- These include recycled steel (for the tire's belt), recycled rubber chemicals, carbon black from both recycled sources and end-of-life tire pyrolysis oil, and synthetic rubber made from sustainable materials like recycled plastic bottles.
- Bridgestone says that 38 percent of the tire's content is biological in origin—there's some para and guayule rubber, but also plant-based oils and resins, biologically derived silica from rice husk ash, and biologically derived carbon black.Another 37 percent of the tire's content is from recycled materials.
- The company will conduct tests with automakers to prove the concept.The world produces about 2 billion tires each year, and while synthetic rubbers are used in modest amounts, most road tires use a lot of natural rubber from the para rubber tree (Hevea brasiliensis).
- Now, Bridgestone is ready to try the rubber in a more practical application and has produced a demonstration run of road-going tires using guayule rubber and a high percentage of recycled materials.
- "As we progress in our transformation to a sustainable solutions company, we are making incredible progress in the use of recycled and renewable materials to bring sustainable tire technology from the drawing board to the driveway," said Paolo Ferrari, president and CEO of Bridgestone Americas.
