Research output: Patent

Abstract

The invention relates to the recycling of used rubber products, more specifically to the recycling of Ground Tire Rubber (GTR) from cars and trucks. Provided is a method for reclaiming rubber, comprising the steps of (i) providing a starting material comprising a vulcanized rubber polymer; (ii) subjecting the starting material to mechanical stress and at a temperature of at least 200°C to achieve at least a partial destruction of the cross¬ links and the backbone structure of the rubber polymer into fragments; and (iii) reconstituting at least part of the fragments in the presence of a branching/grafting agent to obtain a renewed rubber composition.
