Management of Chemical Substances

Basic Approach

Based on laws and regulations such as the Pollutant Release and Transfer Register (PRTR) Act, the ENEOS Group strives to properly manage chemical substances and reduce emissions of such substances. In addition, we are shifting to chemicals with lower impacts on health and the environment.
We are also committed to properly managing chemical substances not covered by these laws and regulations.


For information on our structure, see Environmental Management.

Major Initiatives

Compliance with Laws and Regulations

Management and Monitoring of Specified Chemical Substances under Japan’s Pollutant Release and Transfer Register Act

The Group manages and monitors the release and transfer amounts of specified chemical substances, such as benzene, toluene, and xylene, which are found in gasoline, based on Japan’s Act on Confirmation, etc. of Release Amounts of Specific Chemical Substances in the Environment and Promotion of Improvements to the Management Thereof (Pollutant Release and Transfer Register Act).
In fiscal 2022, the Group’s releases totaled 2,575 tons, an increase of 826 tons over the previous fiscal year, and transfers totaled 344 tons, a decrease of 25 tons over the previous fiscal year.

Management and Detoxification of PCB1 Waste

The Group carries out storage notification and systematic treatment of PCB waste based on Japan’s Act on Special Measures concerning Promotion of Proper Treatment of PCB Wastes (PCB Special Measures Act).
JX Nippon Tomakomai Chemical, which has been certified by the Minister of the Environment to provide low-concentration PCB waste treatment, carries out detoxification operations, thereby contributing to compliance with the Stockholm Convention on Persistent Organic Pollutants2.

For more information, see Low-Concentration PCB Waste Detoxification.

  1. 1Polychlorinated biphenyl (PCB): Due to its excellent electric insulation properties, this chemical compound was used mainly in applications such as insulating fluids for transformers and capacitors, and carbonless copiers. However, its production and import are now prohibited.
  2. 2A treaty regulating the production, use, and proper treatment of persistent organic pollutants, including PCB

Compliance with Domestic and International Regulations

Laws and regulations on the handling of chemical substances are being developed both in Japan and abroad to protect the environment, as well as safety and health. There are also cases where countries have newly implemented chemical substance registration systems or modified existing ones.
The Group takes necessary steps, such as registering substances in chemical substance registration systems in accordance with regulations in Japan and abroad, including the REACH Regulation in Europe and the Law concerning the Examination and Regulation of Manufacture, etc. of Chemical Substances in Japan.

Guidelines on Chemical Substances in Our Products and Management of Chemical Substances

ENEOS has voluntarily established standards for managing the chemical substances used in its products.
We have specified prohibited substances (such as most organochlorine compounds, mercury compounds, lead compounds, and phthalates) and substances that require monitoring (such as VOCs including toluene, xylene and the like) to better manage their use in products, and we are working to mitigate any harmful effects they may have.
In addition, we provide essential product safety information to customers and others involved with our products using methods such as safety data sheets (SDS). In the event that we obtain new information about any hazards or environmental impacts of our products, we promptly update the relevant SDS to provide the latest information to customers and others.

Businesses that Contribute to Appropriate Management of Chemical Substances

Detoxification of Waste Asbestos

The treatment of waste, including asbestos, which was used in large quantities in the past, has become a major social issue.
JX Nippon Environmental Services performs high-temperature melting and detoxification of asbestos, responding to society’s need for waste treatment. In fiscal 2022, the company treated approximately 2,800 tons of waste asbestos.

Low-Concentration PCB Waste Detoxification

JX Metals Tomakomai Chemical rotary kiln furnace

Since March 2014, when JX Metals Tomakomai Chemical received certification from the Minister of the Environment as the first low-concentration PCB waste detoxification facility in Hokkaido, the company has been working to improve its treatment capacity.
A deadline of March 31, 2027 has been prescribed by law for disposal of waste materials containing PCB. By that date, the owner must either dispose of such materials or have their disposal handled by an agent. However, there are only 25 incineration facilities in Japan, including JX Nippon Tomakomai Chemical, capable of detoxifying not only low-concentration PCB waste materials but also the transformers, drums, and other housings that contain them. Moreover, there are only 12 treatment facilities that perform decontamination by means of cleaning processes. The number and capacity of these facilities is still inadequate to meet the demand for low-concentration PCB waste disposal.
Moving forward, we will maintain stable operations for the treatment of industrial waste as part of our efforts to contribute to the environmental conservation of local communities.
