Emission management of materials under the PRTR Law

In accordance with the PRTR Law (the Pollutant Release and Transfer Register Act (the Act on Confirmation etc. of Release Amounts of Specific Chemical Substances in the Environment and Promotion of Improvements to the Management thereof), business entities that handle chemical substances are obliged to manage and report to administrative offices the amount of environmental emission and transfer of chemical substances that are hazardous to humans and ecosystems at each of their business sites. Based on this system, we submit annual reports to the respective administration bodies, and at the same time, use this process to implement continuous management of chemical substances.

The emissions of chemical substance, like the case of carbon dioxide and industrial waste, is heavily affected by the variations in production volume. At the company, both emissions and transfer amount of the materials regulated by PRTR have drastically decreased due to the business integration and other measures taken in FY2012. After FY2012, the amount in question has continued to decrease up to FY2015, but it stayed at almost the same level in FY2016.

We continue to realize planned reduction in the future.

Initiatives on air pollution prevention

拡大

With the revision of the Air Pollution Control Law in May 2004, it became necessary to respond to regulations on emission of VOC, and a reduction of 30% compared to FY2000 on a year-on-year basis was presented as the domestic reduction target by the end of FY2010.

As a proactive approach for the prevention of air pollution, Topy Industries is conducting voluntary measurement of VOC concentration from the facilities generating VOC at our four major factories as well as reviewing action items related to production technologies for the reduction of emission.

In FY2012, VOC emission dropped to half compared to the previous year due to reduction at Toyohashi Factory (due to decreased use of paint in the bridge business after announcement of business withdrawal) and Ayase Factory (emission gas treatment facilities commissioned). In FY2016, VOC emissions dropped further by 13% on year-on-year basis due to shifting of painting materials, curbing in the amount of paint thinner. We keep working on to planned reduction in the future.
