Solution: Recycling is Global Issue
Reuse in Original Form & Material Recycling
“Resource & Recycling” is critical global issue now. We inspect and sort good quality used tires and supply to retread tire manufacturers as tire casings all over the world. Moreover, used tires are used effectively as fenders in harbor, play equipment in park, etc. Besides such reuse in original forms, we do decompose waste tires into rubber and steel. Rubber is crushed into rubber powder (granular or powder) and reused such as reproduced rubber materials (tire material, belt, rubber board, etc.), various rubber products for industrial use, elasticity rubber pavement material (golf course, tennis court, promenade, etc.) and permeable pavement materials.
We deal with;
- Waste Tires (from bicycles to Specialized Industrial vehicles)
