnam & Thailand, going from 1 million BDT for Vietnam
and 0.7 million BDT for Thailand in 2008 to 5.8 million BDT and 2.9 million BDT respectively. Woodchip export volume out of Vietnam andThailand is now no.1 and no.3 in the world.
Due to these factors, demand for woodchip import which is focused on Hardwood to China is actually increasing in the Pacific Rim region andmarket share on woodchip trade held by Japanese Paper companies is said to drop to around 50% of total Asian woodchip import demand by
2015. There are fears that this will lead to weakening of influence Japanese Paper companies will have in woodchip price negotiation in the
future.
Considering the demand by China and in recent years, India and alternate use of woodchip such as particle boards and wood based biomass by
China & Korea, issues Japan will face would be effective utilisation of domestic resource and to secure resource in mid to long term.
Based on this situation, I will be trying to clarify current status of global woodchip supply & demand, as well as impact China will have in the
future.

Andritz Biomass Technology for Cost Reduction and New Business
Kanji Hagiwara
Capital System Sales Group 1, Andritz K.K.
In worldwide, energy source has been moving from fossil energy to renewable energy due to the request of CO2 emission decrease. In addition
to the request of CO2 emission decrease, we are also strongly moving to renewable energy due to the nuclear power plant issue in Japan. There
are hydraulic power, solar power, wind power etc. as renewable energy. But biomass also is very important renewable energy source. And pulp
& paper industry in Japan is looking for new business and cost reduction because of decrease of paper consumption and increase of material
cost (i.e. chip, fossil fuel). This Paper presents Andritz technology for biomass handling and energy and dissolving pulp technology as new
business.

TMP and CTMP Solution for a Sustainable Future
Akifumi Hatta
Sales & Marketing, Metso Paper Japan Co., Ltd.
TMP/CTMP production in the world is shrinking except in China. It is expected that hardwood CTMP production in China will increase in
the future as well.
Challenging of TMP/CTMP is how to reduce refining energy from when this process was developed. One of the mills which Metso's processwith new concept was applied succeeded to reduce main refining energy by 1400 kWh/adt comparing with conventional process and pulp is
bleached with high efficiency by MC+HC 2-stage bleaching system. It is proven in some mills that higher production rate gives lower processenergy consumption. Refiner segment with new concept is also developed for lower refining energy and higher quality. It is to combine different
concepts into one pair of segments according to refining conditions and targets in each mill.
To develop utilization of TMP/CTMP by more energy saving and higher brightness up to more than 85% ISO is the challenge for the futureof TMP/CTMP and machine/process suppliers.

Suggestions of Measures to Quality Losses of Recycled Waste-Paper
Kazumi Fujita
Technical & Engineering Department, AIKAWA IRON WORKS CO., LTD.
Recently, in Japan, the quality of the recycled waste-paper is lowering substantially. This appears to be influenced by (1) the globalization of
the distribution for the board & paper market and recycled waste-paper market, (2) the generalization of the mail-order businesses that aredelivering individual packages with plastic bags and polystyrene foam fillings, and (3) the decrease of the quantity for the writing-printing
paper, news printing paper production and the excellent recycled waste paper, and this was brought by the economic downturn or increasing
the internet and digital tools. On the other hand, the higher quality of the paper stock is becoming more and more important because therequired basis weight would be lower and the required paper machine speed and stability would be higher. And also the visual quality andprinting suitability becomes more and more important because for example the liner surface quality needs to be higher to suit the merchandise
display with a shipping package box.
Of course, saving energy and reducing fiber loss as much as possible are permanent targets from the points of view of cost-wise and reducing
emissions. Today it becomes more important task because the higher quality board and paper would be necessary due to the lower quality
recycled waste-paper.
In this report, we, AIKAWA would like to introduce the measures to quality loss of recycled waste-paper by applying our newest technology tothe existing stock preparation system (from pulper to the paper machine approach system).

The Approach to the Deteriorated Kraft Pulping Plant
Nakamura Wataru
Kasugai Mill, Oji Paper Co., Ltd.
Kasugai mill, Oji Paper, has started the operation in 1952, as fine paper making plant which introduced Japan's first commercial Kamyr-type
continuous digester and multi stage bleach line. It has now taken the lead in Oji Paper as the integrated pulp and paper plant with producing
several paper grades, through a couple of new installation, reinforcement, replacement and modification.
Recently, Japanese paper industry has been in a tough situation, since the domestic demand of paper has reduced and the imported paper has
increased. In such a situation, the replacement including S&B has been severely restricted, and the maintenance on existing facilities has
become the key in managing plant operation. In our mill, equipment failure led to production loss had been recently increased because
numerous facilities might be deteriorated by long term operation.
The production losses by equipment failure and mistake in operation have not an impact on business productivity but also safety andenvironment aspect, so that a couple of countermeasure have been scheduled with based on analysis of production loss cases.
The five cases of deteriorated equipment failure are reported in this article with cause and solution.

Establishment of Kiln Calcination Capability Reinforcement Constructionand Its Operation Method
Tadashi Horiuchi
Iwakuni Mill, Nippon Paper Industries Co., Ltd.
At Iwakuni Mill and Otake Mill which locates next to it in Nippon Paper Industries, the production system of pulp and paper is needed toreconstruct for the purpose of earning recovery.
As one of the measure of this, we try to make more competitive Kraft Pulp by curtailing the production of pulp at Otake Mill indefinitely,
consolidating production into Iwakuni Mill and providing Otake Mill with pulp.
For this reason, it becomes more important to produce pulp stably. To achieve this, there is priority issue - ‘poor capacity of caustic process’ tobe solved. Especially lack of capacity of hot lime production in kiln is bottleneck in our caustic process when we make up enough white liquor
for two digesters in full swing. Dealing with this problem from the aspect of improvement of facilities, usage of chemical an examination ofoperating condition, we achieve to produce sufficient white liquor by increasing hot lime production.

Quality Accident and Countermeasure Due to Pulp Equipment FRP Deterioration
Nobuo Oikawa
Kitakami Hitec Paper Corporation
For the first time, we experienced the trouble of the quality by degradation of the FRP material currently used for pulp equipment in theoperation over many years. It was difficult to discover the place which dirt generated at the beginning. At last, it turned out that heat treatmentchanges it into yellow from white, and it has the feature which shows a fluorescent reaction. From the feature, we created the judgment method
about the quantity of that, and conducted investigation about it. As a result, it became clear that it is based on degradation of the FRP material
currently variously used at the pulp process. After that, the generating place of that was discovered, and as a result of performing various
measures, generating of that will not take place.
This report describes progress from discovery of dirt to solution.

