Environmental Impact and Resource Reduction, and Climate Change Countermeasures / Environment and Safety (Related Data)

1. Protection of the Atmospheric Environment

(1) Boiler Emissions Countermeasures

At the Yokkaichi Plant, which generates its own power, we installed fuel 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. In FY2014, the fuel conversion (from heavy oil to public utility gas) change implemented at the Kashima Plant (Kashima Joint Power Generator) resulted in a reduction of both SOx and NOx emissions, an achievement that was maintained in FY2016.
JSR will continue to adopt the best emissions reduction technologies, and will continue to make improvements.

(2) Initiatives for the Reduction of VOCs*1 Emissions into the Atmosphere

Having set a high voluntary goal for the reduction of emissions of volatile organic compounds (VOCs) by 75% from FY2001 levels, JSR undertook large-scale investment between FY2007 and FY2010 to install five dried-synthetic rubber waste incinerators in three plants. We also carried out meticulous maintenance and management activities, including enhancing the airtightness of release points, improving the working method by adopting a closed system for chemical sampling and preventing leakage from bulbs. As a result, our VOCs emissions in FY2016 were 971 tons (77% reduction as compared to FY2001), in so doing, we reached our internal target. As we ramp up our production volume, we will maintain the level of the current voluntary goal (75% reduction from FY2001) without large-scale investment by ensuring the proper operation of dried-synthetic rubber waste incinerators and finely tuned maintenance and management.

*1 VOCs = Volatile Organic Compounds.

Reference: VOCs reduction targets

  • (1) Air Pollution Control Act (enforced in April 2006): To achieve a 30% reduction in the amount of VOCs released into the atmosphere from the FY2001 level by FY2011 with the effective application of laws and regulations, along with operators' independent activities.
  • (2) Japan Chemical Industry Association: To prevent any further negative impact over FY2011 levels by FY2016.

(3) Measurement of Ozone-depleting Substances

As part of compliance with the Freon Emission Reduction Act established in April of 2015, all businesses that use designated products, including industrial air conditioners, refrigerators, and freezers, must perform basic inspections, periodic maintenance, and create inspection records. A total annual leakage of 1,000 t or more of CO2 must be reported to the acting minister.
For this reason, JSR has created management standards for devices that use freon and has mandated a policy that such devices be managed in accordance with these standards. The amount of freon leakage in FY2016 was 252 t of CO2.

2. PRTR Support

(1) PRTR*2 Activities

Based on the Act on Confirmation, etc. of Release Amounts of Specific Chemical Substances in the Environment and Promotion of Improvements to the Management Thereof, JSR aggregates the amount of designated chemical substances emitted into the environment (atmosphere, water and soil), transferred by manufacturing, or used in the previous year, and notifies the government of Japan of the results. We have systematically implemented a range of measures primarily for substances that are emitted in significant amounts and have a great impact on the environment. Such measures include enhancing the airtightness of substance release sources, rendering substances harmless by incineration, and improving manufacturing processes. In FY2016, as a result of taking such measures, we reduced emissions of the substances designated by the PRTR (287 tons) by 89% from the FY1996 level.

3. 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 7th Total Pollutant Load Control that was put into operation in April 2012. We will continue to strictly monitor water quality and strive to further reduce our impact on water.

4. 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 FY2016.

5. 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. Subsequently, at locations in plants where asbestos was found, we completed removal and enclosure projects in FY2007. 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.
We will continue to act properly to prevent workers engaged in building demolition work from acquiring health problems caused by asbestos exposure in accordance with air pollution prevention laws and asbestos disability prevention regulations.
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 the relevant leaflet released by the Ministry of Health, Labour and Welfare on our website.

6. PCB Management

JSR stores and manages PCB waste in an appropriate manner in accordance with the "Act on Special Measures concerning Promotion of Proper Treatment of PCB Wastes" and subsequently carries out detoxication treatment in accordance with the law.

    • Energy-saving through changes in heat recovery and solvent types across multiple plants
  • (2) Other Technologies to Reduce Environmental Impact
    • Development of solution polymerization manufacturing facilities and a new solvent recovery process (to reduce hydrocarbon emissions into the atmosphere)
    • Development of synthetic rubber manufacturing facilities and dry exhaust systems (to reduce odors near plants and hydrocarbon emissions into the atmosphere)
    • Development of polymerization technologies to combat total nitrogen emissions (measures to prevent eutrophication of ocean waters)
    • Development of environmental technology through more effective use of microbes (to reduce odors near plants and to improve the quality of wastewater)
    • Incineration technology for dry synthetic rubber dry exhaust (measures for harmful atmospheric pollutants)
    • Installation of a sludge dryer system (to reduce CO2 emissions and promote effective utilization of waste)

8. Improving the Local Environment

Dried-synthetic rubber waste incinerator (Kashima Plant)

Dried-synthetic rubber waste incinerator (Kashima Plant)

JSR values the opinions of local residents and considers high transparency of plant operations to be the key to improve the local environment. With this in mind, we have strived to improve the local environment by implementing monitoring and tours of environmental equipment at regular intervals. In FY2007 and FY2008, we installed equipment to incinerate dry synthetic rubber dry exhaust (RTO*9) at the Yokkaichi, Kashima, and Chiba plants to prevent foul odors. In FY2009, a ground flare was installed at the Yokkaichi Plant to prevent noise and flashes. As a result, there have been no environmental complaints from FY2009 to FY2016.
We will continue striving to maintain our basic policy of improving the local environment.
