Our mission is to promote new uses of exhausted tyres and spread correct information to show everybody all of their intended purposes.
Did you know that every year Italians take off of their transportation means about 350 thousands tons of exhausted tyres? The recyclable materials can be used to build football pitches, modified tar, gaming areas for children and many other ways in the construction industry. You should think before you leave your old tyres down on the street. First of all, remember it’s a serious violation, but don’t forget they can become football pitches or kilometre-long streets.
Modified asphalts: in Italy there are 300 km of streets and bike lanes made by crumb rubber. These asphalts ensure a conspicuous noise reduction (until 7 Db), a better resistance to cracks, a more efficient water drain and a triple duration, if compared to conventional ones. What improves the most? The drivers’ safety, of course.
Sport pavements. Flexibility and impact absorption are two features which allow the crumb rubber to be used to build football pitches (no irrigation nor treatments are needed), running tracks, equestrian sports pavements and playgrounds with injury protections. The economic advantages are evident.
Acoustic isolators and anti-seismic materials: since 2006, an EU regulation prevents from dumping, starting to consider the exhausted tyres as a resource, not waste anymore. Corgom is a qualified and honest company that got to be one of the main characters in southern Italy recycling.
The 2014 balance sheet showed that our policy led us to great results, as proved by Unirigom (Union of exhausted tyres Italian re-treaders).
In 2015, the 45% of exhausted tyres collected in Italy (146.725 tons) has been recycled and the remaining part has been used for energy production.
Exhausted tires re-treaded step by step
Step n.1: Storage
Storage
Once taken off of cars and trucks, exhausted tyres are collected from garages and tyre shops. After, they are transported to the sorting facility, where they undergo weight and separation operations. Finally, they are stored in an appropriate place, waiting for the treatment.
Step n.2: De-beading
De-beading
It’s the first treatment step and it consists in removing the steel ring near the bead. The bead is the closest part to the wheel rim. After removing, the ring can be recycled in steelworks and foundries. This step happens only for trucks tyres.
Step n.3: First chipping
First chipping
The exhausted tyres are chipped in small pieces – called ‘chips’ between 5 and 40 cm. The chips still contain small textile or metallic fragments. After, the recycling process can start or the chips dimension can be reduced.
Step n.4: Second chipping
Second chipping
The tyre is chipped once again to obtain a subtle powder, very useful for the recycling process.
Step n.5: Material recovery
Material recovery
Different size materials are the result of the previous steps. Not only rubber is recovered, but steel and textile as well.

Exhausted tyres disposal is one of the main environmental problems. Their materials, indeed, are barely biodegradable.
We decided to overcome this problem by choosing the new tyres recycling policy, according to the 82/2011 ministerial decree.
Thanks to hi-tech machines, the exhausted tyre can be recycled to recover several resources, such as new energy, modified tracks, sport grounds or isolating materials.