The Fire Measure at Wood Chip Handling Process
Shinpei Miyake
Niigata Mill, Hokuetsu Kishu Paper Co., Ltd.
We treat a lot of combustibles at the wood chip handling process, so it is always put to the risk of a fire. Actually, at conveyer for wood chip,many fire accidents have been reported. At wood chip handling process which is the uppermost part of a factory, an outbreak of fire has aserious influence on factory operation. That's why the fire prevention is strongly needed.
At Niigata Mill of Hokuetsu Kishu Paper, the fire measure at wood chip handling process is filled with much more power from around 2009. In
this news, I'd like to introduce some measures against a fire, for example, improvement of operation and equipment, introduction of atemperature monitoring system, and so on. Those measures are introduced at the “Kvaerner line”, with a larger production between two lines ofthe pulping process in Niigata Mill.

Lignocellulose- Releasing of Environmental Factors and Sequential Functionalization Masamitsu Funaoka
Graduate School of Bioresources, Mie University

In order to achieve the cascade-type flow of lignocellulosic components as functional materials in human life, a novel conversion system has
been developed and a new type of structure-controllable lignin-based polymers (lignophenols) has originally been designed. The originallydesigned process includes the phase-separative reaction system composed of phenol derivatives and concentrated acid. Through this process,native lignins are converted quantitatively to a new type of lignin-based polymer (lignophenols) composed mainly of 1,1-bis(aryl)propane typeunits. The selective grafting of monomeric phenol derivatives to C1-positions of propane units leads to the formation of new phenylpropane
units between grafted phenolic units and lignin propane units, resulting in a dramatic change of the original lignin functions. The characteristic
units in lignophenols, 1,1-bis(aryl) propane-2-O-aryl ethers, can be used as switching devices for the structural control. The separated
carbohydrates include water-soluble monomers, oligomers, and polymers. These are easily converted to valuable chemicals such as alcohols,
lactic acid, furfural, xylitol, etc. In order to create sustainable human society without petroleum, aliphatic and aromatic types of industrial raw
materials must be derived sustainably from biomaterials (lignocellulosics). A new sustainable industrial network initiated from forests isdesigned.

Basic Lecture of Paper Board (3)Used Paper Recycling in the Paper Making Process
Akihiro Yamamori and Taku Uchiumi
Oji Materia Co. ,Ltd.
The paper-machine is generally consisted of the headbox, the wire part, the press part, the drier part, the calendar, etc., and each part had
simple structure once.
Moreover, since opration of the paper-machine depended on operator’s experience, knowledge and intuition concerning about operation
method of equipment, it was difficult to get the stable quality of paper and condition of the paper-machine.
However, various research and development and continuous progress of various equipment have caused the drastic improvement of theperformance of a papermaking process.
We describe the outline of the structure and principle about each papermaking process.

Research Report
Strength Properties of Wet-Combination Paper
Takushi Sakaemura
Paper Chemical Division, Arakawa Chemical Industries, Ltd.
Yamauchi Tatsuo
Graduate School of Agriculture, Kyoto University

The effect of wet-combination of paper plies on some basic strength properties was investigated by using a series of wet-combined papers
from lightly and heavily beaten pulps. As the basic in-plane and out-of plane strength properties, tensile, compressive, and internal bondstrength were measured. Microfailures which are detectable as acoustic emissions (AEs) and occurred during the tensile deforming process
were further examined to investigate the effect of wet-combination of paper plies on in-plane tensile strength. The results showed that anincrease in paper ply by wet-combination brought about an increase in the plastic deformation region, leading to higher strain at breakage andan increase in tensile strength as a result of the higher strain at breakage rather than that of the increase in fiber bonding. Compared withhomogenous paper made by pulp mixing, the presence of a strong paper ply within paper layer by wet-combination, irrespective of its zdirectional position, may increase the period of gradual increase in microfailures at the plastic deformation region and delay the acuteoccurrence of microfailures just before the maximum load. The increase in microfailures accompanying the increased period of the plastic
deformation by wet combination had little effect on the origin of microfailures. Strong paper plies located at both outer sides could prevent thedevelopment of microfailures connecting to paper sheet failure, and eventually resulting in higher strain at breakage and an increased tensile
strength. In contrast to tensile strength, compressive strength in the X-Y direction was simply determined by the content of highly beaten pulp,
regardless of the manner of combination, i.e., wet-combination or pulp mixing. Tensile strength in the Z-direction, which is evaluated asinternal bond strength, was determined by that of the weakest paper ply and wet combination brought about a further decrease in the Zdirectional tensile strength.

Development of Imaging Materials for Electronic Paper by Using I/O Values
Ryohei Nakazawa, Ryo Tanizaki, Motochika Yukawa and Shuichi Maeda
Optical and Imaging Science and Technology, Tokai University
Electronic paper plays an important role in information devices, principally due to readability under high ambient light and low power
consumption. In electronic paper, microcapsule electrophoretic display is most preferable system because it has good readability which is close
to that of conventional paper. Particles as display elements of an electrophoretic display are covered with polymer surfactants which preventthese particles from co-aggregation. The key technology in obtaining successful electrophoretic displays is utilizing appropriate surfactants fordispersing these particles. It generally takes long time and high cost to find such surfactants. To reduce the R&D time and cost, finding usefulparameters for appropriate suitable surfactants is necessary. This paper focuses on the effect of I/O values as the parameter, particularly
emphasizing use in surfactants and dispersion media. Model display units containing silicone oil as a media, titanium oxide and iron oxide
particles covered with/without octyltriethoxy silane or fluoro silane were prepared in order to investigate the effect of I/O values. The motion ofthese particles in the display units were observed in the presence/absence of magnetic field. The separation and re-dispersion cycle can beobserved repeatedly with the only display unit which contains both titanium oxide and iron oxide particles covered with octyltriethoxy silane in
the silicone oil. The repeatability of separation and re-dispersion seems to come from the I/O value (=0.39) of particles covered withoctyltriethoxy silane which is quite close to the I/O value (=0.40) of silicone oil. This repeatability is crucially important when considering
applications such as electronic books. Through experimental works including above, we believe that I/O value is one of the useful parameters inorder to develop appropriate surfactants for display elements of electrophoretic displays.

Measures against Profit Improvement of Folio Sheet Cutter
Kenji Nakano
Nichinan Mill, Oji Paper Co., Ltd.
In the Folio sheet cutter of our factory, because jamming occurred when adsorption timing of sheet slipped off in a suction box part, we
adjusted a timing at the change of dimension and change of shifts. Because products exhausted at this time, it became the factor of a decrease inproduct yield. In addition, because the jumping out of the sheet occurs to a product when we adjust a timing, it was necessary to sort a product.
Therefore we installed an image processing device and worked on loss reduction.

