Resource Circulation
For manufacturers who use resources to provide products and services, resource recycling is an important management issue, and the responsibility to form a “recycling-oriented society” is becoming more and more important.
SII uses many resources such as mineral resources, plastics, and biological resources like wood and paper as materials for products, and chemical substances and water resources in the production process. SII makes efforts to use resources effectively and reduce waste based on the 3Rs, not only from a manufacturing and sales perspective but throughout the entire lifecycle from the acquisition of resources to disposal and recycling.
We strive to thoroughly implement waste reduction by extending the service life of products and making them smaller and lighter, and recycling by using recycled materials and recycling resources.
Waste
FY 2022 Overview
SII highly regards efficient use from the upstream resource stage based on the 3R concepts. Also, SII recycles as much as possible. When SII discards waste, it finds subcontractors that can recycle the waste to minimize the amount sent to the final disposal site.
In FY 2022 as well, SII worked hard on a stable resource cycle based on the 3Rs, for example, by improving the number of items acquired from materials, downsizing products, and reusing cleaning agents.
The amount of waste generated at domestic sites was roughly the same as the preceding fiscal year. At domestic sites, roughly 80% of waste is general waste, sludge, waste plastic, and scrap metal. At overseas sites, scrap metal was reduced due to a reduction in production, and the amount of waste generated was reduced by 8%.
Amount of Waste Generated and Recycling Rate at Sites in Japan
| Total amount of waste generated at sites in Japan: 1,019 tons |
14 tons increase, or +1% from FY 2021 |
| Emissions include valuable resources. The total of emissions and breakdown may not match due to fractional amounts. |

Amount of Waste Generated and Recycling Rate at Sites outside Japan
| Total amount of waste generated at sites outside Japan: 2,496 tons |
214 tons decrease, or -8% from FY 2021 |
| Emissions include valuable resources. The total of emissions and breakdown may not match due to fractional amounts. |

Water Use
FY 2022 Overview
Recognizing that water is a precious natural capital, SII is working on the 3Rs of water resources. In addition to reducing water consumption itself, we are also working to recycle water used in the manufacturing process.
In FY 2022, we reduced water consumption by 7% at sites in Japan and by 10% at overseas sites compared to the previous year.
Changes in Water Use at Japan Sites
| Japan sites: 293K m³ | 21K m³ decrease, or -7% from FY 2021 |
| The disparity may not align with the differences in graph values due to fractional processing. | |
Changes in Water Use at Overseas Sites
| Overseas Sites: 153K m³ | 17K m³ decrease, or -10% from FY 2021 |
| The disparity may not align with the differences in graph values due to fractional processing. | |
