Emission･management of materials under 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 amount of chemical substance emission depends significantly on the production volume just as the amount of CO2 emission and discharge of industrial wastes do likewise. Both total emission and transfer amounts of substances subject to PRTR (Pollutant Release and Transfer Register) declined due to the global economic slump triggered by the economic crisis in 2009 but turned to an increase as business activities started to pick up. However, with the reduction of VOC (Volatile Organic Compound), such amounts in FY2012 dropped to FY2009 levels. The amounts for FY2013 decreased about 7% on a year-onyear comparison with FY2012 due to further improvement efforts.
Initiatives on air pollution prevention
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 (due to decreased use of paint in the bridge business after announcement of business withdrawal) and Ayase Factory (emission gas treatment facilities commissioned). FY2013 posted further reduction of 20% due to paint gas emission facilities and decreased use of paint and thinner.
