Approach in Manufacturing

For the purpose of "Prevention of Global Warming" and "Effective Utilities of Resources", RISO promotes several activities, which include energy-saving or reduction of excretory products.

Approach to Energy Saving

On-Demand Production System: How it Works

Adhering to the concept of manufacturing products in demand in a timely manner and in required volume, RISO's production departments engage in lean manufacturing operations that effectively use resources and energy.

Also, RISO avoids introducing high-volume, high-speed production facilities at the same time. Instead, when necessary, the Company introduces facilities in a stepwise manner to respond to the exact demand level while developing in-house facilities as much as possible based on its know-how and expertise.

Waste Reduction

RISO promotes 3R(Reduce, Reuse, Recycle) activities to reduce waste generated through its operations. In particular, the Company focuses on the reduction of the amount of waste that is not recycled and is used for landfill.

Chemical Substance Handling Management

Many of RISO's products contain various chemicals, and the manufacturing process also requires such chemicals.

RISO requests each supplier to provide SDS* to verify the characteristics of each substance, including toxicity, handling precautions, storage and disposal methods, in order to ensure proper handling. Based on such investigation, RISO established specific standards to facilitate the safe use and storage of these chemicals.

Moreover, prevention of accidents and hazards is accomplished by educating the employees who handle, store or control chemicals, in addition to establishing applicable procedures. This achieves not only the safety and health of employees, but it also helps preserve the ambient environment.

*SDS (Material Safety Data Sheet)
A safety data sheet (SDS) is a form containing data regarding the properties of a particular substance, provided by the suppliers of such substances containing certain chemicals when they are sold or transferred to another party.

Cutting off PRTR Listed Substances

RISO is investigating the environmental release and transfer of toxic chemicals listed in PRTR*. Based on this investigation, RISO examines the possibility of reducing toxic releases, or switching to alternatives, so that total releases and transfers during the manufacturing process are minimized.

*PRTR (Pollutant Release and Transfer Register)
The PRTR is a system aimed at preventing environmental hazards through control of the corporations that deal with potentially harmful materials. The PRTR is an environmental database or inventory of potentially harmful releases into the air, water or soil. Also included in the database are wastes transferred for treatment and disposal from the site of their production. Corporations do this of their own accord, reviewing such data themselves, reporting to relevant administrative organs or publishing the information.

Green Curtain at Ube Plant Wins Awar

Green curtain

As part of everyday methods toward conserving energy and helping to prevent global warming we cultivate a green curtain at the Ube Plant. The curtain consists of bitter gourd and morning glory vines. The 15m wide by 6.5m tall curtain, which covers the entire south wall of the administrative building up to the second floor, received an award for excellence in the businesses division of the 2013 Green Curtain Contest sponsored by Ube City.

Ube Plant Roof Coated in Heat-Reflecting Paint

Roof with heat-reflecting paint

A variety of capital investments are carried out at our manufacturing sites to raise the energy efficiency of facilities and equipment. This includes introducing heat-reflecting paint for building surfaces to prevent temperature rises caused by the powerful rays of the sun. The paint, which was first applied to the Tsukuba Plant in 2012, has now been applied to the Ube Plant as well.
