The objective of this study is to provide an important building block of circular economy. This comprises the reuse of rubber from end-of-life tires for new tires, as well as saving our resources.

Tires are an important vehicle component, as car handling, safety and fuel economy depend for a major part on the tire composition and construction. As a consequence, tires are improved continuously. The most prominent improvement in the recent past was the use of a silica-silane filler system in passenger …

As a means to decrease the amount of waste tires and to re-use tire rubber for new tires, devulcanization of ground passenger car tires is a promising process. Being an established process for NR and EPDM, earlier work has shown that for ground passenger car tire rubber with a relatively high amount …

An estimated 17 million tonnes of tires are discarded annually. Re-use is achieved by retreading (9%), recycling (39%), energy recovery (37%) and landfill (5%). A preferred, but complex way of recycling is to make new tires from discarded tire rubber. Vulcanised car tire rubber has to be devulcanized …
