Curtailing Emissions of Chemical Substances in Exhaust
Management of Compliance with Regulatory Values
The Oji Group owns a number of thermal-fired electric power
generating plants. The electric power and thermal energy
obtained through direct combustion of fossil fuels, waste fuels,
and renewable fuels is used internally and provided to local
The Group has set voluntary management standards that
are stricter than the regulatory values with regard to the
atmospheric release of the chemical substances produced
through direct combustion. In cases where voluntary standards
are exceeded, suspension of operations and other measures
are taken for the prevention of pollution.
Exhaust Purification Targets and Results
The FY2018 targets for exhaust purification were as follows.
・Reduce SOx(※1) emissions intensity by 1% compared to the previous year
・Reduce VOC(※2) emissions intensity to below the FY2010 level (plants that handle volatile organic compounds)
Both targets were achieved.
Status of Reductions in Chemical Substances in Exhaust
Emissions of chemical substances and dust are reduced
through technological advances in combustion boiler structure,
desulfurization facilities, dust collection facilities, and other
areas and use of operational technologies.
The Group makes continuous operational improvements
and performs rigorous management of equipment for reducing
substances of environmental concern and will continue to
implement measures for the prevention of pollution and work
towards achieving the FY2019 targets.

(※2)VOC：Volatile organic compounds
Volatile organic compounds (VOC) are said to be a cause of photochemical oxidants. VOC is the collective name for organic compounds that are volatile and change into a gaseous state in the atmosphere. A wide variety of substances exist as VOC, including toluene, xylene, and ethyl acetate. Until 2010, the Oji Group had been reducing VOC emissions by using combustion facilities and absorption facilities. Since then, our target for each year has been to maintain the 2010 level of VOC emission intensity per sales (0.56 kg of emissions/million yen). As a result, we have maintained the 2010 level of VOC emission intensity since 2013 as well.
