Reducing Environmental Impacts

Waste reduction

The Toyo Tires Group is striving to achieve the goal of realizing a waste recycling rate of 100% by the end of fiscal 2020.

In fiscal 2011, due to suspended operations of some industrial waste disposal operators affected by the Great East Japan Earthquake, some of the generated waste could not be recycled, resulting in an increase in our total landfill volume. However, since then, the landfill waste volume has continued to decrease. In fiscal 2015, the total amount of waste generated was 18,881 tons, down 0.3% from the previous year, and the amount of landfill waste was 3 tons, down 99% from the previous year. Both figures were below pre-earthquake levels.

Our recycling rate also steadily improved to 97.5% in fiscal 2015.

Moreover, we conducted on-site inspections of operators commissioned with industrial waste collection, transportation and disposal and confirmed the absence of problems with regard to environmental compliance.

In fiscal 2016 and onward, we will continue our efforts to further improve waste recycling rates at all our business sites in Japan, while ensuring thorough compliance with environment-related laws and regulations.

Recycling of used tires

Under the leadership of the Japan Automobile Tyre Manufactures Association (JATMA), the tire industry as a whole is striving to promote the recycling of used tires. In 1990, ahead of other companies in the industry, the Toyo Tires Group introduced into the Sendai Plant a cogeneration system that uses scrap tires as a source of fuel. Through establishing such thermal recycling, we have been vigorously promoting the reduction of fossil fuel use and effective use of resources.

Spreading use of retreated (reused) tires

Retreading tires involves replacing the tread (the part of a tire that comes into contact with the road surface) on worn tires to make them serviceable again. Since retreading reuses all the remaining part of the tire, it naturally saves resources and even emits less CO2 than in manufacturing new tires. Applied and managed in combination with fuel-efficient tires, retreading can bring about even greater energy-saving results. For these environmentally positive traits, in April 2002, retreaded tires were designated as a specified procured item under the Law Concerning the Promotion of Procurement of Eco-Friendly Goods and Services by the State and Other Entities (“Green Procurement Law”) of Japan.

By further spreading the use of retreaded tires, the Toyo Tires Group intends to continue contributing to reducing environmental impact due to transportation.

Retreading processes



Remolding: Raw rubber is applied to the tire casing; it is then placed in a mold so that rubber is vulcanized and the tread is formed.
Pre-curing: Prepared tread strip is applied to the tire casing; rubber is vulcanized in a dedicated case.
