Reduction of Waste
- Amount of Disposal and Rate of Recycle
(SUMCO Group [Japan])
In Japan, the SUMCO Group is working to reduce the amount of waste generated as part of environmental conservation efforts. In particular, the SUMCO Group is focusing on efforts such as suppressing generation volume of waste oil, which has a large volume of emissions among waste products, by conversion into valuable resources, as well as promoting the recycling and conversion into valuable resources of sludge, waste acid, waste alkali, waste plastics, and so forth.
Waste Reduction through the Adoption of Reusable Containers
We are replacing the containers used to ship 300-mm diameter silicon wafers with reusable alternatives as one of the initiatives to reduce post-shipment waste.
The percentage of reusable containers used for shipment in 2023 was 81.2%.
Before introducing reusable containers, we conduct tests to ensure that the quality of the products is not affected.
Efforts to promote Resource Circulation of Plastic
In promoting waste reduction and recycling, SUMCO Group (Japan) established recycling goal for industrial waste of products using plastic, and is working to achieve it.
