As a member of the Japan Responsible Care Council (currently the RC Committee of the Japan Chemical Industry Association), the Sanyo Chemical Group has established a Management Policies Concerning Responsible Care (RC) and conducts RC activities. We are also engaged in environmental management efforts in line with an Environmental Action Plan that includes priority actions and targets.

≫ Management Policies Concerning Responsible Care (RC)

Responsible Care

Policy

The policy adds “We will strive for perfection in safety and harmony with the environment, which is the first required mission in society" to our Company Mission and “We shall proactively take initiatives to conserve the environment and prevent accidents and disasters as crucial requirements for the sustainability and activity of our business" to our Code of Corporate Ethics.
We are also taking concrete actions in line with our CSR Guidelines, which call for reducing environmental impact, contributing to the environment and improving living conditions as a focus of product development, and conducting sustainable purchasing.

Management System

Management system

The Responsible Care Dept. of the Responsible Care Division oversees all environmental protection activities, while the Products Evaluation Dept. is in charge of chemical and product safety activities and certain logistics safety activities. We had used the environmental management system (ISO14001) as a tool for RC activities promotion. However, as the company has internally established a system to build a management system according to ISO requirements and continuously promote improvements, we have determined that we can operate the system sufficiently on our own, and we relinquished ISO14001 certification for all of our domestic business sites in FY2020. For our overseas business sites, we will continue to maintain ISO14001 certification. In addition, our quality management system (ISO9001) has been certified both in Japan and overseas (San Chemical Co., Ltd. will also relinquish its ISO9001 certification in FY2020).
We will also continue our RC (safety, health, environment, and security) audits of domestic factories and research laboratories, which are conducted during annual site visits.

Environment, safety, and accident prevention investment

To conserve the environment and ensure safety, we continue to invest in environmental measures as well as in safety and disaster prevention, including industrial accident prevention, earthquake countermeasures, and 3Ds (Dirty, Dangerous, and Demanding jobs) improvements.
In FY2023, environmental investment totaled 250 million yen and safety/accident prevention investment was 720 million yen.

JEPIX* environmental efficiency indicator

We significantly improved environmental efficiency compared to FY2005 by reducing atmospheric emissions through measures taken in FY2005 to address ethylene oxide emissions, and in FY2012 to address propylene oxide emissions.
In FY2023, we further improved environmental efficiency from the previous fiscal year by reducing emissions of greenhouse gases and hazardous air pollutants.

Environmental efficiency (JEPIX) (domestic sites)

Environmental efficiency (JEPIX) (domestic sites)

Calculated using the JEPIX Simplified Calculation Sheet Ver. 2.0, which is available at JEPIX website (http://www.jepix.org)

  • Japan Environmental Policy Priorities Index
    Environmental performance is evaluated by multiplying the load values of GHGs and hazardous air pollutants by a weighting coefficient indicating the degree of impact of each, and finally quantifying it as a single index called an Environmental Impact Point (EIP).
    Environmental efficiency is EIP divided by value added. The smaller the total environmental impact, the better, and the greater the environmental efficiency.
