Reduction of Waste Volume in Business Activities

Toshiba Group is working to reduce waste generation by minimizing the volume of waste generated per unit activity, which indicates business process efficiency improvement, as well as by reducing the total volume of waste to a level that does not exceed the Earth's environmental capacity.

In FY2022, the volume of waste (excluding that of objects with value) totaled 30,000 tons. The total volume of waste generated per unit production was 101% compared to that of FY2021 level, which means that the target was not achieved.

We are first focusing on not generating waste and aiming to improve the recycling rate. At each stage of design, development, production, and distribution, we give thorough consideration to reducing, recycling, and facilitating waste disposal. We monitor the composition of waste and promote the reduction or elimination of hazardous substance content, as well as thorough sorting and storage.

In addition, the total volume of hazardous waste*1 is 3,100 tons in FY2022, the recycling rate*2 is 83%, and the volume discharged and moved*3 is 744,052 kg.

  • The total volume of hazardous waste indicates the quantity of specially controlled industrial waste specified by the Waste Management and Public Cleansing Act of Japan (the “Waste Management Act”).
  • The volume recycled refers to the quantity reused or recycled of the specially controlled industrial waste specified by the Waste Management Act.
  • The figure is determined based on the volume discharged and moved of the substances that are managed by Toshiba Corporation among all the substances defined in the U.S. Comprehensive Environmental Response, Compensation, and Liability Act (CERCA).

■ Breakdown of the waste volume (FY2022)

  • Basic-unit uses values such as production output, the number of products manufactured, the number of persons and total floor area, etc, that are related to the total volume of waste generated associated with manufacturing.
  • The rate of improvement per unit activity of output with FY2020 as 100%
  • The target values are for the waste volume only.

Promoting Recycling

In FY2022, Toshiba Group recycled 85,000 tons of resources, and 90% of the total volume of waste generated was reused effectively as various resources. The recycled resources consisted mainly of scrap metal, waste paper, and wood chips, and 89% of them were used effectively for material recycling (recycled into materials for products), and the remaining 10% for thermal recycling (heat recovery). In the future, Toshiba Group will continue to increase the total volume of resources recycled and at the same time will strive to raise the quality of recycling chiefly by increasing the percentage of resources recycled into materials.
