Message from the President
Frequent natural disasters have struck many parts of the world in recentyears. One of the significant factors in such phenomena is global
warming. Reports state that an increase of one degree in the average
global temperature raises the risk of extreme weather, such as torrential
rain, and an increase of two degrees raises the number of species thatwill become extinct due to their inability to cope with these environmental
changes.
To prevent such progress of global warming, society as a whole musturgently reduce greenhouse gases and protect the forests.
Given this situation, the roles of companies, as members of society,continue to expand. In response, the Denyo Group is working toincrease its eco-friendly products such as those equipped with anautomatic engine stop system to reduce CO2 emissions and productswith an environmentally friendly base that minimizes oil spillage outside
the product in the event of oil leakage. We have also been installingenergy-efficient facilities especially at our production and development
bases and are actively promoting efforts to reduce CO2 and wastematerials through 3R activities, tree planting, and other initiatives.
All members of the Denyo Group will continue to earnestly addressenvironmental issues to preserve our precious plant Earth in a safe
condition for the future and contribute to building a rich society.

● Lithium-ion Battery Welder

An engine compressor is a power source that isindispensable in civil engineering and construction sites that
require a supply of compressed air. We are working toincrease the engine compressor models equipped with anenvironmentally friendly base.

Battery welders are environmentally friendly products that allowfor indoor use without discharging exhaust gases and without
creating stress in the surrounding area by making engine
sounds. We have mounted lithium-ion batteries to the battery
welders to create a new line, BDW-150Li, with a higher
environmental performance.

With the environmentally friendly base integrated into the main
unit of the compressor, the product minimizes fuel or engine
oil spillage outside of the product in the event of leakage bycollecting the leaked fuel or oil in the environmentally friendly
base at the bottom of the main unit. It can be easily usedeven in locations such as riversides or ports where
installation standard is strict.
DIS-60LBE has an environmentallyfriendly base, yet is extremely
lightweight with a dressed engine
mass of 330 kg, which allows fortransportation on a light truck. It isalso environmentally friendly in thesense that it reduces the CO2
emissions associated with its
transportation.

DIS-60LBE

The use of lithium-ion batteries extends the battery life to morethan seven times the life of lead batteries, achieving only 10%
degradation of the batteries, even after repeated charges anddischarges 4,500 times. This reduces not only the replacement
work, but also the amount of used batteries that become wastematerials.

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 FY2016 were 4,925 tons, an increase of 1.5% from the FY2012 levels. After the Great East Japan Earthquake, theconversion coefficients to CO2 emission increased along with the increase in consumption of thermal power generation, numericvalue has worsened compared to FY2012, but power consumption before conversion to CO2 emissions coefficients decreased
16.9% from the FY2012 levels. The amount of the consumption of fuels also decreased 19.8% from the FY2012 levels.
We will continue to implement initiatives to cut CO2 emissions during FY2017.

We manage and process solid waste appropriately and in compliance with all laws andordinances.
In FY2016, we discharged about 311 tons of industrial waste, down by 21.3% per
output compared to the FY2012 levels, which is far above the target.
We are also working toward to implement initiatives to reduce a certain amount or moreof Solid Waste stably.

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
the environment 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 for Production Base
●Green (Plant) Curtains
At the Fukui Plant, we create green curtains (curtains made ofplants). A green curtain blocks the strong summer sunlight andreflects the infrared rays that cause heat, which helps to maintain a
low temperature inside.
The plants also remove the heat from the surrounding air bydispersing the water ingested by the roots and stored in the stems
from the leaves, which helps to reduce the use of air-coolingfacilities such as air-conditioners. Green curtains are visuallyrefreshing and prevent heat accumulation in the walls of the building,which also helps to ease the heat island effect. From next year, wewill expand the areas covered with green curtains as part of ourincreased energy-saving efforts.

Green curtains made of bitter melons● Cherry Tree Planting Activities
At the Shiga Plant, we planted cherry trees on thepremises, which already flowered with beautiful
blossoms in the spring of this year. We will expand thetree-planting areas this year and carefully nurture theplants for the local residents to enjoy. The Denyo Groupwill continue to actively plant trees and other greeneryand do cleaning activities to maintain the workenvironment.

Wakasa, Fukui Prefecture
Students from Mikata Junior High School in the town of Wakasa,
where our Fukui Plant is located, visited our Tokyo head office aspart of their company visit program. They exchanged opinions with
our employees from Wakasa about what they could do to improve
Wakasa’s future and protect the town’s beautiful nature.
Encouraged by the variety of ideas provided by the junior highschool students who will lead future generations, we are committed
to continuing business activities that are in harmony with theenvironment in an effort to contribute to further growth while
protecting the nature of Wakasa, home to our production base.
