Our position and Targets
Why is “Effluents and Waste” a critical issue to be addressed?
Explanation of the reason and background
We believe that minimizing the impact of our business activities in Japan and overseas on the environment will lead to sustainable operations. Accordingly, we believe that it is important for effluents and waste to be minimized as much as possible in a form with a low environmental impact.
In particular, we believe it is crucial to properly handle hazardous waste without resorting to transportation or importation to foreign countries.

Vision (attainment goal) / target
We will work to achieve a reduction of 1% in waste materials per unit of waste※1, and aim for the attainment and maintenance of 100% recycling※2, We will then aim to achieve total zero-emissions※3.
- 1 We monitor the generation and disposal volumes of industrial waste in accordance with each country's regulations and report the disposal volumes.
Domestically, we monitor industrial waste, business-related general waste, and valuable materials, and report the disposal volumes of industrial waste and general waste. - 2 100% recycling: Achieve zero final disposal (= direct landfilled amount + incineration disposal amount resulting in ineffective use)
- 3 Total zero-emissions: Make the direct landfilled amount zero.
Measures for vision achievement
- Even in the case of business locations that are legally entitled to have waste disposed of in landfill sites, we will look for and select industrial waste disposal contractors that do not conduct landfilling, and contract with them to undertake recycling processing.
- The processing of PCB-containing devices will be conducted within the deadline specified by law.
Review of FY 2025 Activities
Waste volume of domestic and overseas groups
For fiscal year 2025, the total waste volume (treatment volume) across the entire domestic and international group increased due to the inclusion (boundary expansion) of Nippon Giant Tire, and a 7.1% increase in overall tire business production volume.
Despite efforts to improve production efficiency and quality, the total waste volume increased by 1.5% year-on-year to 60,218 tons.
In fiscal year 2023, 1,959 tons (3.59%) of waste was landfilled, followed by 1,933 tons (3.26%) in fiscal year 2024.
In fiscal year 2025, despite increased production, landfill disposal decreased by 1,796 tons (2.98%).

PCB Waste Storage and Management
We properly store and dispose of used PCB-containing equipment in accordance with laws and regulations.
5.5 tons of PCB-containing equipment was disposed of in FY2025.
In 2026, we will continue to systematically ensure the proper disposal of equipment containing PCBs currently in use, aiming for completion ahead of the statutory deadline.

Hazardous Waste Disposal Flow
Introduction of Initiatives
Waste Disposal Management at Domestic Production Sites
In FY2025, our total waste disposal volume decreased by 0.9% year-on-year to 13,721 tons, and waste disposal intensity per unit of revenue also improved with a 10.4% year-on-year reduction (while tire production volume grew by 7.7%).
This lower intensity is partly attributable to strong top-line revenue growth (up 11% year-on-year).
This lower intensity is partly attributable to strong top-line revenue growth (up 11% year-on-year).
The processing flow for waste materials at production bases in Japan during fiscal year 2025 was as follows.
1) Excluding general industrial waste
2) Consumer paper manufacturing waste, tree planting material, various consumer waste
2) Consumer paper manufacturing waste, tree planting material, various consumer waste
In fiscal year 2025, a total of 86 audits were conducted within domestic group companies, while 103 audits were carried out at overseas factories, confirming the proper handling of waste in all locations.
Participation in the “Fry to Fly Project”
Yokohama Rubber joined the “Fry to Fly Project” in August 2024, a project promoting decarbonization through domestic resource circulation.
The company provides waste cooking oil collected from cafeterias at all domestic factories and some employee dormitories to this project.
The collected waste cooking oil is manufactured into Sustainable Aviation Fuel (SAF).
In May 2025, SAF mass-produced through this project entered practical use.
The Japanese government has set a target of making 10% of aircraft fuel SAF by fiscal year 2030, and Yokohama Rubber is contributing to achieving this goal.

Future challenges
- Selection of overseas production bases of industrial waste disposal contractors that don’t conduct landfilling
- Implementation of the disposal plan for equipment containing low-concentration PCBs within the specified timeframe
- Consider increasing the effective recycling value by increasing the ratio of valuables from industrial waste
