Initiatives to Reduce Environmental Impact

Protection of the Atmospheric Environment

Boiler Emissions Countermeasures

At the Yokkaichi Plant, which generates its own power, we installed flue gas desulfurizers to reduce emissions of sulfur oxides (SOx). We also substantially cut emissions of nitrogen oxides (NOx) by installing burners with low NOx emissions and denitrification equipment. SOx emissions declined in FY2013 as a result of the change in the operation of the boilers at the South Joint Power Plant, which provides energy to the Kashima Plant. JSR will continue to adopt the best emissions reduction technologies and will continue to make improvements.

Regarding PRTR

PRTR*1 Activities

The PRTR Law*2 was enacted in July 1999, and enforced in March 2000. Accordingly, since FY2002 we have been required to report PRTR results. The Japan Chemical Industry Association prioritized PRTR and implemented it ahead of other industries in FY1996; the scope of its survey has increased each year since then. As a member of the association, JSR will implement the survey on a continual basis.
The FY2013 results in accordance with the PRTR Law are detailed below.
Due to a revision of the PRTR Law, in FY2011, Class 1 Specified Chemical Substances subject to reporting requirements increased from 354 to 462 substances.
*1 Pollutant Release and Transfer Registers (PRTR): A system for registering the emission and movement of environmental pollutants
*2 PRTR Law: Law Concerning Reporting, etc. of Releases to the Environment of Specific Chemical Substances and Promoting Improvements in Their Management

Initiatives for Reducing VOC Emissions into the Atmosphere

JSR has long taken measures to reduce atmospheric releases of chemicals, but the FY2005 amendment to the Air Pollution Control Law expanded application to all volatile organic compounds (VOCs). VOC is a general term for organic compounds that easily turn into a gas state when exposed to air. VOCs are believed to be one of the sources of suspended particulate matter and photochemical oxidants, which may have adverse effects on health.
To reduce VOC emissions, five dried-synthetic rubber waste incinerators were installed at three plants between FY2007 and FY2010. In FY2013, VOC emissions fell by approximately 76% from FY2001, enabling us to reach our target levels. We will continue our efforts to reduce VOC emissions.

Preservation of Water Quality

JSR performs rigorous wastewater management at all of its plants and strives to maintain and improve water quality. JSR is in full compliance with the 6th Total Pollutant Load Control that came into effect in April 2009. We will continue to strictly monitor water quality and strive to further reduce our impact on water supplies while paying attention to changes leading up to the 7th Total Pollutant Load Control that is scheduled to be enforced in April 2012.

Assessment of Soil and Groundwater Pollution

Groundwater (Environmental Quality Standards for Groundwater Pollution) and soil (major items regulated under environmental standards) at all three of our plants are periodically inspected. As in previous years, no problems were found in FY2013.

Asbestos Measures

In accordance with the Ordinance on Prevention of Hazards due to Asbestos, JSR has conducted checks at all of its facilities (office, manufacturing, R&D and employee amenity areas), including those of all Group companies, where asbestos containing materials have been sprayed. As a result, in FY2007, removal and enclosure projects were completed at locations in plants where asbestos was found. In addition, we are investigating the replacement of asbestos containing gaskets with non-asbestos containing types and are progressively carrying out replacements when the safety of their use in production has been confirmed.
In order to accommodate requests from the Labour Standards Bureau of the Ministry of Health, Labour and Welfare to thoroughly inform our employees of various systems, including the issuance of the asbestos-related health care handbook and the provision of special benefits as industrial workers' compensation for bereaved families, we introduced, on our website, the relevant leaflet released by the Ministry of Health, Labour and Welfare.

PCB Management

Polychlorinated biphenyl (PCB) is a highly toxic chemical that does not readily break down and is commonly used in transformers, capacitors, and other devices. JSR has stopped using PCB in approximately 96% of its electrical equipment and strictly stocks and manages PCB in accordance with applicable laws. We also intend to incrementally replace equipment that currently contains PCB in accordance with a replacement plan. Although JSR was initially obligated to complete the processing of all PCBs by 2016 under the Act on Special Measures concerning Promotion of Proper Treatment of PCB Wastes, the deadline was postponed until 2027 due to revision of the act in December 2012. JSR and its Group companies have already completed registration of electrical equipment containing PCB with PCB waste processing facilities. In FY2013 we transported 41units of equipment to processing facilities.

FY2013 Number of devices Oil containing PCB (litter)
Electrical devices Devices in storage (not in use) 129 96,586
Devices in operation 6 6,360
Total 135 102,946

Measurement of Ozone-depleting Substances

In 1994, JSR eliminated all use of carbon tetrachloride. By FY2011, at our manufacturing facilities, we had replaced all the large-scale designated equipment that contained chlorofluorocarbons with that employing chlorofluorocarbon substitutes.

Measures to Cut Power Consumption at the Head Office Building

Power Consumption at the Head Office Building (Compared with FY2011 Level)

The Tokyo Metropolitan Government requires major tenants of a building occupying 5,000 square meters or more in floor area or consuming six million kWh or more of electricity annually to reduce its CO2 emissions under the Tokyo Metropolitan Ordinance on Environmental Preservation.
Although we are not subject to this obligation, we are promoting energy conservation on our own initiative by voluntarily setting a specific power saving target.
In FY2013, as a result of the efforts specified below, our power consumption decreased by 18% compared to average consumption from the base years.

Power Saving Target for the Head Office Building

An 8% reduction compared to the average power consumption from the base years of FY2010 and FY2011

Major Efforts
  • Reduced the number of lights and office appliances, such as printers.
  • Visualized our power saving situation, and made our employees become more aware of turning off the power for unused machines and rooms.
  • Implemented the so-called “Cool Biz.”
  • Changed our employees' working schedule to have them begin work and return home earlier than usual on two days per week in July and August.
  • Maintained a proper air-conditioned room temperature that achieves a balance between energy savings and operational efficiency.