Operating Experience of New Sheet Finishing Machines- Sheet Cutter・ Ream Wrapping Machine・ Skid Wrapping MachineShigeyoshi Tsutsui
Hokuetsu Kamiseisen Co. Ltd.
Japanese paper companies have to enhance the export with international competitiveness due to the decline of the domestic demand.
According with the export strategy of Hokuetsu Kishu Paper, Hokuetsu Kamiseisen has built up the machinery. We target the export sheet
paper that is in a good demand. Export sheet paper is relatively small, that affects the cut efficiency. In choosing the machines, strong wrappingthat endures the marine shipment is also an important point. Machines we introduce are as follows, Pasaban-made 2 sheet cutter machines
operated since 2013 spring, Maruishi-made 1 ream wrapping machine operated since 2012 autumn, JTEC-made 1 skid wrapping machine
operated since 2012 spring. We report the operating experiences of new sheet finishing machines.

Recent Trends in Coating Pigment Use and Formulation Practice in Asia and Western Markets
Etsuya Misawa
IMERYS MINERALS JAPAN K.K.
Chris Nutbeem
IMERYS Minerals Ltd.
Pigment use and formulation practice in coated papers has seen marked changes in the past 40 years. In general the trend was for coatings to
become increasingly more sophisticated in order to meet the advertising world’s need for better visual image. That together with machinery
advances had driven significant pigment developments up until the mid-2000’s.

Now, however, the world has changed. The global downturn in 2008/9 together with ever increasing competition between print and digital
media has fundamentally changed the global paper industry. It is clear that cost is now the main driver affecting coating recipe design anddevelopments focused purely on improving quality are now largely a thing of the past.
In this paper we explore the changes in the global and Asian paper markets that have occurred since the peak in 2007 and how these changes
have affected pigment demand, pigment use and formulation design.
We conclude by looking at what this could mean for future pigment demand and show how kaolin, which has declined recently in recipes, canstill bring value to paper making.

Development in Strength Enhancement
Shintaro Nakayama, Patrik Simonson, Joakim Carlén
and Michael Persson
Pulp and Performance Chemicals Division, Akzonobel K.K.
With pulp prices being high, fine paper makers looking to reduce costs are constantly trying to increase the filler level in their paper. The
optical properties will often benefit from increased filler content but the mechanical properties will deteriorate and the retention can be difficult
to maintain. The reasons for a weaker paper sheet in a highly filled paper are fewer fibres per unit volume paper and filler particles interferingand disturbing the formation of fibre/fibre bonds plus the risk of filler particles creating defects in the paper material 1). Besides elevating fibre
cost, the deteriorating quality of raw material has rapidly increase the need of strength enhancement additive .The amount of paper and boardthat is being recycled is increasing and therefore rapidly decreasing the amount of fresh fibre addition. Addition to the above mentioned
strength deteriorating factor, the drive to decrease the basis weight of both paper and board has also directly impact on higher strength
enhancement requirement.
In order to answer the needs of the paper and board industry on strength enhancement, our goal is to increase the in-plane and out-of-plane
strength by 20 and 30% respectively or decreasing basis weight of packaging material by 10-15%.
To achieve higher filler levels and maintain or improve the quality of the paper a new concept has been developed, the so-called EcoFill™
system. EcoFill™ consists of a filler modification system, including an on-line filler treatment system, with charge control additives and anengineered cellulose additive. The engineered cellulose additive (ECA) improves the bonding at the interface between the filler particles andbetween the filler and fiber in the sheet. This gives significant internal bond improvements. The charge control components enable a goodbonding between the filler and the ECA and secures that the wet-end conditions are stable for optimum performance of other wet-end additives
such as sizing agents.

Moisture Measuring System by Dielectric Property
Shinichi Kitagawa
Group Technology Div., Oji Engineering Co. Ltd.

The infrared method is the most popular to measure the moisture content in the coated layer on the paper sheets or polymer films. But thismethod is not suitable for measuring only a little moisture content, for example less than 1 %, with high accuracy because of the influence of the
disturbance such as heat source. It is also affected by the color of the sample in principle. In order to solve these problems, a new moisture
analyzer using a microwave resonator has been developed. This is based on the difference of the dielectric loss between the water and the paper
sheets or polymer films. This report describes the measurement principle, some data and a few applications of the new moisture analyzer.

Our Vision of Sophisticated Color-Web Inspection System for Paper Production
Jun Ikeuchi
Inspection Systems Business Div., Omron Corporation

has developed Color-WIS over the past 20 years. As a result, we are able to apply our Color-WIS in various kinds of paper. Today, we would liketo show you our original solutions and values that Color-WIS can provide on site, and indicate an application possibility with our patenttechnology.

Improvement of Paper Properties and Reduction of Environmental Load by a New Starch Fixing Technology
Yuko Okusa, Chigusa Taguchi and Hiroyuki Suzuki
Kurita Water Industries Ltd.
Base weight reduction is a very useful way for many board manufactures to save natural resource, and reduce carbon dioxide emission. But inthe mean time, the cost is increasing because more starch or other dry strength agent is needed for keeping the same sheet strength. This paper
aimed at how to effectively use the starch resource in the raw material of old corrugated container, which is contented of several percent ofcorrugating adhesive starch. However, the starch is usually difficult to retentive and easily bio-degraded in the paper making process. It could
be solved by a properly designed microbe control system and a new developed starch fixing agent. As a result of mill trial, not only improvementof the sheet strength but also a lower COD in the effluent was achieved.

Current Techniques for Pest Control in Paper Mills
Masahiko Konishi
Sales Department, Ikari Corporation
Recently, many paper mills have been monitored the abundance and distribution of insects as a part of pest control inside of each factory. The
light traps with sticky sheets are often used in monitoring of insects. In generally, the sticky sheets are replaced approximately every one month,and collected insects are counted and identified by technician. Pest Control Operators (PCO) have been controlled the insects based on the
results of monitoring and worked to maintain and improve the sanitation management of the production area. However, because of response to
growing safety awareness of consumers from year to year, PCO are necessary to control the insects by more rapid and lower environmental
impact.
In this paper, I elucidate the efficient original monitoring methods and effective original control methods in various manufacturing factories
including paper mills.

