Material for processing
Tyres are 100% recyclable. Their chemical and physical properties make them a valuable resource. Many of the characteristics that are benificial during their on-road life are equally advantageous when tyre based granules are used as raw materials in applications and products. The principles advantages of these materials are their elastic behaviour, good mechanical strength, resistance to heat, humidity, sunlight and ultra-violet rays and an excellent price-quality ratio.
Re-Tyre processes truck and car tyres on two separate production lines.
The composition of both tyres is different.
As a result the composition of both car- and truck tyre based granules are different, but from a chemical point of view not considered as significant.

Process info
The carefully selected tyres are shredded to pieces of 150 x 250 mm. These rubber shreds are ground into particles of 0 – 30 mm. Steel is removed by using magnetic separators.
The next step is the sieving of the rubber particles into different sizes. Particles > 7 mm are feed back to the grinder. Finally remaining steel, textile fibers and other various heavy particles (like stones and glass) are extracted. The final products are packed into by customer desired packaging.
