Protection of the Atmospheric Environment

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) implemented at the Kashima Plant (Kashima Joint Power Generator) resulted in a reduction in both SOx and NOx emissions, an achievement that was maintained in FY2015. JSR will continue to adopt the best emissions reduction technologies and will continue to make improvements.

Regarding PRTR

PRTR*1 Activities

Every year, 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 (PRTR Act*2), JSR aggregates the amount of designated chemical substances released into the environment (atmosphere, water and soil) or transferred by manufacturing or used in the previous year, and notifies the government of Japan of the results. Primarily for substances that are released in significant amounts and have a great impact on the environment, we have implemented a range of measures in a planned manner, including enhancing airtightness of their release source, rendering them harmless by incineration and improving their manufacturing processes. In FY2015, as a result of taking such measures, we reduced emissions of the substances designated by the PRTR Act (262 tons) by 90% from the FY1996 level.

Initiatives for Reducing VOC Emissions into the Atmosphere

Having set a high voluntary goal of reducing emissions of volatile organic compounds (VOCs) by 75% from FY2001 levels, JSR made a 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 VOC emissions in FY2015 were 995 tons (77% reduction as compared to FY2001) and we therefore reached our independent target. As we ramp up our production volume, we will maintain the level of the current voluntary goal (75% reduction from FY2001) without a large-scale investment by ensuring proper operation of dried-synthetic rubber waste incinerators and finely tuned maintenance and management.

Reference: VOC 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 by FY2011 from the FY2001 level with the best mix of laws and regulations, along with operators’ voluntary activities.

(2) Japan Chemical Industry Association: To achieve a 51% reduction in the amount of VOCs released into the atmosphere by FY2011 from the FY2001 level

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 FY2015.

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.
The Air Pollution Control Act and the Ordinance on Prevention of Hazards due to Asbestos were amended on June 1, 2014 to prevent asbestos from spreading in the atmosphere, and accordingly, regulations concerning building demolition work were tightened. In accordance with these amended laws, we will continue to act properly to prevent workers engaged in building demolition from acquiring health problems caused by asbestos exposure.
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.

Case Description
Yokkaichi Plant Plant Site Perimeter Odor Control Measures Since the wastewater sludge dewatering equipment building is located on the perimeter of the plant grounds, we anticipate that the sludge odor will exceed the standards set by the Odor Index, which will be introduced in 2015. Thus, we have selected a deodorizer and optimized conditions such as the concentration and amount of use, the location of use, the timing of use, and others, and we have devised an automatic dispensing method. This has led to an improvement in the Odor Index from 21 to 10 or below, which indicates that we have cleared the required level (18 or below). The odor reduction has also greatly improved the workplace environment.
Yokkaichi Plant Promoting the Reduction of Generated Waste by Improving Waste Sorting Methods We planned to reduce CO2 emissions by introducing sludge drying equipment and ceasing the use of 1 incinerator, but as we were unable to process waste oil and general waste, these were processed off-site.
Therefore, (1) We improved our sorting methods in order to prevent contamination of waste oil by water and impurities, and (2) improved our sorting methods in order to prevent contamination of paper by waste plastic and miscellaneous trash and we improved our waste paper selection process. These changes have allowed us to effectively sell these items. This resulted in our achieving reductions in environmental impact and reductions in off-site processing fee (from 30 million yen/year to 1.6 million yen/year).
Yokkaichi Plant CO2 Emission Reductions due to the Introduction of a Gas Turbine Intake Cooling System Because air density is lower during the hot summer months, the electricity output of gas turbines decreases. The amount of electricity output loss is compensated for through the use of coal boilers and steam turbines, but the use of coal leads to an increase in CO2 emissions. The installation of cooling systems on gas turbine intake vents has improved the summer output of the gas turbines and allowed us to achieve a reduction in CO2 equivalent of 1,000 tons/year.
Chiba Plant Odor Countermeasures when Receiving Resin Raw Materials Some of the resin raw materials used at the Chiba Plant have an unpleasant odor, which may leave us vulnerable to environmental-related complaints. Up to know we have controlled the amount discharged into the atmosphere and used countermeasures such as dilution diffusion of odors, but these measures have not been effective. Wrapping containers and pipes and the use of new carbon deodorizing filters has allowed us to trap odors. These preventative measures have led to decrease in the odor level to 1/10 of the previous level.

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 improving 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 2008, we installed equipment to incinerate dry synthetic rubber dry exhaust (RTO*10) 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, and as a result there were no environmental complaints from FY2009 to FY2015. We will continue to strive to maintain our basic policy of improving the local environment.
