Maris Corp. – an Italian innovator in the field of end-of-life tire rubber devulcanization – reports that the use of devulcanized rubber produced with its patented process and mixed with virgin rubber allows reducing the environmental impact of CO2 and the consumption of fossil resources.

Recently, Maris team – Bruno Muscato and Marco Girotto – collaborating with colleagues from the University of Turin published an article on this matter in Science Direct's Journal of Cleaner Production. The article is headlined as “Environmental assessment of rubber recycling through an innovative thermo-mechanical devulcanization process using a co-rotating twin-screw extruder.”
