A special committee on recovered carbon black (rCB) at ASTM International has introduced its first standard defining conditions for the rCB industry. The standard comes at a time when carbon black is still viewed as somewhat new recycled merchandise that the expanding commercial tire and plastics sectors are using, one of the ASTM members pointed out.

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.

HITEC Luxembourg participated in Recovered Carbon Black Asia 2026 in Bangkok, Thailand, marking the company’s first appearance at the Asian edition of the industry event. Over two days, the company engaged with more than 200 professionals from across the recovered carbon black value chain and demonstrated its Individual Pellet Hardness Tester, or IPHT, as a tool for evaluating pellet quality and consistency. HITEC emphasized that reliable batch-to-batch performance remains one of the central requirements for broader commercial adoption of recovered carbon black in tire, rubber and other industrial applications. The company also used the event to strengthen cooperation with regional partners CG Engineering in Thailand and Highest Instruments in China, reflecting growing demand in Asia for quality control, laboratory testing and process monitoring technologies supporting recovered carbon black production.

As recently reported by ERJ, the British technology startup HiiROC entered into a memorandum of understanding with Tokyo Gas to explore the deployment of its thermal plasma electrolysis technology for the production of clean hydrogen and sustainable carbon black.

Scandinavian Enviro Systems (Enviro) – a tire pyrolysis equipment manufacturer and operator based in Sweden – and its partner Michelin – one of the global leaders in tire manufacturing – have presented another sustainable racing tire based on recovered carbon black from Scandinavian Enviro Systems. The new tire is a high-performance tire developed for racing cars and was recently presented at Michelin’s Movin’On global sustainable summit. According to Enviro, the new tire contains 46 percent renewable and recovered material, including recovered carbon black delivered by Enviro to Michelin. Michelin presented the new high-performance tire mounted on the electric-hydrogen, long-distance racing car, GreenGT Mission H24. Earlier this spring, Michelin also presented a sustainable racing tire for MotoE, a racing series for electric motorcycles, which also contained recovered carbon black from Enviro. Michelin has announced the goal that all its tires will be manufactured entirely from sustainable material by 2050.

As part of an ongoing strategic review, Cabot said it will cease operations at its reinforcing carbons facility in Campana, Argentina, while also discontinuing production on several manufacturing lines in the Netherlands.</p><p>According to the company, the restructuring measures are intended to better align production capacity with current market conditions while improving long-term cost competitiveness.

Orion S.A., a global specialty chemicals company, announced that it has signed a long-term supply agreement with Contec S.A., which will provide Orion tire pyrolysis oil to produce circular carbon black for tire and rubber goods customers. The agreement with Warsaw, Poland-based Contec further enables Orion to diversify its sources of tire pyrolysis oil, commonly known as TPO.

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.

On 7 July, Newcastle University and Wastefront announced their partnership that will focus on the characterisation and enhancement of Wastefront’s recovered carbon black (rCB). As one of the UK’s top universities and a world leader in sustainability, Newcastle University’s partnership with Wastefront will see cutting-edge industry innovation emerge from research conceived in the North of England - ensuring the region is at the forefront of progressing circularity across Europe.
