Message from the President
Thank you for reviewing the Environmental Report for Denyo Co., Ltd.
I would also like to thank you for your interest in our company. In theinterest of disclosure, we have decided to publish an environmental
report as of this year. I hope the report will hold your attention.
The recent increase in the global population has revitalized production
activities and brought with it bright prospects for global economic
development. However, the impact of production activities on theenvironment is great, global warming being a perfect example, and theglobal environment is now seen as an issue for the whole world. At
Denyo, we recognize that initiatives to solve these problems are a social
mission. As a company, we are pulling together to find solutions while
keeping constant watch over the environment from the development
and production aspects.
Based on our environmental philosophy, we will continue to contributeto a sustainable society by implementing the environmental policies, andwe will strive to improve the value of our products and our company

the risk of environmental pollution through the eco-baseinstalled at the bottom of the main unit to contain leaks.

operate continuously for a long period of time on asingle supply of oil.
Since the engine-driven welder is also equippedwith an eco-base, it supports a broad range ofconstruction work from industrial complexes andpower stations to general construction work.
We will continue to develop eco-friendly productsthat meet the needs of our customers.

DLW-300LSE9 DLW-200X2LS Engine-Driven Welder
The DLW-200X2LS is an engine-driven welder for
two users, which includes an automatic idle-stop
function as a standard feature. When pausing welding
work or work that uses the alternator, the engine is
automatically stopped after a set period of time andwhen operations resume, the engine automaticallyrestarts. Since welders are rarely in continuous use on
the work floor, the automatic idle-stop feature greatly
reduces fuel consumption and CO2 emissions. Denyo
is the first in the world to develop the automatic idlestop technology feature for engine welders (patented).
The function has been highly acclaimed for its impact
on reducing the CO2 emissions that cause global

The automatic idle-stop function and the nonstep e-Mode function in the DLW-200X2LS
contribute to a reduced environmental load bykeeping down fuel consumption, cutting CO 2
emissions and reducing noise levels.

When welding work starts, the non-step e-Modefunction applies variable speed control to the engine
and keeps it operating at the optimum number ofrevolutions. This function reduces fuel consumption

and noise levels during operation.

10 DIS-200 VPS (B) Engine-Driven Compressor
The DIS-200VPS (B) is the first variable pressurecompressor in the industry that allows the operator tofreely set the discharge pressure by inputting settings on
a digital panel. When the required discharge pressure(0.6–1.27 MPa) has been set, the variable pressure
system automatically controls the number of engine
revolutions and capacity according to air volume. The
system optimizes the features of the electronicallycontrolled engine, and the efficiency of the compressor(patented).
As a result, a single air compressor can accommodate
environments that require high pressure and low-pressure
capacity applications, eliminating the need for several
compressors depending on work environment andapplication, and thereby increasing efficiency.
The large-scale high-pressure compressor is also thefirst in the industry to be designated an ultra-low noise
construction machine, adding an element of excellence interms of environmental load reduction.

Global Warming Prevention

Resource Recycling Society Reduce CO2 Emissions

 Reduce Solid Waste

Denyo also endeavors to prevent global warming
through initiatives to reduce the CO2 emissions thatcome with the character of the business.
Disappointingly, CO2 emissions in FY2012 were 5,229
tons, a year-on-year increase of 7.8%. This is due to theimpact of a rise in the CO2 emission coefficients forpower consumption.
We will continue to implement initiatives to cut CO2
during FY2013.

We manage and process solid waste appropriately

In FY2012, we discharged about 289 tons ofindustrial waste, down by 10.9% per output comparedto the previous fiscal year, and we reached the target of
a 2% year-on-year reduction.
We are working toward a new target of cutting thevolume of industrial waste per output by at least 15%
compared to FY2011 levels by the end of FY2016.

Environmental Measures for Buildings
 Green Roof at the Head Office
Based on the philosophy of promoting environmentallysound business activities, Denyo started installing a green
roof at the head office in FY2012. The rooftop garden
provides some control over temperature increases in thebuilding. It also alleviates the heat island phenomenon
and improves air-conditioning efficiency.
When planter boxes are included, the green roof at thehead office occupies 38% (40.88 m2) of the roof area. The
soil is a light-weight artificial soil (Aquasoil) that can resist
the dry summer period. With approximately 20 thriving
species focused on flowers reminiscent of the four
seasons, the garden also contributes to wellbeing.

 Laboratory & Training Center
Construction of the Laboratory & Training Center atSakado, Saitama Prefecture was completed in February
2013.
The building is equipped with many of the most recent
environmental technologies including solar panels and a
mist spray system that uses rain water to cool thebuilding as part of efforts to conserve energy. As a resultof sensitivity to the outdoor environment, including
greening of the premises, the building has achieved thetop S score under the CASBEE* system.
We are also installing a green roof at the Center.
* CASBEE (Comprehensive Assessment System for Built Environment Efficiency) is a system forobjective and comprehensive assessment of the quality of buildings including sensitivity to theenvironment, economical running costs. and comfort of the residential environment.
The assessments are scored on a five-point scale and labeled Excellent (S), Very good (A),Good (B+), Fairly poor (B-), or Poor (C).

Manufacturing Corporation, a Group company in the UnitedStates. The awards ceremony was held in September 2013. TheMVP2 Award is presented by the National Pollution Prevention

15 Bio-indicators to Monitor Water Quality
At the Fukui Plant, treated waste water is held in astabilization pond on the premises before discharging tothe river. The stabilization pond is stocked with carp. By
confirming whether organic life can sustain itself in thepond, we have introduced bio-indicators to monitor thequality of the treated waste water.
By routing the treated water via the stabilization
pond, the risk of releasing polluted water straight into
the river is also minimized in case of a discharge ofprimary waste water.
