Chemicals Management

Management of Substances Subject to the PRTR System

Management of Substances Subject to PRTR System Notification

The Unitika Group is making efforts to monitor and reduce the volume of chemical substances that are emitted into the atmosphere, as regulated by the Pollutant Release and Transfer Register (PRTR) system as chemical substances that are potentially hazardous to human health and the ecosystem. In FY 2020 we completed the disposal of defective products and other waste caused by a fire at the Uji Plant. Subsequently, the amounts emitted and transferred both decreased compared to FY 2019 levels.

Promotion of the Chemicals Management at Domestic and Overseas Locations

The Unitika Group promotes initiatives that correspond to the Act on the Regulation of Manufacture and Evaluation of Chemical Substances, the European regulations for the Registration, Evaluation, Authorization and Restriction of Chemicals (REACH), the Globally Harmonized System of Classification and Labeling of Chemicals (GHS) and other chemical management systems in Asian countries. With meetings intended for information-sharing and compliance with the law, we are also striving to disseminate information within the group and to share information between relevant personnel.
