Recovered
First Generation
The most basic technology for recycling rubber converts end-of-life tire and post-industrial rubber material into rubber chips that
are typically one inch or larger in size. These chips are then used in tire-derived fuel and civil engineering projects
Second Generation
GTR
Second-generation processing technology converts the end-of-life tire and rubber material into crumb rubber—also known as
tire granulate, or ground tire rubber (GTR). This crumb rubber is typically comprised of chips between one inch and 30
mesh in size, with the associated fiber and steel mostly removed. Crumb rubber applications are nonetheless limited because
of the chips’ relatively large size. The material is used in asphalt, as garden mulch and in playgrounds.
Next Generation
The last evolution Micronized rubber powder (MRP) is classified as fine, dry, powdered elastomeric crumb Rubber in which a
significant proportion of particles are less than 100 µm or 80 mesh and even down to 300 mesh. Unlike other technologies,
MRP is virtually metal and fiber-free, enabling its use in a wider range of advanced products. These applications include highperformance tires, plastics, coatings and roofing systems

Devulcanization or Degradation
Experimental
Preparation of the RGTR
GTR and soybean oil were
mixed with different ratios
The mixed samples were
degraded in a hot-air (at 150 C
for 4 h.
Remark
The reclaimed GTR was labeled
as the RGTR.
The content of the soybean
oil of 20 parts per hundreds of
rubber (phr) in the RGTR was
labeled as RGTR20.
