Nokian Tyres has entered into a research agreement for an international project with the aim of enhancing the quality and yield of recycled carbon black derived from end-of-life tires. The objective is to enable greater utilization of recycled carbon black in rubber compounds, providing tire and rubber manufacturers with the opportunity to create more sustainable products. Carbon black serves as a reinforcing filler in tires, enhancing their physical properties such as strength and resilience. Recycled carbon black can partially replace fossil-based virgin carbon blacks, contributing to a more sustainable approach.

As per the latest press release by Nokian Tyres, the company has made a long-term purchase agreement with a tire recycling joint venture. The agreement will help Nokian Tyres reach one of its key sustainability targets, which is to increase the share of recycled and renewable raw materials in tires to 50% by 2030. Nokian Tyres started to use recovered carbon black in a commercial product line in 2022. The long-term purchase agreement with a tire recycling joint venture enables its increased utilization in tires accelerating circularity and sustainability in the tire industry.

On July 30, 2024, Pyrum Innovations AG (Pyrum) and Continental signed a framework agreement for the long-term purchase of Pyrum’s recovered Carbon Black (rCB). The agreement covers the rCB purchase quantities for at least two Pyrum plants, with a term of ten years. Continental will also supply Pyrum with end-of-life tires. In addition, Continental has agreed to make an advance payment for future rCB deliveries.

Continental continues to step up its activities to ensure a circular economy. Recently, the tire manufacturer added recovered carbon black (rCB) to its newly produced Super Elastic solid tires at its tire plant in Korbach, Germany, thus reducing the use of fossil raw materials and CO2 emissions. Solid tires such as Continental’s SC20+ already contain around 60 percent renewable and recycled materials thanks to their high natural rubber content. By 2050 at the latest, Continental aims to use 100 percent sustainable materials in its tire products.

Recycled carbon black, crucial for tire stability and durability, helps reduce reliance on fossil fuels and lower CO2 emissions. Continental is committed to a closed-loop recycling system, where end-of-life tires become raw materials for new products, aligning with its long-term sustainability strategy to achieve 100% sustainable materials in tires by 2050.

Pyrum Innovations AG, in collaboration with Schwalbe, has reached a significant milestone in their tire recycling program, with 1,000,000 bicycle tires successfully collected, recycled, and reintroduced into the material cycle. This achievement highlights the effective partnership between the two companies in advancing sustainable solutions within the circular economy.

Pyrum Innovations AG (Pyrum), a pioneering company that recycles end-of-life tires sustainably with its globally patented, unique pyrolysis technology, and the bicycle tire manufacturer Ralf Bohle GmbH (Schwalbe brand) have developed the world's first bicycle tire made from recycled tires. Pyrum's Green Marathon uses 100% recycled carbon black (rCB), which is a direct product of the recycling process and replaces fossil carbon black. The production of the innovative bicycle tire saves more than a third of CO2eQ compared to the previous model. To determine the CO2 savings, a detailed Product Carbon Footprint (PCF) of both models was calculated and evaluated according to the current IPCC AR6 standard (GWP 100, excl. biogenic CO2).

On the 6th of February, American Society for Testing and Materials (ASTM) announced opening a committee which will develop standards for the recovered carbon black (rCB). The goal of the ASTM’s new committee D36 will be to establish and update standards in end-of-life tire (ELT) and scrap rubber decomposition, standards in material characteristics and sustainability. ASTM declared that the committee will be formed and governed by the members of its existing committee on carbon black (D24) who engaged in working with a vast portfolio of standards on recycled carbon black goods.

According to its latest press release, Ecolomondo Corporation – a Canadian cleantech company specializing in the commercialization of its Thermal Decomposition Process (TDP) proprietary recycling technology and building and operating turnkey TDP facilities globally – announced that it has secured an offtake agreement for up to 80% of its Recovered Carbon Black (rCB) production from the Company’s Hawkesbury TDP facility.
