Initiatives to Prevent Air and Water Pollution

Environment

Toray Group implements ongoing initiatives at production sites to reduce sulfur oxide (SOx) emissions by installing desulfurization equipment and switching to cleaner fuels, and reduce chemical oxygen demand (COD) by expanding wastewater treatment facilities.

Air Quality Management

In fiscal 2018, Toray Group recorded 2,552 tons of SOx emissions (up 3% year-on-year), 2,047 tons of NOx emissions (down 2% year-on-year), and 271 tons of dust emissions (up 20% year-on-year). The increases in SOx and dust emissions were due to increased use of coal at group companies outside Japan.

Water Quality Management

In fiscal 2018, Toray Group recorded 824 tons of BOD emissions (up 6% year-on-year) and 1,957 tons of COD emissions (down 7% year-on-year).
BOD emissions were up due to a change in the method of operating wastewater treatment facilities at Toray Industries Ehime Plant. A reason for the improvement in COD emissions was an upgrade to the method of operating wastewater treatment facilities at Luckytex (Thailand) Public Company Limited, a group company outside Japan.

The Group brings together wastewater managers every year to share and discuss strategies for enhancing wastewater management at production sites. The fiscal 2018 meeting was attended by 21 persons from nine of Toray Industries’ plants and five persons from one group company in Japan.