European Patent with Unitary Effect and Unified Patent Court
Toshinao Yamazaki and Hiroshi Kawamata
Japan Patent OfficeAtsuya Takeshita
Cabinet Plasseraud

The long-awaited legal framework to establish the European Patent with Unitary Effect and Unified Patent Court was concluded in February,
2013. The Unitary Patent package is composed of two EU Regulations for Unitary Patent and one Agreement for Unified Patent Court.
While some users look forward to the new patent system because it is believed to be more convenient and more effective than the current
European patent system, some users are concerned about the complexity and uncertainty. In order for Japanese users to become more familiar
with it, this article illustrates the background of the discussion and overview of the Unitary Patent package.
Unlike the classical European Patent, which is so-called "the bundle of national patents," the Unitary Patent will bring a unitary effect within
the territory of all the participating member states and it seems to become an efficient tool if an applicant needs to acquire the patent protection
in many states in Europe. However, the procedure of the Unitary Patent from filing to registration will be done before the European Patent
Office, based on the European Patent Convention. Thus, the examination process of the Unitary Patent, basically, will not be different fromthat of the classical European Patent.
The Unified Patent Court is a new centralized patent litigation system in Europe and will have the exclusive jurisdiction for any infringementcases and revocation cases of both the Unitary Patent and the classical European Patents after the 7 years or 14 years of transitional period.
The Unitary Patent and Unified Patent Court are hoped to become one of the useful tools for Japanese users who run the business in broad
areas in Europe as well as European users.

Research Report
Radical Trapping Mechanism of Mannitol in Fenton Reactions
Kengo Magara and Tsutomu Ikeda
Forestry and Forest Products Research InstituteMannitol is a well-known radical trapping reagent, though the trapping effect is difficult to confirm in a Fenton reaction. Under acidic
conditions, mannitol was consumed during the Fenton reaction, as well as other substrates, such as vanillyl alcohol, veratryl alcohol and Methylβ-D-glucopyranoside. Under alkaline conditions, however, only mannitol was consumed during the reaction.
When we investigated the solubility of iron (Ⅱ) and (Ⅲ), which work as catalysts to initiate the Fenton reaction, the addition of mannitol was
found to help dissolve the iron compounds in alkaline solution, especially those exceeding pH 10, though iron compounds are not soluble undersuch alkaline conditions. Based on this result, mannitol is considered to form a complex with iron (Ⅱ) and (Ⅲ) ions under these conditions andthe hydroxyl radical (HO･) generated by the reaction between hydrogen peroxide and iron (Ⅱ) and (Ⅲ) complex of mannitol will attack themannitol because it is the compound nearest the site where the HO･ is generated.

The Paperboard Trend of Malaysia and Southeast Asia and the Experience of Paper Mill Operation
Shinji Matsuyama
Paper Division, GS Paper & Packaging Sdn Bhd
Recently，The domestic paper industry is facing an unprecedented crisis, because paper demand has slumped due to a combination of factors
such as advanced in ICT, the hollowing out of domestic industry accelerated by persistent yen appreciation, and an aging society with a lowbirth rate. In addition, imported paper has taken hold in an increasingly globalized market. Therefore, We have to expand our overseas businessand corporate with oversea Oji group to adapt with those severe condition.
Oji Holdings has been expanding overseas business from the 1970s, We started new slogan " Pursuing Efficiency in Domestic Business""Expansion to Overseas" in 2001 , and then , We are proceeding streamline our domestic production structure and reducing cost to stabilize ourearnings base .

On the other hand, We are aggressively cultivate business in overseas in markets with growth potential such as Asian area. GSPP become Ojigroup in 2010.4 and We found Oji Paper Asia in 2010.10 in Malaysia. As a result, Malaysia is one of the most important area for us.
This draft outlines the paperboard trend of Malaysia and Southeast Asia and the experience of paper mill operation.

The Proposals for Cost Reduction of Paperboard Production
Kenji Sakai, Naho Murata, Hidetoshi Sakamoto and Tomonori Nakamura
Shonan Reserch Center, HYMO Corporation
In this paper, we propose cost reduction of paperboard by reducing pitch-troubles and improving the efficiency of wet-end additives.
FR-801, FR-701H, and MT-910 are cationic organic polymers whose molecular weight, charge density and composition are designed
appropriately, therefore, they are very effective in reducing pitch troubles such as web breaks and pitch deposition on machinery. These
polymers also have high ability to fix size on pulp effectively and to decrease consumption of size. Furthermore, these polymers can be used as a
substitute for Alum.
In order to prevent the excess consumption of additives, selecting the most suitable drainage and retention aids (D-R aids) are important. The
effects of D-R aids depend on the kinds of machine and paper, and are influenced by pH, electric conductivity, alum and paper strength agents.
Therefore, we have been developing the different type of D-R aids with various charge density and flocculation ability. The polymers of theseD-R aids have been designed as the contracted conformation in order to improve retention and drainage without the deterioration of
dewatering, formation and paper strength. As the result, excess consumption of other additives is restrained.
Using these additives having high abilities can decrease the consumption of paper additives and improve runnability. And consequently, it iseffective in reducing production cost.
KeyWords: pitch, size, retention, drainage, alum, paper strength agent, paperboard, cost reduction,

The Measure for the Dissolved and Colloidal Substances in Linerboard Papermaking
Toshio Hokajo
Paper Chemical Business Division, Seiko PMC Co., Ltd.
Recently, in paper mills, white-water closed system by decreasing the usage of fresh water, increase of the usage rate of recycled pulp andreduction of basis weight of paper and paperboard are progressed. Under these circumstances, more contaminants tend to exist in papermaking
systems. The contaminant is often called "anionic trash" and known that it is concerned to cause the lower productivity owing to the poor
retention of pulp fiber and chemicals. However, there are few reports on qualitative and quantitative analyses on the contaminant.
So, we define all of the substance except water and pulp fiber existing in papermaking systems as DCS (Dissolved and Colloidal Substances)and carried out detailed analysis on DCS obtained from paperboard mills.
From the analytical results, we clarified that DCS in paperboard-making system mainly consists of calcium, sulfates, starches, small organic
acids, etc. Because these components may cause the troubles such as poor retention, growth of pitch, scaling and a bad smell, measures for DCS
are needed. It is considered that measures include retaining DSC on paper with coagulants and dosing chemicals hard to suffer from DCS. In
this report, we introduce evaluation results of high performance coagulant for DCS "AC7314" and novel dry-strength agents hard to be affectedby DCS.

Operating Experience of Lime Kiln with BrainWave-ACE System
Yasuyuki Sato
Ishinomaki Mill, Nippon Paper Industries Co., Ltd.
KP plant at Nippon Paper Ishinomaki mill has two sets of rotary kilns, No.1 lime kiln (3.36m 90mL) and No.2 lime kiln (3.20mΦ 70mL).
Although lime kiln utilizes heavy oil as an energy source, the increase in manufacturing cost is remarkable due to a sharp rise in the price ofheavy oil in recent years. After the startup of the biomass boiler in 2006, Oil usage of the lime kilns have come to account for almost half of theheavy oil usage of whole mill.
To reduce the amount of the kiln heavy oil used, we implemented the advanced control system "BrainWave-ACE" in 2010. In this paper, we
report on operation experience of the kiln with BrainWave-Ace. Although this system has many installation records overseas, it is first
installation in Japan.

