Question by tbmass: Does crumb rubber from waste tires have to be devulcanized to be used in recycling applications?
I am finding conflicting information about this topic. Does the crumb rubber that comes from waste tires have to go through a devulcanization process which breaks the cross linked polymer in order to be used for any recycling process? Or can crumb rubber as is be used? Examples being construction materials like concrete with rubber additive. Thanks 🙂
