Industrial Waste

With the aim of minimizing the landfill rate for industrial waste to 1% or less, The Mitsui Chemicals Group is implementing waste reduction measures and recycling to reduce the landfill volume. In fiscal 2018, we achieved the goals set by Mitsui Chemicals Inc. and domestic affiliates, making a total of eight consecutive years of meeting these goals. Overseas affiliates have now achieved their goals for nine 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 are preparing to use this electronic manifest not only for specially controlled industrial waste but for our entire industrial waste disposal operations.
