Industrial Waste

The Mitsui Chemicals Group aims at minimizing the landfill rate for industrial waste to 1% or less. In order to reduce the landfill volume, we are implementing waste reduction measures such as energy recovery and recycling wastes into cement materials and base course materials for road. In fiscal 2019, we achieved the goals set by Mitsui Chemicals Inc. and domestic affiliates, making a total of nine consecutive years of meeting these goals. Overseas affiliates have now achieved their goals for eleven consecutive years.

The Waste Management and Public Cleansing Law was revised partially to tighten controls over inappropriate disposal of waste. Due to this revision, business operators who discharge 50 tons or more of specially controlled industrial waste must use an electronic manifest from fiscal 2020. To fully meet the requirements of the revised Law, we have started the operation of the electronic manifest.
