Chemical Substance Management

Basic ConceptMinimizing environmental impact through proper control and emission reductions of chemical substances

While chemical substances make people's lives more convenient, they also could have harmful effects on the environment or on human beings. Therefore, we believe that consideration of product safety, occupational safety and health, and environmental impact through proper management of chemical substances is an important responsibility of an enterprise.

Since fiscal 1999, the Sekisui Chemical Group has set and worked toward its own targets for reducing emissions and the transfer of chemical substances in addition to implementing efforts such as the Product Assessment System for Environmental Impact1. and the Green Procurement System2. Periodically we also review chemical substances, in accordance with the establishment and amendment of relevant laws and regulations.

 

1. Product Assessment System for Environmental Impact: A system for assessment of the environmental impact of product development all the way from raw material procurement through manufacture, use, disposal, transport, and all other stages.

2. Green Procurement System: A system of giving priority to choosing raw materials, parts, etc. with lower levels of environmental impact when procuring them.

Controlling VOC EmissionsVOC emissions reduced by 23.5% compared with fiscal 2013 level

In our environmental medium-term plan, we have set the target of keeping VOC emissions pegged to fiscal 2013 levels in Japan and to fiscal 2014 levels overseas. In fiscal 2016, VOC emissions in Japan were reduced 23.5% compared with fiscal 2013.

Alternative fluorocarbons were fully phased out in fiscal 2008.

Preventing Air and Water PollutionManaging gas emissions and wastewater in accordance with regulations

The Sekisui Chemical Group complies with the regulatory values under laws and ordinances for the various types of equipment it uses in connection with exhaust gases and water drainage. We also strive to control the discharge of pollutants through appropriate maintenance and management, including periodic inspections.

Soil SurveysWe completed surveys of all planned business sites

We drew up plans to conduct a self-assessment of soil contamination at our business sites and conducted ongoing surveys. In fiscal 2011, we completed planned surveys of all business sites. Surveys have also been conducted since fiscal 2012 as and when required. This includes at the time of plant closure. In fiscal 2016, conditions did not require any assessments of soil contamination.

 

Disposal and Storage of Devices Containing PCBs and Management of Equipment that Uses Fluorocarbons Properly storing and disposing of devices containing PCBs in line with regulations

Transformers and condensers that contain PCBs are being disposed of steadily, where PCB treatment facilities are available. Machines and equipment in storage that contain PCBs are managed strictly and thoroughly, through means including locked storage and periodic inspection.
Steps are being taken to enhance awareness toward mandatory requirements regarding equipment that use fluorocarbons in accordance with Japan’s Act on Rational Use and Proper Management of Fluorocarbons (Freon Emission Control Act) and to ensure thoroughgoing management including periodic inspection.

 

Response in EmergenciesTraining to respond to unforeseen events that impact the environment

To prevent and mitigate environmental pollution during an emergency, our employees at each business site are trained at least once a year in emergency procedures and communications for a variety of scenarios unique to each business site.
