Resource Saving and Waste Reduction

We are systematically working to reduce the amount of exhaustible raw materials used, quickly and properly dispose of PCB waste, and reduce the amount of industrial waste sent to landfills.

  1. Promoting Resource Saving
    We are striving to enhance the economic benefits gained from resource saving activities, such as improving the throughput yield of exhaustible raw materials and product yield.

  2. Thoroughly Managing Waste and Reducing Landfill Waste
    We have achieved a major reduction in industrial landfill waste by reducing the amount of industrial waste generated and promoting recycling. In addition, as a specified resource industry identified by the Act on Promotion of Effective Use of Resources, we are also working to systematically limit the generation of industrial byproducts (sludge).
  3. Moving up the Schedule for Comprehensive Treatment of Waste with Minute Amounts of PCBs before Legal Disposal Deadline
    We winnowed the external operators jointly contracted to dispose of waste by main Group companies down to just one. Regarding the waste with minute amounts of PCBs (transformers, condensers, etc.) being stored or used by each company, we formulated a plan to comprehensively treat the waste over multiple years and are promoting proper management. We plan to dispose of all such waste by March 2025. (We expect to dispose of a total of around 500 pieces of equipment and around 1,800 tons of waste.)
