The 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 2015, the Toray Group recorded 3,192 tons of SOx emissions (down 13% year-on-year) and 2,318 tons of NOx emissions (down 13% year-on-year). Due to increased production volumes, the Group recorded 331 tons of dust emissions (up 13% year-on-year). On a non-consolidated basis, Toray recorded 298 tons of SOx emissions (down 22% year-on-year) and 1,456 tons of NOx emissions (down 12% year-on-year) due to the factors such as introduction of a cogeneration system at the Mishima Plant. However Toray recorded 108 tons of dust emissions (up 6% year-on-year), due to increased production volumes at the Ehime Plant and other factors.
Group company P.T. Indonesia Synthetic Textile Mills also reduced its SOx emissions by switching to higher quality fuels.

In fiscal 2015, the Group expanded its wastewater treatment facilities at the following plants: the Ehime and Tokai Plants of Toray, the Fukui Plant of Dow Corning Toray Co., Ltd., and the No.2 Plant of Luckytex (Thailand) Public Company Limited. These upgrades further stabilized wastewater treatment to realize benefits.
The Group brings together wastewater managers every year to share and discuss strategies for enhancing wastewater management at production sites. The fiscal 2015 meeting was attended by 27 persons from nine Toray plants and five persons from five Group companies in Japan.
