Project Description

Granulated and Powder Rubber

For the production of rubber granules and powders TerniEnergia uses an innovative technology that provides a first phase of volumetric reduction of the out-of-use tire and subsequently a mechanical grinding phase at room temperature. The generated material is subsequently sifted and cleaned to obtain a perfect separation of the steel, the textile fiber, the powder and the rubber granule of the different granulometries. The cleaned granulate is packed in big-bag, the loose steel is collected in roll-off trucks for transport in steel mill and the textile fiber collected for off-site energy valorization.

The following separation result is obtained from the tire processing step:

15% 0,2 – 0,8 mm 20%

0,8 – 2,5 mm 20%

2,5 – 4 mm 20%


Depending on the composition of the input material, the percentages may vary.
The main uses for the powder and rubber granules deriving from PFU are:

Modified asphalt
Sports surfaces
Insulation material
Urban furniture, floors and artefacts
Civil Engineering Works
Reuse in mix
The TerniEnergia powder and granulate complies with UNI CEN / TS 14243: 2010


The main uses of ELT’s rubber powder and granules are the following:
  • Modified Asphalts
  • Sports surfaces
  • Insulation material
  • Urban furniture, floors and artefacts
  • Civil engineering works
  • Mixture reuse
