Initiatives to Reduce Waste

Materiality Focus

Waste recycling rate

The Toray Group is carrying out zero emission initiatives as it works toward the realization of a sustainable, recycling-based society. Under the Fourth Medium-Term Environmental Plan, the Group worked to achieve its fiscal 2015 targets for rates of simply disposed waste,6 landfill waste7 and recycled waste,8 which have been set as indicators for measuring progress toward attaining zero emissions.

  1. 6 Simply disposed waste rate = (incineration +landfill) / total waste
  2. 7 Landfill waste rate = landfill waste / total waste
  3. 8 Recycling rate = (recycled resources + resources with monetary worth) / (total waste + resources with monetary worth)

Results in Fiscal 2015

Simply Disposed Waste Rate

Each Toray Group company worked on waste reduction and recycling. As a result, the simply disposed waste rate for the Toray Group decreased by 1.3 percentage points year-on-year to 21.1% in fiscal 2015.

Zero Emissions Initiatives at Companies and Plants

The Toray Group considers a plant to have achieved zero emissions when the amount of simply disposed waste accounts for 1% or less of the total waste it generates. The Group surpassed its fiscal 2015 target of achieving zero emissions at 30 or more plants, with 40 plants at 22 companies achieving zero emissions. Six plants newly achieved zero emissions, but three plants that achieved it the previous year did not.

Pursuing Diverse Initiatives to Reduce Environmental Impact

The Ehime Plant of Toray Industries develops and manufactures carbon fiber composites that are used in aircraft structural components, water treatment equipment, polyester, acrylic, and nylon fibers, and high-performance resins. We place the highest priority on safety, accident prevention, and environmental conservation, and pursue initiatives to reduce the environmental impact of our operations and take preventative measures.
The Toraylon section that I work in oversees the production of acrylic fibers as well as directing the operational management of wastewater treatment processes. My job is to improve wastewater treatment processes. In fiscal 2015, we successfully developed and installed a device that propagates and continuously adds the water purifying AI-1 enzyme manufactured by Group company Toyo Shokusan Inc., and the Mitagen enzyme (a type of natto enzyme), to enhance biological treatment and realize a consistent environment for wastewater treatment. We also conduct wastewater training and drills for plant employees, to further increase environmental awareness throughout the plant. Furthermore, we successfully implemented an upgrade to improve the emergency collection system in case of an irregularity, as part of our ongoing efforts to realize environmental improvements.
