– Rice Husk Ash becomes Tyre-Grade Silica
BANGKOK, 24 September 2014 –—- Goodyear announced it will utilise ash left over from the burning of rice husks to produce electricity as an environmentally friendly source of silica for use in its tyres. Rice husk waste once headed for landfills is now helping The Goodyear Tire & Rubber Company produce fuel-efficient tyres.
The company has tested silica derived from rice husk ash over the past two years at its Innovation Centre here and found its impact on tyre performance to be equal to traditional sources. Goodyear is negotiating with potential suppliers to purchase rice husk ash silica for use in its tyres.
“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.”
Each year, more than 700 million tons of rice is harvested worldwide, according to the Food and Agricultural Organisation of the United Nations, and disposing of the rice husks is an environmental challenge. As a result, husks often are burned to generate electricity and reduce the amount of waste shipped to landfills.
Silica is mixed with rubber in tyre treads to increase the rubber’s strength and help reduce rolling resistance, which 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 tyres more environmentally friendly – in their materials, in their performance and in the manufacturing process,” said Zekoski. “For example, we continue to explore ways to increase the fuel efficiency of tyres. We strive to help consumers keep their tyres 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 tyres.”
About Goodyear Thailand
Goodyear Thailand was established in 1968 and began tyre manufacturing in 1969. In 1994, Goodyear Thailand became a public-limited company. It now provides original equipment (OE) and replacement tyres for passenger, 4X4/SUV, light truck, commercial truck and aviation customers both for domestic and export markets. Goodyear Thailand also has the only Goodyear facility in Asia Pacific and one of only three plants globally that manufactures new aviation tyres.
