Management of Chemical Substances / Resource Conservation Sustainability

Management of Chemical Substances

Chemical substances used at each site are accurately recorded and put under appropriate control in accordance with their properties and relevant laws. In particular, at sites that handle designated chemical substances under the PRTR Law*, we have established management standards and work standards, and implement operational management that takes into account the health of our employees. Since chemical substances are used as raw materials, emissions tend to increase along with the expansion of business. However, we are working to reduce environmental burden by reviewing formulations and by collecting and reusing chemical substances.

Substances Listed under the PRTR Law


PRTR Law-designated Substances

* PRTR Law: Law requiring companies to accurately record the amount of specified chemicals discharged into the environment, and report these amounts to the government. For Kurabo, dichloromethane, which is used as a foaming agent of urethane, accounts for the largest portion of total PRTR substances discharged.

Resource Conservation

To reduce raw material waste generated from plants, we practice resource conservation and develop applications where the waste can be used.

  • ・The Tokushima Plant, which performs dyeing and processing of synthetic cotton fabric, uses a large quantity of caustic soda. The majority of the caustic soda is recovered from discharged wash water and is condensed for reuse.
  • ・At the Neyagawa Plant and the Gunma Plant, all of the molding waste generated in the production process of extrusion-molded products for housing materials is reused for molding materials.
  • ・The off-cuts of flexible urethane foam manufactured at the Susono Plant and the Kamogata Plant are crushed, molded, and reused as rebonding foam.
  • ・In the Mie Plant, remnants from plastic film manufacture are recycled and reused as material when and where possible.
  • ・The Textile Business Division collects off-cuts from the sewing process and reuses them as raw material, such as in textile products, at the Anjo Mill. These textile products are sold under the "LOOPLUS" brand.