Paper Machine Eng. Dept., Voith IHI Paper Technology Co., Ltd.
This article gives readers a overview of our completely new technology development for premium tissue production. Voith Paper launched thisinnovative technology under the name “ATMOS (Advanced Tissue Molding System).
For more than 30 years, premium tissue was produced only by the largest tissue paper producers, using Through Air Drying (TAD)
technology. Only they could afford the high capital investment involved and the high production cost mainly attributable to energy
consumption. But the innovative Voith ATMOS technology has changed this situation. ATMOS technology was developed at the Voith Tissue
Process technology Center in Sao Paulo, Brazil in close teamwork with Voith Paper Fabric division. Thanks to this development, premium
tissue can be produced at much lower investment and energy costs, also saving fiber and even using 100% recovered paper furnish.

Chemical Structures and Their Properties of Wood Components
Toshiyuki Takano
Graduate School of Agriculture, Kyoto University
It is thought that wood components are produced by a tree for its survival, and have suitable chemical structures for the purpose. Then, theelucidation of relationship between chemical structures and their properties is one of the important approaches for new effective utilization ofwood components. In this seminar, fundamental explanation for chemical structures of wood components and recent studies of woodcomponents in our laboratory are mentioned.
Wood consists of main component (cellulose, hemicellulose, lignin) and minor component (extractives). Cellulose has a suitable chemical
structure for crystallization (linear polymer with strictly regular structures), and is a construction material of cell walls. Hemicellulose has asuitable chemical structure as an amorphous material, and contributes to the formation of 3D structures of cell walls. Lignin is an aromatic
polymer, and plays important roles for the formation of vascular bundle in a tree. Extractives are the important components for controlling thecharacteristic properties of each tree. As our recent studies, the new analysis method for Lignin-Carbohydrate Complex (LCC) and novel
cellulose derivatives for photo-current generation system are also described.

Cellulose Nanofiber for Energy and Materials Production
Takashi Endo
Biomass Refinery Research Center, Advanced Industrial Science and Technology
In recent years, the development of utilization technology of woody biomass for energy and material has attracted much attention. The main
component of wood is cellulose. The nature of cellulose in wood is an assembly of cellulose molecules called the cellulose microfibril. Cellulose
nanofibers are bundles of cellulose microfibrils and have the feature of high strength and lightweight.
In this study, we have used cellulose nanofibers obtained from wood as a core material, and have developed the nanofiber reinforced
composite and the pretreatment for enzymatic saccharification (bioethanol production). Cellulose nanofibers can be directly prepared fromwood by the combined process of wet-milling and hydrothermal treatment (hydrothermal-mechanochemical treatment). The nanofibers have avery large surface area. Therefore, the enzyme readily accesses the cellulose molecules and saccharify.
In the production of nanofibers, water is essential. Thus, the drying process is required in the compounding of nanofiber with resin. However,the nanofibers tend to aggregate each other. We tried several methods to prevent aggregation of nanofibers in the composite. As a result, themasterbatch method was effective in dispersing of the nanofibers. The masterbatch was prepared by directly blending the nanofiber slurry into
the low melting point polyolefin, evaporating water. The nanofiber-polypropylene composite containing just 1wt% nanofiber showed highstrength and high elongation.

Activities for Energy Saving in Yonago Mill

Yonago Mill, Oji Paper Co., Ltd．

At our YONAGO mill, all members are working on the target "1.5% reduction of the total energy of our mill".
However, it is becoming more and more difficult year by year to find new or drastic energy-saving matters.
In spite of this difficult situation, by focusing on several projects, we have been successful in reducing the energy consumption of our millcontinuously.
This paper reports how we can achieve our target, and our energy-saving cases.

NeOCOAT is a next generation eco-paint which consumes heat by converting thermal energy to kinetic energy using ‘heat-exchange
molecules' in paint. NeOCOAT can be applied to a wide range of surfaces including roofs, pathways, sports grounds, parking areas, indoor
surfaces, and play equipment.
In addition, it is effective in reducing air-conditioning costs and controlling condensation.

The Efficient Energy Reduction Method by Fixed Orifice Type Trap
Masaki Kimura
Z Engineering Co., Ltd.
In paper pulp industry there are many processes of performing indirect heating by steam, and the steam which emitted heat is discharged fromthe steam trap as condensate. If a steam trap deteriorates, steam leaking will accrue, so the steam consumption of the whole factory tends toincrease every year.
Although the steam leak rate from a steam trap is different with an operating condition, preservation frequency, etc. an average loss rate
exceeding 10% has also been reported, therefore can say that to reduce steam leakage from steam trap is an important factor for energy saving.
In order to reduce steam loss, it is necessary to perform check and replace of steam traps frequently. however, if it is a large-sized factory,
thousands or much more steam traps are also installed, so it is easy to imagine that is considerably hard to do it from the point of view of thelabor and cost. Therefore, the repair of the steam trap is carried out after a steam leak trouble is actualized. And the steam loss before the repair
is ignored.
We propose the energy saving maintenance system using the "fixed orifice-type steam trap" which does not have a deterioration part unlike thesteam trap as consumption part. This report introduces the introduction of the "fixed orifice-type steam trap" and the reduction of the steam
leaking and maintenance cost by a new maintenance method.

Basic Lecture of Paper Board (4)The Novel Needs and Future Trend
In recent years, the change of industrial structure has been caused the change of the mainstream from paper to paperboard in paper and pulp
industry.
However, the demand of the paperboards in Japan hasn’t shown upward trend, but has maintained a flat.
Under these circumstances, the needs of customers for paperboard have shown several diversities in order to attain the cost reduction, anddistinguish other’s products. We have been conducted research and development in order to deal with customer’s needs.
On the other hand, we strive to acquire the stable profit by raising the recovery rate and blending rate of the waste paper.
We will outline the future needs and trend of the paperboard, and introduce the countermeasure to take advantage of waste paper for cost
reduction and meeting demand, trend and need.

Research Report
Performance Improvement of Activated Sludge
Masayuki Watanabe, Keiko Fujita, Miyuki Nakagawa, Hitomi Kimura and Hitoshi Okada
Japan Pulp and Paper Research Institute, lnc.
Recently, regulation for effluent standards has become stricter, due to enhanced awareness of the environmental preservation in Japan. In thissituation, improvement of wastewater treatment is important for the pulp and paper industry. The Activated sludge (AS) process is one of main
wastewater treatments and many paper mills use this process. However, it has been unclear how bacteria affect the performance of AS, and theoperation of the AS process often depends on operator’s experiences.
As a study of the development of higher performance AS, we have conducted investigations into the present situation of AS at several paper
mills. As a result, we found out that the effluent from each mill was not always most effectively decomposed by the AS sample from the same
mill. In the laboratory, we confirmed that high performance AS enabled us to improve degradability of wastewater which is resistant todecomposition. Based on the results of genetic analysis, bacteria of the order “Rhodocyclales” was likely to contribute to the performance of AS.

