Continental to further increase the recycling share in its tires

Continental has concluded a long-term purchase agreement with Pyrum Innovations, a specialist in the thermolysis technology of end-of-life tires, for particularly high-quality carbon black (rCB) recovered from end-of-life tires. Continental intends to use recovered carbon black in the series production of passenger car tires in the future.

The two companies are thus intensifying their cooperation. The premium tire manufacturer had already signed a development agreement with Pyrum Innovations in 2022. Since then both companies share the common goal to further optimize and expand the recycling of end-of-life tires through pyrolysis.

Carbon black is an important raw material both for tire production and for the manufacture of other industrial rubber products. The use of carbon black in rubber compounds increases the stability, strength and durability of tires. Carbon black recovered from end-of-life tires helps reduce the use of fossil raw materials and CO₂ emissions. In a passenger car tire from Continental, the soot content, giving the tire its black color, is between 15 and 20 percent, depending on the model. By using recycled carbon black, Continental is one step closer to its goal of using more than 40 percent renewable and recycled materials in its tires by 2030.

“Recycled raw materials are becoming increasingly important in our tire production. To further increase the circularity of our products, we need to think differently. We need to move from an “end-of-life” to an “end-of-use” tire concept. This means that the end of a tire’s intended use phase must become the beginning of a new opportunity. Together with Pyrum, we are developing highly efficient processes to recycle as many components and materials as possible from an end-of-use tire back into our production cycle,” says Jorge Almeida, Head of Sustainability Continental Tires.
