Activities of Our Municipal Solid Waste Treatment
Plant Business
A leading company in the industry

1 Plant construction

Since completing Japan’s first fully continuous mechanical waste incineration plant in 1963, Takuma has built more than
350 waste incineration plants in the country, more than any other company in the industry.
We have consistently led the municipal solid waste treatment industry, for example by starting operation of Japan’s firstcombined facility comprised of waste incineration and biogas recovery plants and building numerous high-efficiency wastefueled power plants.
Takuma will continue to contribute to the realization of a recycling-based society as the industry’s leading company.

Stoker-type incinerators
Most Energy from Waste plants use stoker-type incinerators. Takuma has been delivering stoker-type incinerators tocustomers for half a century, allowing us to accumulate a variety of expertise in areas such as stable combustion, exhaust gas
treatment, and waste-fueled power generation.
Based on this well-established base of technological capability, we build and supply highly efficient waste treatment
systems by integrating the latest technologies, for example water-cooled stokers, proactive combustion control, exhaust gas
recirculation systems, and furnace denitration and urea decomposition systems.

From construction to after-sales service
Takuma’s municipal solid waste treatment plant businessconsists of four components: plant construction, primaryequipment improvement, maintenance, and long-term
turnkey operation.
In each area of operations, we draw on technologicalcapabilities and expertise based on our extensive experienceto precisely meet the needs of local governments, regions,and society, allowing us to offer facilities that are
welcomed by their communities.

Recently the Ministry of the Environment has been encouraging the introduction of biogas recovery plants for use withmunicipal solid waste. This is an area where Takuma is helping further lower CO2 emissions with a combined system of
methane fermentation and incineration for municipal solid waste to recover the maximum amount of energy from the waste
treatment and utilize it in high-efficiency power generation. (The system received the New Energy Foundation’s Chairman Award at the FY2014
New Energy Awards.)

3 Maintenance

Implementing high-value-added renovations

Ensuring stable waste treatment

Although waste treatment plants are required to operate over extended periods of time, equipment must be renovatedonce 20 or more years has passed since the plant began operating. In addition, changes in the regulatory environment andsociety sometimes make large-scale renovations necessary.
Takuma draws on the sophisticated heat utilization technologies and energy-saving technologies it has accumulated as aboiler and environmental plant manufacturer to carry out high-value-added and large-scale renovation projects. In this way,
we are able to help extend facilities’ service life while lowering CO2 emissions.

Annual maintenance is essential in order to ensure stable operation of waste treatment plants. However, maintenancedemands both sophisticated technological capabilities and experience, both because waste treatment plants draw on a range ofexpertise and because the manner in which their equipment deteriorates over time varies with the properties of the waste they
process. Takuma takes maximum advantage of its accumulated expertise to contribute to stable waste treatment and long-term
facility operation by developing long-term repair plans, carrying out elaborate site investigations, and then performing
maintenance that has been optimized in terms of both timing and content.

Activities of Our Energy Plant Business—Transforming a variety of biomass resources into fuelTechnologies and experience in using a broad range of biomass fuels
Since its founding, Takuma has enhanced its technological capabilities as a pioneering boiler manufacturer to deliver a
total of more than 600 boilers designed to accommodate a wide variety of biomass fuels in Japan and overseas.
Going forward, we will continue to actively pursue development and improvement of technologies for effectively using
energy in a way that gives priority to both humankind and the planet while simultaneously meeting customer needs.

Social landscape

Takuma is working on facilities that use biomass fuel throughout Japan.
● We have constructed facilities that use forestry-derived

biomass fuels such as thinned timber and waste fromlumber plants and industry-derived biomass fuels suchas plant waste and sludge from manufacturing plants inmany regions.

Hokkaido Region
Wood fuel: 11 plants● We have constructed many facilities in Japan that use

Business
Development

The Great East Japan Earthquake of 2011 threw the safety of nuclear power plants into question and led many tobegin focusing on “renewable energy,” which is characterized by a low environmental impact, as an alternative sourceof energy. Biomass-fueled power generation in particular promises beneficial ripple effects such as redevelopment of
the forestry industry and job creation as companies move to fill needs of fuel procurement, transport, and storage aswell as chip processing and other operations. Compared to solar and wind power, biomass also has the advantage ofbeing able to provide power in a relatively stable manner without being affected by weather. Currently, biomass-fueled
power plants are being planned and built in locations across Japan.

Sales activities from the customer’s
perspective

Planning of biomass-fired power plants has surged due to the effects of Japan’s
feed-in tariff (FIT) program for renewable energy, which entered into effect in July
2012. As a result, our sales departments have been receiving a large number ofinquiries for such facilities.
Our primary focus as we work to accommodate those inquiries is on pursuingsales activities from the customer’s perspective. Since numerous companies fromother industries are entering the FIT business, we work in our daily sales activities
to build trust by addressing the concerns of customers with little experience inplant operation and to offer the best possible proposal for each customer.
Negotiations typically entail considerable difficulty, but I look forward toworking through various obstacles and challenges in an optimistic and constructive
manner while communicating closely with involved parties both inside and outside
the company.

Step grate stoker

Traveling stoker

This combustion method,which derives from waste
incineration technology, canbe used to uniformly burnfuels with different calorificvalues, moisture content,
shapes, and sizes. Anothercharacteristic of this method
is that it requires less power
to operate (known as facility
power) than other types.

