Michelin, Tereos aim to use crops to make rubber for tyres
PARIS Dec 9 (Reuters) - Michelin and Tereos said they would join forces to develop a rubber derived from sugar beet, grain and waste that could replace some of the natural and oil-based synthetic rubber used in tyres.
They aim to build an industrial unit by 2020, said a spokesman for Tereos, the world's fourth-largest sugar company.
Michelin, one of the world's largest tyre makers with an output of nearly 170 million tyres last year, is seeking to diversify its sources of supply as the petroleum-based synthetic rubber it uses becomes more expensive.
"The idea is to have a greener tyre - to replace the component that is not green, i.e. synthetic rubber, or even a part of the Hevea (natural) rubber by biomass derived from residues, waste etc.," the Tereos spokesman said on Monday.
The tyres would be made with an alcohol derived from sugar beet, wheat or maize, or from crop waste and residues, said Tereos, which is the largest European maker of industrial alcohol.
Tests have shown that rubber can be made from biomass, but the companies had not yet decided which commodities to use, nor what percentage of rubber content in a tyre that it should replace, the spokesman said.
The deal between grower-owned Tereos, whose sugar cane and grains unit Tereos Internacional is listed in Sao Paulo, and Michelin is part of the BioButterfly project, which seeks ways to make environmentally friendly synthetic rubber.
The tyre-making industry accounts for about 60 percent of global rubber consumption. (Reporting by Sybille de La Hamaide; editing by Jane Baird)