Development and Application of Cellgaia, the Pulp where Zeolite Crystalized Densely Inside of the Wood Pulp
Kouju Sugiyama and Kaoru Yamaguchi
Central Laboratory, Rengo Co., Ltd.

Zeolites are a family of minerals known for their powerful deodorization and anti-bacterial effect that are supported by metals such as copperand silver. In recent years attention is also being paid to zeolites for their ability to absorb radioactive materials that are dissolved into water.
Despite this advanced function, until now there were no effective methods for affixing zeolites to materials such as paper or fabric, which has
limited the fields in which they can be used.
Rengo has carried out research and development, including that related to paper manufacturing, for many years, and has successfully
crystallized zeolite inside the wood pulp densely. Rengo has commercialized the resulting product as the high-performance pulp.
Cellgaia preserves all of zeolite's exemplary functions while maintaining the shape of the fibers. It can be applied to many types of fiber
products such as paper, nonwovens, and cotton. The performance of this product can also be adjusted easily according to desired functions.

Polyacrylamide-Based Surface Strength Agents Appropriate for Low Basis Weight Paperboard
Shouko Sato
Paper Chemical Business Division, Seiko PMC, Co., Ltd.
Recently, the production of lower basis weight grades of paperboard is progressing for environmental impact reduction, energy saving, andcost reduction in papermaking industry. Paper strength properties generally tend to decrease as the basis weight is reduced. To compensate
paper strength of low basis weight paperboard, dry strength agents are applied. The combination of internal and external application methods isneeded to efficiently increase the compressive strength. Preventing buckling and reinforcing interfiber bonding were important factors for
improving the compressive strength. The external application could be more effective to prevent buckling.
The simulation of relationship between penetration depth of PAM and bending stiffness of paper was carried out. The optimal penetration
depth existed for maximum bending stiffness. To achieve the optimal penetration depth of PAM, molecular design of PAM for external(surface) application was conducted. PAM with the branched structure, high molecular weight, and low viscosity showed the best performancefor compressive strength.

Toward Production of Bioethanol Using Pulp Rejects from Kraft Pulp Mills as Raw Materials
Masanori Kishino, Ken Orihashi and Akira Harada
Forest Products Research Institute, Hokkaido Research Organization
Qualities of 6 kinds of pulp rejects from kraft pulp mills in Hokkaido were investigated as raw materials for production of bioethanol. The
rejects were found to contain more than 50% cellulose, which is very susceptible to enzymatic hydrolysis to glucose, and below 10% acidinsoluble lignin. Although 7-20% of the rejects, in particular with a big particle size, remained as residue, the rejects were hydrolyzed withcellulase to give glucose in over 50% as glucan on the rejects and over 90% on the glucan of rejects. The hydrolyzed solutions were fermented
with yeast to give ethanol in more than 80% on theoretical yield.
In addition, the rejects were hydrolyzed with cellulase for each particle size. Although the rejects in 2-4 mm gave glucose in a 56% yield on therejects for 72 h of hydrolysis, the rejects in below 2 mm gave glucose in a 60-70% yield on the rejects for 24h. This result suggested that theyield of glucose from the rejects increased by decreasing the particle size into bellow 2mm. The rejects as raw materials contained more than
50% of the rejects with a size of over 2 mm. Then, defibrillated rejects with laboratory blender, which contained less than 3% of the rejects witha size of over 2 mm, were prepared, and hydrolyzed with cellulase. As a result, the yield of glucose from the defibrillated rejects increased byover 10%, and its residue decreased by over 15% compared with those from untreated and washed rejects.
In conclusion, the pulp rejects from kraft pulp mills were suitable as raw materials for production of bioethanol.

Paper Business Revitalization Plan and Production System Restructuring Following the Great East Japan Earthquake
Jun Usami
Finishing department, Ai-mate Inc., Nippon Paper Group
Nippon Paper Industries' Ishinomaki Mill was in crisis due to complete devastation by the Great East Japan Earthquake of March 11, 2011.
Following the company’s Paper Business Revitalization Plan, all six papermaking machines together with the two coating machines were in fulloperation within just one and half years.
Reconstruction began with debris removal, followed by reconnection of the power supply, and finally the restarting of the production line. No
one had experience of rebuilding after such extensive damage, so clearing up, selecting which parts could be saved, or how equipment could be
rescued, and dealing with components that had been immersed in sea water, all had to be done by trial and error.
When it came rebuilding the finishing section, in order to establish a more efficient process, it was possible to introduce procedures tominimize the need for paper defect inspection. Such a “No Screening” system has been a goal at the mill for more than ten years.
At the same time, in reconstructing the mill, PPC (plain paper copier) facilities were introduced as a new business at Ishinomaki mill,according to Nippon Paper Industries’ plan to downsize the domestic paper business to meet demand.
Inexperienced operators were trained at another mill for three months, and then, together with the experienced operators, on the new facilities
when they were started.
However, even though reconstruction has been fully completed, we will continue to struggle with problems such as rust from seawater, land
subsidence caused by the earthquake, further reconstruction of the finishing section for more efficient operation, and the early stabilization of
the PPC facilities

LeanE ™ - New Approach toward Energy Saving
Masaharu Menjo and Akifumi Hatta
Sales Department, Metso Paper Japan Co., Ltd.

Mechanical pulping requires huge amount of electricity during its operation. However, the pulp properties produced by mechanical pulping
are attractive for several light weight paper products, e.g. newsprint. Paper mills have been always attempting to reduce energy consumption forthe mechanical pulping and there are still requirements and expectations toward energy reduction from our customers. For utilizing the TMP
lines with more efficiency, Metso Paper are providing a new approach toward energy saving, LeanE ™ concept; Experts from Metso Paper visit
paper mills and audit whole TMP lines during their operation. By collecting and analyzing the actual production conditions, we finally propose
the best solution for the energy saving to our customers.
LeanE ™ concept consists of newly designed and developed equipments, such as screw feeders, mechanical vapor separators, refiner segments
and gap sensors. By replacing existing equipments with new ones, energy consumption can be reduced without deteriorating pulp quality. Somenovel idea for energy saving (for example, refining with low consistency and increase of refiner number) are also included in LeanE ™ concept.
Several paper mills already experienced LeanE ™ concept and they are satisfied with the results of energy reduction. Not only for TMP lines,
LeanE ™ concept can be also applied to kraft-pulp production line and certain amount of energy consumption was successfully reduced atseveral paper mills. In this paper, the basic information and actual examples of LeanE ™ concept are to be introduced.

