Scrap tyres recycling at Roth International

UNTHA shredder for all kinds of scrap tyres

Scrap tyres – whether from wheelbarrows, cars, or trucks – must withstand high loads, which is why they are made of particularly resistant materials such as natural rubber, steel, and nylon. All these materials form a complex, durable compound. In order to make good use of used tyres at the end of their service life, for example in recycling, pyrolysis processes or as an alternative fuel, they must be shredded and broken up into their individual components.

To handle this process as efficiently as possible, ROTH International GmbH puts its trust in UNTHA’s XR3000C mobil-e. Its benefits: the shredder saves time thanks to a single-phase process, lowers energy costs with the economical UNTHA Eco Power Drive and produces a homogeneous output.


Conclusions of the customer

“With the UNTHA XR3000C mobil-e, we shred scrap tyres in a single-step process. The highly efficient shredding process and the economical UNTHA Eco Power Drive lower our overheads and help increase our economic viability. Thanks to the XR, we now achieve the output that used to require two shredders with just a single one”, is how Michael Roth, Managing Director of ROTH International GmbH, sums up the advantages offered by the UNTHA shredder.


Resource-saving use of scrap tyres

Scrap tyres constitute a problem for waste management and recycling. It is estimated that approximately 17 million t of scrap tyres are produced every year, 600 000 t in Germany alone. To recycle tyres and rubber in an environmentally friendly, resource-saving manner, special processes are used: pyrolysis technology, material recycling, and the production of alternative fuels.

As a certified specialist disposal firm, ROTH International is synonymous with environmental awareness and sustainability. The company employs innovative procedures and technologies to make processes more efficient and to fully use waste materials such as scrap tyres.


UNTHA XR3000C mobil-e cuts to the chase

Every year, ROTH International processes approx. 4000 t of scrap tyres for pyrolysis technology and the production of alternative fuels, from tiny wheelbarrow wheels to supersize construction machinery wheels. The goal is to make the best possible use of the resources contained in the tyres while working as energy-efficiently and economically as possible.

“Due to their composition (rubber/textile mesh), scrap tyres are difficult to shred. They require a shredding solution with a high torque and an exact cutting gap that produces a highly defined grain. This is important because metal wires that have not been cleanly cut pose a problem for further processing, as they may get caught and cause issues down the line,” says Daniel Wresnik, Team Leader XR/ZR Sales & Demonstrations DACH Region at UNTHA shredding technology GmbH.

ROTH International chose the UNTHA XR3000C mobil-e: a slow-running, single-phase shredder that does the job that used to require two machines. Thanks to the energy-efficiency of the UNTHA Eco Power Drive (drive system with water-cooled synchronous motors) and its highly reliable shredding performance, this shredder is particular cost-effective and economical. The C-cutting system (cutter) shreds scrap tyres down to a fraction size of approx. 50 mm in just a single step (according to the fitted screen size). The unit has a throughput of around 4.5 to 7 t/h, depending on the state of the material and its composition. Using a magnet separator that is installed above the conveyor belt, metal parts are removed from the material and reintroduced into the resource cycle. The shredded tyres are ideal for use in pyrolysis processes or alternative fuel production.