With a traveling stoker, fuel isdistributed in the furnace sothat longer combustion times
are secured for fuel withlarger volumes. As with astep grate stoker, combustion
is comparatively gradual, andthe system can accommodatea wide range of fuels withdifferent calorific values, moisture content, and shapes.

Bubbling fluidized bed

Circulating fluidized bed

Since sand that has been
fluidized by high-pressure air
burns away the surface of thechips, little unburned fuelremains, making high boiler
efficiency a characteristic of
fluidized bed systems. They
can accommodate a variety ofdifferent types of fuel, including fuels with high moisture
content.

Heated, fluidized sand burns
fuel as it circulates, keeping
temperatures inside thefurnace uniform to enablestable combustion. Since little
waste remains unburned,
boiler efficiency is high, andthe system can accommodate
a broad range of mixed fuelswith different caloric values.

Activities of Our Water Treatment Plant Business
More than 50 years have passed since Takuma entered the water treatment business. To date, we have helped improve thewater environment by building water treatment facilities. Recently, the industry has been called upon not only to improve thewater environment, but to reduce the amount of power that treatment equipment consumes and to create energy fromsludge.
This section introduces some of Takuma’s recent initiatives, using a sewage treatment plant as an example.

3 Sludge-fueled power

2 Rapid filtration facility
A sand filtration facility removes even smallersuspended particles in water that has alreadypassed through the reaction tank and sedimentation basin. This type of facility is necessary when
the river into which treated sewage is discharged
is subject to strict water quality requirements orwhen the treated sewage will be reused.
Moving-bed sand filtration facilities, which are a
specialty of Takuma’s, deliver energy and spacesavings along with stable performance. To date,
we have delivered more than 2,500 such systems
throughout Japan.

In this project, we installed a newfiltration facility capable of treating
about one-third of the entire
throughput of the Edagawa Sewage
Treatment Plant (about 30,000 m3
per day). This type of system isinstalled inside a tank, so it’s difficult
to picture what it looks like, but acreative approach is required in order
to fit it into the available space since
it has a large number of components.
I was responsible for the construction process as the project’s field
representative. We completed thatprocess without incident in about six
months thanks to support from thecustomer and numerous other involved parties. I hope that throughthis construction project we will beable to help protect water quality
where treated sewage is discharged.

system and introduced advanced
treatment capable of removing
nitrogen and phosphorus. The
latter can be expected to improve
the quality of treated sewage, toprotect water quality where treateddischarge is discharged, and toprevent eutrophication, whichcauses phenomena such as red
tides, in Osaka Bay. It is our hopethat the facility in whose designand construction I was involved will
operate in a stable manner over thelong term and play a useful role inprotecting the water environment.

Sludge, which is a byproduct of the sewage
treatment process, contains a large amount ofenergy. As a result, it has been attracting attention in recent years as a type of biomass.
Takuma harnesses its core incineration andboiler technology to make effective use of sludge
as fuel for power generation to create electricity.

Activities of Our Overseas Business
Biomass-fueled power plant business in the Southeast Asian market

Overseas Energy from Waste plant business

The biomass-fueled power generation boiler business in Southeast Asia is an essential part of any discussion of Takuma’s
history. We have delivered more than 370 biomass boilers to customers overseas, and we have an especially extensive trackrecord since 1959 of delivering boilers fueled by bagasse (fiber remaining after sugarcane is crushed) in Thailand, where wehave a local subsidiary. Takuma has supported the Thai sugar industry for many years.
As the feed-in tariff program becomes increasingly well established in various industries, a growing number of customers
in Thailand are looking beyond simply gaining a source of power for plant operation and instead opting to construct boilers
with the goal of using 10 MPa/520°C class boilers that operate at comparatively high temperature and high pressure levels toactively generate electricity for resale to boost their income. In this way, demand for this type of boiler facility is expected tocontinue to grow.
Under these conditions, we look forward to helping supply environmentally friendly power from biomass, particularly inSoutheast Asia, by accommodating demand not only in Thailand, but also in neighboring countries such as Indonesia andVietnam with reliable technology and fine-grained customer service based on our extensive experience in the field.

Waste processing problems have been manifesting themselves in countries around the world recently due to the effects of
rapid urbanization, and there have been reports of the adverse effects of burying waste as-is on living conditions, including
soil pollution and fires, especially in developing nations. These countries have embarked on initiatives to resolve waste
processing issues, but the fact remains that they require even more sophisticated waste processing diagnostic expertise,advice, and guidance.
Takuma has deep experience and an extensive track record that together make it a market share leader in waste
incineration and processing equipment in Japan. The photograph below depicts a plant that we delivered in Beijing, China,
but in fact we have delivered plants in nine overseas countries and regions, including China and the UK. Our Lakeside Plant in
the UK and our Gaoantun Plant in Beijing have earned a high level of praise and trust from their respective customers, forexample due to the facilities having achieved continuous operation for more than 8,000 hours a year.
We look forward to taking advantage of our extensive experience to closely exchange information and engage inpartnerships with local stakeholders as we offer optimal proposals that meet the full array of needs using technologicalcapabilities in which we have great confidence.
Apart from plant construction, numerous issues must be addressed in order to resolve waste processing problems,
including methods for collecting and sorting waste, awareness-raising and environmental education, and consensus-building
with local residents. While it takes time to resolve each of these in turn, we are confident that it is precisely by cooperatingwith such initiatives that we can best provide safe, stable plants that inspire pace of mind on the part of people in their hostcountries and communities.
Going forward, Takuma will continue to contribute to environmental protection by pursuing an overseas Energy from
Waste plant business that suits each country and community.