Metso Automation K.K.
When quality control is concerned, the focus is often on the paper machine. However, the quality potential for a paper machine is always set
before it in the pulp mill and stock preparation area. Correcting stock preparation upsets at paper machine is already too late. To put it simple,
the paper machine merely forms the sheet and removes the water, whereas everything else is done at furnish preparation.
This paper will present the measurement and optimization possibilities in holistic quality management at paper machine and present an
example case for end product quality management by means of optimizing stock preparation area.

Competition among the process industries has become extreme, and to survive from such competition and to lead it to the 21st Century, it has
become obviously necessary for business and control information to make rapid and exact decisions by rich experience and state of art
technologies.
It is also inevitably required for DCS to have such functions as virtual security to protect system from hacking and virus, reducing alarms,
integration with other systems and single windows, as evolving opened system and IT technologies.
Current issue on DCS is how to broad to perform operations safety and effectively as reducing load for each operator of the system.

Development Background and Field Cases of Color Surface Inspection System (MaxEye.Color)
Masahiro Suzuki
FUTEC Inc.

FUTEC has delivered over 7,200 sets of surface inspection systems to various markets including the plain sheet material markets such as paper
and pulp, film, metal foil, non-woven fabric and printing markets such as offset printing, flexo printing and gravure printing since 1978.
A sheet surface inspection system, equipped with the monochrome line scan cameras, uses inspection object’s contrast and shape data for
defect classification. Therefore it makes difficult to classify the defects by color.
Another reason for the difficulty of defect classification by color is that theconventional color line scan camera (drive frequency: 40MHz) is not capable of having enough MD resolution for clear image.
Now, FUTEC has developed a new surface color inspection system,“MaxEye.Color”, using high-speed color line scan camera technology witha drive frequency of 80MHz.

Three main features of this system are: (1) a clear color image of defect, (2) an intuitive color defect classification setting, (3) a real-time color
defect classification.
This system enables operators to see sharp, clear color view of defects to determine
the cause of defects in early stage of production.
Furthermore, it carries out the automatic defect classification for color defects only by using real time processing function. This function
contributes to the operation efficiency by supporting operators’ checking process.

From Rag to Wood: The Review of the Technologies of Producing Pulp
from Wood (PartⅠ)
Kiyoaki Iida
In Europe, rag was a main pulp source in paper making until the midst of the nineteenth century. As the demand of paper increased in theindustrial revolution, new pulp source had to be developed, and some visionaries thought that wood would be able to be an alternative. So, thework to produce pulp from wood started, and major pulping processes, ground wood, alkaline (soda and kraft) and sulfite processes, wereindustrially established in such a short period as about 50 years. As pulp became affluently available, paper was widely used and helped develop
intellectual and social activities. In some sense, the technology of producing pulp from wood is as important as the invention of paper 2000
years ago, and helped the cultural development of mankind in the twentieth century.
In the first half of this paper, the history of producing ground wood pulp, and soda and kraft pulp was reviewed. In the latter half of this paperthat will appear in the next volume, sulfite process was reviewed. Then, how those technologies influenced the cultural development in thetwentieth century was discussed.

Experience in Australian Paper as the First Representative
Mitsuhiro Sugino
Production Dept., Technical & Engineering Div., Nippon Paper Industries Co., Ltd.

In 2009, I was transferred to Australian Paper as a Nippon paper representative because Australian Paper (hereinafter referred to as AP)
became a member of Nippon Paper Group. During my stay in Australia, I tried to introduce some of Nippon paper’s ways into AP and most ofthem were accepted by AP management albeit, after much discussion and some minor modification to ensure alignment with their Australianculture.
In terms of the life in Australia, it was exciting for me because it provided me with an opportunity to experience another culture and to makemany friends. I also had a chance to become a member of Latrobe International Exchange Committee and was in charge of Sister City Day
Festival etc. From a globalization perspective, to know and understand another culture, their language and their way of thinking, was very
important and rewarding for me and I believe this will be of benefit to me in my future roles with Nippon Paper.

Research Report
Characterization of Refractory Organic Matter in Pulp and Paper Mill Effluents
Masayuki Watanabe, Keiko Fujita, Hiro Iwata, Yutaka Nuruki, Kazuko Watanabe, Miyuki Nakagawaand Hitoshi Okada
Japan Pulp and Paper Research Institute, lnc.
The quality of wastewater from Japanese pulp and paper mills has been recently improved, due to regulation of effluent standards which has
been stricter since the Water Pollution Control Law was enforced in 1972. However, it has not attained yet in some mills that the level of COD(Chemical Oxygen Demand) of the wastewater becomes below the environmental standard. Accumulation of refractory organic matter has
been pointed out as a new problem especially for a part of the closed water area in spite of regulation of total emission. Japan Pulp and Paper
Research Institute is researching this problem.
As the first step of this theme, the characterization of the refractory organic matter was studied. Dissolved organic matter in wastewater was
fractionated into five fractions; hydrophobic acid, hydrophobic neutral, base, hydrophilic acid, hydrophilic neutral. Based on measurements ofthe degradation rates of the fractionated components, it was confirmed that the most refractory matter was fractionated into the hydrophobic
acid.
Furthermore, we compared softwood and hardwood kraft pulp (KP) bleaching drainages. Softwood KP bleaching drainage was more resistantto decomposition than hardwood KP bleaching drainage, and contained the hydrophobic acid in a higher ratio. In addition, the hydrophobic
acid in softwood in hardwood KP bleaching drainage.
In order to investigate the source of the hydrophobic acid, the each process drainage was fractionated as well. As a result, the maximum sourceof the hydrophobic acid was KP bleaching process. Pyrolysis GC-MS analysis of the hydrophobic acid of bleaching drainage indicated thatlignin was a major composition of the refractory organic matter.

Relationship between Paper and our Environment-Aiming to the Noble Use of WoodsKeiichi Nakamata
Environmental Management Division, Hokuetsu Kishu Paper Co., Ltd.
Paper is a material that supports our life and culture. The raw materials of paper are woods which are known for sustainable resources. Paper
making companies in Japan have constructed a system to verify the legality and sustainability in utilizing woods. Taking the example ofhardwood, using the hardwood from Satoyama as pulp for paper making contributes to the conservation of Satoyama. In addition, the use ofplantation hardwood from overseas has increased forest area and promoted local employment.
Today, in order to activate the Japanese forests, it is necessary to increase the use of domestic woods. Japanese pulp and paper industry is thebiggest forest-product industry in Japan, using about 40% of the domestic woods, and the forestry's base in Japan.

