THE NEW VALUE FRONTIER

Recycling Activities

Kyocera contributes to the goal of sustainable resource recycling by purchasing materials and supplies that have lower environmental impact, reducing new resource consumption, and minimizing waste.
The Kyocera Group manages the amount of waste discharged and disposed of in landfills from the viewpoint of resource recycling. We evaluate the amount of waste discharged, the unit cost of waste treatment, and the risks of treatment contractors at our production sites.
As a result of the FY2022 waste risk assessment, there were 6 sites with high waste risk, and the total amount of waste discharged was 14,453 tons, accounting for 41% of the total amount of waste discharged in FY2022.

Targets for FY2022
  • Implement measures to reduce waste emissions by 880 tons.
    (This target is applied to production sites with high waste risk based on an waste risk assessment.)
  • Continued 0 emissions (waste recycling rate of 99.5% or more) at all production sites in Japan.
Achievements in FY2022
  • Implement measures to reduce waste emissions by 1,566 tons.
  • Achieved 0 emissions (99.6% waste recycling rate) at all production sites in Japan.
Targets for FY2023
  • Implement measures to reduce waste emissions by 1,600 tons.
    (This target is applied to production sites with high waste risk based on an waste risk assessment.)
  • Continued 0 emissions (waste recycling rate of 99.5% or more) at all production sites in Japan.

Waste Discharge

Waste Discharge Graph

Data in FY2021 has been updated to improve the accuracy of data aggregation at some locations.

Resource recovery rate

The resource recovery rate of the Kyocera Group (in Japan) in FY2022 was 99.6%.

Resource recovery rate​

The definition of the recycling rate (%) is "1 - final disposal amount/discharge amount" x 100.

Recycling rates for the four electrical and electronics industry groups for FY2022 data have not been published and not shown in the graph.

Product Recycling Initiatives

Printer and toner cartridge recycling program

Kyocera Document Solutions is working to reduce the environmental impact of their multifunctional devices and printers by designing design products and systems based on the "Ecosys Concept." In addition, we have established a system to collect and recycle products after they are no longer needed and are actively working to recycle parts and materials.

Case Studies in Japan

Case Study in Europe, the United States, and Australia

Mobile Phone Recycling Program

Kyocera is promoting recycling to reduce the environmental impact of mobile phones. Mobile phones contain precious resources such as rare metals, gold, and silver, and by promoting recycling, they help prevent environmental destruction through mining and make effective use of resources.

Case Study in Japan

In Japan, Kyocera participates in the Mobile Recycling Network (MRN) and carries out collection and recycling activities in cooperation with other companies. Through these efforts, mobile phones manufactured by Kyocera and other companies are collected at a joint collection center to promote recycling.

Case Study in the United States

Machine Tooling Chips and Chip Case Recycling Program

Kyocera contributes to emission reduction and productivity improvement in factories with a CSR initiative to collect and recycle used carbide materials, chips, and chip cases.
