Continental and Pyrum partner to power recycled carbon black usage

The partnership aims to optimise and expand recycling of end-of-life tires through pyrolysis, reducing the use of fossil raw materials and CO2 emissions.

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 have shared the common goal of further optimising and expanding 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 colour, 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.

Jorge Almeida, Head of Sustainability at Continental Tires, said, “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.” 

Continental tires already contain recycled materials such as recycled rubber from mechanically processed end-of-life tires, recycled steel, and recycled polyester from PET bottles, which otherwise often end up in incinerators or landfills.

Tire recycling requires advanced technologies and processes to efficiently separate, clean, and recycle materials without compromising the safety or quality of the recycled tires or materials. Safety is Continental’s top priority.

Pascal Klein, CEO of Pyrum Innovations, said, “The premium tire manufacturer previously concluded a development agreement with Pyrum Innovations in 2022. The expansion of our cooperation with Continental is a very important step for us. To ensure that Continental can also use our recovered carbon black in the series production of passenger tires in the future, we are continuously working on its further development as part of a development partnership. Together, we have already succeeded in ensuring that all newly produced forklift tires at the Continental tire plant in Korbach, Hesse, contain our sustainable carbon black.”

The circular economy is an integral part of Continental’s sustainability strategy. As part of its ambitious sustainability strategy, Continental aims to increase the use of sustainable materials in its tires to 100 percent by 2050 at the latest. Recycled materials will make an important contribution. As part of a closed-loop system, end-of-life tires will become the raw material for new tires in the future.
