Goodyear to use rice harvest waste in making fuel-efficient tyre treads
Leading tyre manufacturer Goodyear will utilize ash left over from the burning of rice husks to produce electricity as an environmentally friendly source of silica for use in its tyres. After two years of testing the silica derived from rice husk ash at its Innovation Center, the company has found its impact on tire performance to be equal to traditional sources.

According to the Food and Agricultural Organization of the United Nations, every years more than 700 million tons of rice is harvested worldwide. And disposal of rice husks is a big environmental challenge. As a result, husks often are burned to generate electricity and reduce the amount of waste shipped to landfills.
“The use of rice husk ash will provide Goodyear an alternative source of silica while helping reduce the amount of rice husk waste being landfilled,” said Joseph Zekoski, Interim Chief Technical Officer. “This illustrates Goodyear’s commitment to innovation and to the environment.”
The silica is mixed with rubber in tire treads to increase the rubber’s strength and help reduce rolling resistance, which ultimately improves fuel economy. It also can have a positive impact on a tyre’s traction on wet surfaces.
“Goodyear’s innovation efforts are focused on making tires more environmentally friendly – in their materials, in their performance and in the manufacturing process. For example, we continue to explore ways to increase the fuel efficiency of tires. We strive to help consumers keep their tires operating optimally, through innovations such as Air Maintenance Technology (AMT). And we look to renewable resources, including soy bean oil, to replace petroleum-based materials in tires,” said Zekoski.
