Message from the President
In recent years, disasters such as floods and heat waves have been increasing inJapan and around the world, and it is reported that the major cause is global
warming. Based on the Paris Agreement on climate change, which came into force
in 2016, countries around the world have begun to take measures against globalwarming.
As a company operating a global business, we, the Denyo Group, believe that weare responsible for dealing earnestly with environmental issues and positively
carrying out activities and developing products that are environmentally friendly.
Given this situation, we have been conducting environmental activities continuously
based on the environmental management system ISO 14001, and we have been
introducing energy-efficient facilities, promoting the 3Rs and greening, and making
other efforts to reduce CO 2 emissions and waste materials in our business activities.
On July 2 this year, we also celebrated the 70th anniversary of our founding. Over
these 70 years, numerous environmental issues have arisen, such as noise andexhaust gas, and we have been addressing each of them. As worldwide population
increases and the economies of developing countries grow, it is expected that wewill see many more environmental issues in the future. We will continue to address
diversified environmental issues seriously, contribute to achieving a sustainable
society, and strive to celebrate our 80th, 90th and 100th anniversaries.
We would greatly appreciate your continued understanding and support.

October 2018

Eco-Friendly Products
Developing Products with High Environmental Performance● Welding machines with an automatic idling stop function● New Simul Generator

While there has been greater interest in preventing global warming
in recent years, eco-friendly engine welding machines with anautomatic idling stop function are highly rated. This function isdesigned to stop the engine automatically when welding work issuspended and reduce CO2 emissions, which are causes of globalwarming.
If the idling state exceeds the set time during the welding work, theengine will stop automatically. This will save fuel and reduce CO2
emissions significantly. To resume the welding work, the welding
materials simply need to be knocked with the welding rod twice,
and then the engine will restart automatically.
The automatic idling stop function of engine welding machines isthe first such technology in the industry, developed by Denyo.
About 10 years have passed since its debut in 2007, and there are
now seven models with this function. We would like to strive toexpand adoption of the automatic idling stop function andcontribute to the prevention of global warming.

New Simul Generators are now available. These generators enable
you to simultaneously use a three-phase power load, such as
submersible pumps and compressors, and a single-phase load,such as lighting and air conditioners in a temporary office.
Because there is no need to prepare two generators, and it ispossible to respond to needs with a single unit when a threephase power load and a single-phase load are used simultaneously,
the new generators are highly acclaimed for enhancing
environmental performance in terms of delivery and installation.
With the adoption of the unique new winding method, the new
Simul Generators have drastically improved the voltage
fluctuation on the single-phase side compared with conventionalmachines. In addition, the single-phase output has been increased
by about 10%, so it is possible to feel secure in using it moreconveniently.

Global Warming Prevention● Reduce CO2 Emissions
Denyo endeavors to prevent global warming through initiatives to reduce CO2 emissions due to business activities.
CO2 emissions in FY2018 were 4,956 tons, an increase of 4.1% from the FY2017 levels. This is attributable to the fact that theamount of fuel used for heating and clearing snow increased due to the record-breaking snow that hit the Hokuriku areas,including Fukui, in February 2018.
We will continue to implement initiatives aimed at reducing CO2 emissions.

Breakdown of Total Solid Waste*Total for the Fukui and Shiga Plants

We manage and process solid waste appropriately
and in compliance with all laws and ordinances.
In FY2018, we discharged about 242 tons of industrial
waste, down by 4.6% per output compared to theFY2017 levels.
We are also working toward to implement initiatives to reduce acertain amount or more of Solid Waste stably.

In recent years, there have been problems with the depletion of resources
such as petroleum, which are essential for our daily lives, and the shortageof final disposal sites for garbage. The importance of 3Rs (Reduce, Reuse,Recycle) has been increasing.
Denyo implements a range of initiatives to make effective use of limited
resources and minimize the impact on the environment. We will now
introduce some of these activities.
Reduce ／ Reuse
We changed from wooden pallets to iron pallets on the loading
platforms used to transport products and other goods.
The previous wooden pallets became deformed after only one use, andthey were disposable. We changed to iron pallets, so they can now be
used repeatedly. This has significantly reduced the amount of scrapwood.
RecycleSludge generated in the production process is used as cement
materials, and waste oil is reused as recycled oil by separating oilfrom water.

Managing Chemicals● Managing Chemicals Subject to PRTR
Based on the PRTR Law, we compile and release data on chemicals subject to the PRTR including amounts released into theenvironment or transferred as solid waste.
*A Pollutant Release and Transfer Register (PRTR) is a system for compiling and disclosing data on hazardous chemical substances
including their sources, how much is released into the environment or transferred off-site with solid waste.

Environmental Measures and Community Contribution Activities● Fukui Plant

Completion of the New Cafeteria Building

The construction of the new cafeteria building of the Fukui Plant was completed in March 2018, and it utilizes environmentallyfriendly equipment, such as introducing LEDs for all lighting.
In addition, the basic color of the room is white, and multiple large windows have been installed to take in natural lightefficiently for comfort with a small amount of electricity.
The new cafeteria building has a steel-frame two-storied construction with a total floor area of around 1,258 square meters.
The first floor has a cafeteria that can serve about 220 people, and the second floor has a library, a common room with tatami
mats and a multi-purpose room for employees to enable them to enjoy break time.
Denyo will strive to improve productivity and operational efficiency, and also develop a better workplace environment.

We invited our employees’ families to the Fukui Plant and held a plant tour. This event was held for the first time this year, and22 people of 10 families participated in the event. It was planned and implemented in our hope of showing their families how
they work, which cannot be seen at home, what environment they work in and what kinds of jobs they do.
Family members who participated in the event commented, “I enjoyed experiencing the atmosphere of the workplace andseeing how he/she works,” and “The food in the cafeteria was delicious.” Employees who work at the Fukui Plant alsocommented, “I was pleased to see how delighted my family and the others were, and I would like more people to participate
in the event in the future.”
We held this event for the first time. It met with a favorable reception from the families and it was a good opportunity todeepen their understanding of our work, we would like to continue to hold it in the future.

Denyo has been working on greening andcleaning activities in the areas around ouroperating sites. We call this initiative “GreenClean Activities.”
The pictures show planting work at the Fukui
Plant and cleaning activities at the Laboratory &Training Center.
Denyo will continue to focus on Green CleanActivities in the future, while taking harmony
with nature into consideration.
