Resource Recycling Efforts

Resource Recycling Efforts

The Toyo Tire Group considers our mission to contribute to the shift from a society that consumes resources to one that recycles as the social responsibility of a manufacturer that conducts business globally.
As the scale of our production activities expands, the amount of raw materials we use also increases. Therefore, we strive to secure a stable and sustainable supply of raw materials indispensable for business growth, such as natural rubber, the main raw material in the procurement stage, in terms of both quality and volume. We are also moving forward with efforts to develop new materials and to improve product design and production processes to make more efficient use of materials.
We are working to reduce waste in our business activities with a target of achieving a waste recycling rate of “100% by the end of fiscal 2020.” As for when products are used, efforts are being made to extend the service lives of products, which includes manufacturing products with outstanding durability and producing reused tires (retreaded tires) from used tires.
All of the Group’s business sites completed risk assessments stipulated by the Industrial Safety and Health Act. In addition to responding to the added chemical substances, we are also introducing reduction measures. There were no significant spills that we were liable for in fiscal 2017.

<Examples of resource recycling efforts>
  • Moving away from incinerating waste and switching to thermal recycling
  • Replaced wooden pallets with more durable plastic pallets
  • Examining alternatives for regulated substances
  • Efforts related to chemical substance risk assessments based on independent initiatives, wear dust, and used tires

TOYO TIRES Brand, also known for High Quality Recycled (Retreaded) Tires

Collecting and recycling used tires is an important issue in the tire industry for recycling resources. As one solution, we are working to spread the use of retreaded tires.
Retreaded 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*.
We produce and supply highly durable, high quality tires, and we have received high praise from users regarding retreaded products.
We contribute to the promotion of resource recycling in the transportation industry by spreading the use of high quality retreaded tires.

<Retreaded tire production flow>

There are two methods of retreading: In Remold method, new tread rubber is applied to tire casting. It is then placed in a mold and vulcanized to form tread. In Pre-cure method, previously prepared tread strip is applied to tire casing and vulcanized in a vulcanizer.
Our group has established high technology in both construction methods and produce with both.
