Vipal evaluating use of rice husk in its compounds

Vipal Rubber is researching the possibility of using rice husk residue as a raw material for the rubber industry, the result of a partnership between Vipal, the University of Caxias do Sul, in Brazil, and Lodz Poland University of Technology. Goodyear released a rice husk silica tyre in China in mid-2015, before announcing in November 2020 that is would double its rice husk usage by 2021; and Pirelli announced that it was researching the use of rice husk ash in new tyre compounds back in April 2009; but Vipal is the first retreading compound maker to go public with its use of rice husks in compounding.
