All Kyocera Group corporate activities are based on our corporate motto, "Respect the Divine and Love People," and our three pillars for "LIVING TOGETHER": coexistence with society, coexistence with the global community, and coexistence with nature.
We aim to establish a recycling system that reduces the consumption of natural resources with the goal of protecting the global environment and realizing a sustainable society.
Contribution to the Circular Economy
The Circular Economy Concept
Laws and regulations have been established and standardized with increasing frequency throughout the world. The EU has pioneered the implementation of circular economy action plans, and has actively set goals to reduce the total amount of waste incineration and landfill. In line with these movements, the Kyocera Group established a new division to build a system for the reuse of a wide variety of waste produced at the factories in recycled materials with the goal of achieving zero waste discharge.
Approaches to the Circular Economy
Environmental-load reduction for packaging materials
The Kyocera Group promotes the reduction of material use and utilization of recycled resources through the design and development of packaging materials.
Designs for resource-savings
The Kyocera Group contributes to the reduction of environmental load while maintaining functionality through decreased material use by adopting new-style folding boxes.
Recycling of Disposed PET Film
The Kyocera Group strives to reuse PET film waste generated at its production sites as an ingredient for PET product trays. The Group set the goal of using recycled PET film at a level of 50% or more for trays to reduce the use of new ingredients as much as possible.
Circular system for multifunction peripherals (MFPs) and printers
Kyocera Document Solutions Inc. has established a circular business cycle encompassing product design, production, collection, and recycling.
Environmentally conscious designs
The Kyocera Group has implemented long-life designs, 3R (reduce, reuse, recycle) designs, and low energy-consumption designs, and has strived to reduce environmental load since the initial stage of product development in accordance with the Environmentally Conscious Design Standards.
Post-consumer recycled (PCR*) plastic utilization
The Kyocera Group has implemented PCR for products and toner containers. The Group set the goal of 1% or more PCR utilization in 2023, 5% or more PCR utilization and the use of recycled materials at 50% of all MFPs in 2024.
PCR：Plastic materials that have been collected from consumers after use and recycled into new plastic products.
From Collection to Reuse
We collect used MFPs and printers and promote their reuse at both the material and product levels in selected regions. By enhancing designs that facilitate easier refurbishment, we aim to expand reuse across our product portfolio.
Recycling of used mobile phones
The Kyocera Group makes effective use of the valuable resources contained in mobile phones as a way of reducing environmental impact.
Mobile Recycling Network (MRN)
The Kyocera Group promotes collection and recycling activities in cooperation with other companies through the Information and Communication Network Industry Association of Japan (CIAJ). Mobile phones are collected nationwide by collection centers for recycling to prevent environmental destruction by mining.
Recycling of machine tools
The Kyocera Group contributes to zero emissions at plants through its recycling program for used chips and chip cases from machine tools.
Chip case recycling program
The Group carries out collection and recycling activities for used carbide materials and chip cases aiming to achieve both improvement of productivity and sustainability, and contribute to the reduction of environmental load.
Collecting rare earth elements from fuel cells
The Kyocera Group continues developing fuel cell recycling technology to promote resource circulation.
Extraction and recycling of rare earth minerals
The Group promotes the recycling of rare earth minerals extracted from used fuel cell stacks. The Group contributes to the effective use of resources through the development of recycling technology.
Approaches to Waste Reduction
Resource recovery rate
Until FY2024, Kyocera defined thermally recycled wastes as recyclable wastes. From FY2025, in order to promote the circulation of plastics and other resources, Kyocera defines thermal recycled wastes as non-recyclable wastes and strives for reduction. In FY2025, the Kyocera Group advanced waste reduction by setting individual targets at five production sites that generate more non-recyclable wastes than other locations do. However, from FY2026, the scope will be expanded to include Kyocera's domestic production sites, Kyocera Document Solutions' production sites, KYOCERA Thailand, and KYOCERA Vietnam. At the same time, the company will shift to setting absolute volume targets. The Group continues striving to realize a sustainable society.

According to the previous definition (including thermal recycling as a category of recyclable waste), recycling ratio by the Kyocera Group (Japan production sites) in FY2025 was 99.5%.
The definition of the recycling rate (%) is "1 - final disposal amount/discharge amount" x 100.
Recycling rates have not been provided for the four main electric and electronic goods industry bodies for FY2025 and have been omitted.
Waste Discharge
The Kyocera Group manages the amount of waste discharged and disposed of in landfills from the viewpoint of resource recycling. The Kyocera Group evaluates the waste discharge rate and waste treatment cost rate, and indicates the locations with high waste risk.
As a result of the FY2026 waste risk assessment, there were 11 sites with high waste risk, and the total amount of waste discharged was 28,923 tons, accounting for 67% of the total amount of waste discharged in FY2025.

Range of Waste to be Recycled
FY2021～2023：[Japan] Industrial Waste+ Specially Controlled Industrial Waste [Overseas] hazardous waste
FY2024～：[Japan]Industrial Waste+ Specially Controlled Industrial Waste + General Waste [Overseas]Hazardous waste+ Non- hazardous waste
The basic unit is calculated based on the Range of Waste to be Recycled. (Until FY2023, it was calculated from the amount of waste generated; from FY2024 onward, it is calculated from the total amount of waste generated, including general waste and non-hazardous waste.)
Data in FY2023,2024 has been updated to improve the accuracy of data aggregation at some locations.
Cases of Waste Reduction
Reduction of industrial waste by volume reduction of grinding waste liquid
The Kagoshima Kokubu Plant implemented forced air evaporators to evaporate water content from polishing waste liquid, which leads to the reduction of waste liquids and the overall reduction of industrial waste. The plant uses waste heat to increase the temperature of the forced air evaporators.
Total Waste Reduction: 458 t/year*
Total amount of reduction by 2 units is shown. (1 unit was implemented in FY2023).
Reduction of Industrial Waste by Implementation of Fenton Pre-treatment Equipment
The Kyoto Ayabe Plant implemented Fenton pre-treatment equipment to process wastewater containing high-concentrations of organic substances. Before implementation, the plant was unable to process concentrated wastewater using previous water treatment methods, forcing disposal as industrial waste. Implementation of the Fenton pre-treatment equipment allows the plant to process concentrated wastewater using currently available methods, which reduces the discharge of industrial waste.
Total Waste Reduction: 676 t/year
Reduction of industrial waste by volume reduction of grinding waste liquid
KYOCERA OPTEC (DONGGUAN) CO., LTD. reduced its industrial waste by installing centrifuges for its lens manufacturing process, which allow polishing solution to be reused by separating out impurities.
Total Waste Reduction: 120 t/year
