Gomma To Gomma, An Italian Project That Makes Used Tires Reborn From Their Ashes

Gomma to Gomma

Ecotyre announces the second phase of the project to manufacture tires with a recycled rubber content greater than 20%.

Like the phoenix, tires can also be reborn from its ashes. Or, more precisely, from its granules. This occurs in Italy, where the EcoTyre consortium has conceived and developed the Gomma to Gomma project. The initiative, as you can guess, aimed to close the circle of tires at the end of their useful life, turning waste into a new resource for the same supply chain.

We thought about this project just three years ago, setting ourselves the goal of seeking a new future for rubber – explains the consortium – and we were supported by important partners who immediately believed in this turning point.

We have designed ecological tires through the integration of the Good Practices identified in the different phases of the recovery chain.

The consortium first selected the residues and crushed an ELT granulate; the latter was devulcanized to obtain usable rubber again. From here, an innovative compound was studied and developed.

The final product is a tire that currently contains 20% recycled rubber resulting from the treatment of ELTs, tested in recent months on 20 trucks and with a total distance of over 1.5 million kilometers. Each vehicle, loaded with maximum payload, was equipped with traditional tires on one side of the drive axle and recyclable tires on the other.

The results were surprising: the new tires with 20% recycled and devulcanized rubber showed similar characteristics, and in some cases better, durability and resistance than conventional tires.

Given the success of the project and above all the interest shown by Italian and foreign manufacturers, EcoTyre and its partners decided to extend the test to at least 100 vehicles from the ELT collection fleet with the launch of Gomma a Gomma 2.0. The new initiative will include a new percentage increase in recycled rubber, and the expansion of the project to other types of tires.

We are increasingly convinced that this is the right path for the future of tires and the circular economy.