Fine Particulate Matter (PM2.5)-Generation and ControlKazuhiko Sakamoto
Center for Environmental Science in Saitama
Ambient fine particulate matter (PM2.5) has an adverse effect not only on human health such as increase in the death rate, but also on qualityof life by deteriorating level of visibility and spoiling scenery. An air quality standard for PM2.5 with diameter less than 2.5 µm has been newly
constituted in September 2009 in Japan. Although PM2.5 concentration has been steadily decreasing, achievement of its air quality standard is
not easy especially in urban area. PM2.5 consists mainly of primary particles emitted from various combustion sources and secondary particles
generated from gaseous precursors in the atmosphere. In this report, the current state of PM2.5 in South-Kanto area and future researches
required in order to reduce ambient PM2.5 concentration are described.

Masahiko Aoki
Acoustic Solution Division, Nittobo Acoustic Engineering Co., Ltd.
At factory or plant, sometimes the low frequency noise, which has components less than 100Hz, becomes a serious problem together with thenoise in ordinary frequency. It is known that the countermeasure of low frequency noise is more difficult than the noise in ordinary frequency.
In this article, basic knowledge of the low frequency noise problem is summarized. Also the noise countermeasure techniques which areapplicable for the low frequency noise problem are introduced.

Outline and Experience of Anaerobic Wastewater Treatment System

Atsushi Nakano
Research & Development Dept.,
Sumitomo Heavy Industries Environment Co., Ltd.
Anaerobic wastewater treatment system can make energy from organic pollutants contained in wastewater. In granular sludge bed, anaerobic
bacteria convert organic matters into biogas composed from methane and CO2 in anaerobic environment. Heat or electric power is produced
from methane. And also this system can reduce energy consumption and running costs compared with activated sludge system.
In this paper, basic mechanism of anaerobic digestion, and experiences of actual operation of anaerobic wastewater treatment system aredescribed.

Recent Progress in Treatment of Low-Contaminated PCB Waste
Yo Osada
Japan Industrial Waste Management Foundation
Electrical machinery, such as transformers or capacitors, being contaminated by small amount of PCB was found in 2002 in Japan. The
number of the units is estimated as almost 1.6 million. To promote the appropriate treatment of the PCB waste, the Ministry of Environment
implemented a certification system for businesses detoxifying the waste using sophisticated technologies from 2009. At present, 10 operators
being certificated under the system and one operator approved by a local authority are treating the waste by firing.
However, since the present capacity is still insufficient to the huge amount of the waste, effective measures are to be implemented to increase
the facilities or to materialize new solutions like washing process.

countries, namely, Mongolia, Cambodia, Lao PDR and Vietnam. The paper also discusses international support mechanisms for nationallyappropriate mitigation actions (NAMAs), which developing countries are encouraged to develop and implement within the framework of theUnited Nations Framework Convention on Climate Change (UNFCCC). In this context, the paper analyzes business opportunities of Japanesecompanies in the region, possibly with the use of the Joint Crediting Mechanism (JCM) of the Government of Japan.

POD Business Growth in Social Media Arena
Harunori Sugita
Production Services Sales and Marketing
Fuji Xerox Co., Ltd.
In the process of expanding Social Media Services in Japan, the value of POD services should be diversified into mainly two directions while
retaining its basic concept “on demand time, on demand place and on demand volume”
The first direction should be super centralized POD services in line with Big Data management services expanding with SNS, in which POD
services would be required highly integrated, seamless workflow with higher performance of inkjet or dry toner printing products.
The second one should be super decentralized POD services supporting community building businesses increasing with SNS, in which POD
services support the same contents and expressions rather than variable information by people. There should be increasing demand on handy
and small size of POD systems not only in printing services sites but also office copier printers and public print services such as convenience
stores or city halls.
These two trends are important to view the future development of materials with POD and more spaces are existing to grow.
In this seminar I also touch on what we call “image recognition cloud sevices” that connect paper value with SNS easily. Fuji Xerox has justreleased “Sky Desk Media Switch” service which can connect virtual information such as home page or video clips with paper media through animage recognition service application uploaded into smart media terminals.

From Rag to Wood: The Review of the Technologies of Producing Pulp
from Wood (PartⅡ)
Kiyoaki Iida
Following the Part I, the development of sulfite pulp is reviewed. Though GP and alkaline pulp became available, rag pulp was still a main
source for fine paper. Scientists and entrepreneurs were interested in sulfite process as an alternative, and research work was carried out
worldwide in technologically developed countries like America, several European counties and England with frequent information exchanges
among them. When the technology was commercially established, there was a case representing such operations in which a certain log producer
in Canada bought the license and the technical support from England, imported lime and sulfur from Scotland and Spain respectively, exported
his pulp to America and paid the royalty to England.
As sulfite pulp and GP were at hand, the amount of paper produced accelerated. The society, which was getting affluent after the industrial
revolution, could afford to use it for exchanging information more efficiently, which further increased the demand of paper.
The technology of producing those types of pulp developed since the mist of the 19th century surely contributed to the development of humanculture in the successive generations..

A Calculation Method to Evaluate the Control Effect by PLS Regression Analysis− How Should We Evaluate the Real Control Eﬀect? −Yoshitatsu MoriCore Technology Laboratory, Oji Holdings Corporation
In the pulp and paper manufacturing process, numbers of material properties and end product qualities are changing steadily with time.
Therefore it is considerably difficult to judge the variance of the production cost or the improved effect etc. through the operation data properly
and fairly, because of their disturbances, when they are so tiny amount.

This paper describes a new method to evaluate the effect of the production cost and control effect etc. more accurately when a new control
function was introduced or when process operation methods were changed for some purpose in the production processes.
Here, as an example, a case of a pulp bleaching process was taken up.
The proposed method is follows:
At first, find out the reliable multiple linear regression equation by using statistic analysis PLS (Partial Least Squares) regression method, forexample, between the production cost as dependent variable and some primary explaining variables relates to the bleaching process. As it is wellknown, because the PLS analysis result is superior to the common regression analysis by MLR (Multiple Linear Regression) method in thestability and reliability. Sometimes, the regression coefficients calculated by MLR are tending to be inappropriate by the effects of over fitting or
their collinearity.
Next, to get rid of the random variance and disturbance effects, correct and compensate the targeted “production cost” appropriately by“approximate linear correction method” so as to equalize the manufacturing conditions and incoming and outgoing material properties,
utilizing the regression coefficients that were obtained by PLS regression model in advance.
As a result, it become possible to judge the control effect fairly and acceptably, even if the variance of the production cost is tiny change or theeach explaining variable’s operating condition levels were changing intricately with each other.
