Pirelli, Pyrum, Synthos and BASF have launched a “tyre‑to‑tyre” project, coordinated by Pirelli, to advance circularity and reduce reliance on virgin raw materials.

The process draws on end‑of‑life tyres collected across Germany, from some Driver retail outlets and motorsport activities, as well as scrap tyres collected from Pirelli’s Breuberg plant.

Pyrum converts end‑of‑life and scrap tyres through a pyrolysis process — a high-temperature thermal decomposition of materials in the absence of oxygen — into two valuable secondary raw materials: recovered carbon black (rCB) and tyre pyrolysis oil (TPO). The recovered carbon black is upgraded in quality and directly reintroduced into Pirelli’s European production, partially replacing virgin carbon black.

the TPO is supplied to BASF, where it is co-fed with fossil-based feedstock into the production process of chemical products such as butadiene and styrene. A mass balance approach enables attributing the recycled content to the ISCC PLUS-certified Ccycled® products. These circular materials are then used by Synthos to produce ISCC PLUS‑certified synthetic rubber for high-performance tire applications, which Pirelli reintroduces into its production processes, closing the loop.
