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 industrial waste discharged and disposed of in landfills from the viewpoint of resource recycling. We evaluate the amount of industrial waste discharged, the unit cost of industrial waste treatment, and the risks of treatment contractors at our production sites.
As a result of the FY 2021 industrial waste risk assessment, there were 12 sites with high industrial waste risk, and the total amount of industrial waste discharged was 19,572 tons, accounting for 74% of the total amount of industrial waste discharged in FY 2021.

Targets for FY2021
  • Implement measures to reduce industrial waste emissions by 2,100 tons.
    (This target is applied to production sites with high industrial waste risk based on an industrial waste risk assessment.)
  • Continued 0 emissions (waste recycling rate of 99.5% or more) at all production sites in Japan.
Achievements in Fiscal Year 2020
  • Implement measures to reduce industrial waste emissions by 1,575 tons.
  • Achieved 0 emissions (99.8% waste recycling rate) at all production sites in Japan.
Targets for FY2021
  • Implement measures to reduce industrial waste emissions by 630 tons.
    (This target is applied to production sites with high industrial waste risk based on an industrial waste risk assessment.)
  • Continued 0 emissions (waste recycling rate of 99.5% or more) at all production sites in Japan.

Industrial Waste Discharge

Industrial Waste Discharge Graph

As a result of reviewing the data of FY2020, the figures have been revised.

Resource recovery rate

The resource recovery rate of the Kyocera Group (in Japan) in FY 2020 was 99.9%.

Resource recovery rate​

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

The recycling rate for the electrical and electronics industry in FY 2020 was not disclosed.

Waste Reduction Measures

Industrial Waste Reduction by Internal Treatment

The Niigata Shibata Plant installed equipment to retrieve copper by adding caustic soda to waste acid generated from the plating equipment and then applying heat treatment. After the copper has been retrieved, the waste liquid can be processed by the existing wastewater treatment equipment, making it possible to reduce industrial waste discharge.

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.
