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.
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 2024 Activities
Waste volume of domestic and overseas groups
For fiscal year 2024, the total waste volume (treatment volume) across the entire domestic and international group increased due to the inclusion (boundary expansion) of Y-ATG's Vizag plant in India, which commenced full-scale operations, and a 30% increase in overall tire business production volume.
Despite efforts to improve production efficiency and quality, the total waste volume increased by 8.6% year-on-year to 59,339 tons.
In fiscal year 2022, 942 tons (1.93%) of waste was landfilled, followed by 1,959 tons (3.59%) in fiscal year 2023.
In fiscal year 2024, despite increased production, landfill disposal decreased by 1,933 tons (3.26%).

PCB Waste Storage and Management
We properly store and dispose of used PCB-containing equipment in accordance with laws and regulations.
39.1 tons of PCB-containing equipment was disposed of in FY2024.
In 2025, we will continue to properly dispose of PCB-containing equipment in use.

Hazardous Waste Disposal Flow
Introduction of Initiatives
At the Onomichi Plant, we have improved and strengthened water filtration capabilities, worked to stabilize water quality, and succeeded in significantly improving the period of possible repeated use.
Amount of waste material generated at production bases in Japan
In fiscal year 2024, waste generation amounted to 13,840 tons, representing a 1.2% increase from the previous year.
The waste generation rate per unit of sales (waste generation intensity) also decreased by 5.9% year-on-year.
The increase in waste generation is attributable to a 4.3% rise in production volume.
Conversely, the small increase in the unit intensity rate is attributable to a 7% increase in sales.

Conversely, the small increase in the unit intensity rate is attributable to a 7% increase in sales.
The processing flow for waste materials at production bases in Japan during fiscal year 2024 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 2024, a total of 74 audits were conducted within domestic group companies, while 96 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
