A new study from Nigeria has examined the microstructural and elemental properties of recovered carbon black (rCB) produced through pyrolysis of waste tires at 400°C, 500°C, and 600°C. The findings suggest that pyrolysis at 400°C for two hours yields the most favorable balance between carbon content and material structure, making it particularly promising for industrial reuse.

Orion S.A. reported first quarter 2025 results showing a decline in revenue and earnings, impacted by lower oil prices, unfavorable exchange rates, and unplanned plant downtime. Net sales fell to $477.7 million (down 5% YoY), and adjusted EBITDA dropped 22% to $66.2 million. While volumes rose in the Rubber Carbon Black segment, Specialty Carbon Black demand softened in the Americas.

German end-of-life tire pyrolysis operator Pyrum Innovations AG (Pyrum) has started series delivery of recovered carbon black (rCB) to Ralf Bohle GmbH, manufacturer of German bicycle tire brand Schwalbe. According to Pyrum, the delivery will close the loop “completely” for Schwalbe, which collects end-of-life tires through its recently launched recycling system and supplies them to Pyrum for further processing.

On November 20, Pyrum Innovations AG (Pyrum) received the unlimited delivery approval from Continental for the Pyrum recovered Carbon Black (rCB) of the plant in Dillingen/Saar. As part of the Continental audit, Pyrum successfully carried out the process capability analysis for the two new lines in recent weeks. The analysis serves to evaluate the short and long-term process stability. The values determined show a long-term capability (Cpk) of 2.16 for TAD 2 and 2.70 for TAD 3 as well as a short-term capability (Ppk) of 2.49 (TAD 2) and 3.38 (TAD 3). The results are above the required standard values specified by the automotive industry (Cpk: 1.33; Ppk: 1.67).

Ecolomondo Corporation – a cleantech company specializing in the commercialization of its Thermal Decomposition Process (TDP) proprietary recycling technology and the global deployment of TDP turnkey facilities – announced that Reactor 1of its 2-reactor TDP plant in Hawkesbury, Ontario, has been certified by TSSA (Technical Standards and Safety Authority) for the use of the syngas (process gas) produced from TDP production cycles as the energy source to fire up reactors.

Ecolomondo Corporation, a leading innovator in sustainable tire recycling technology, announces that it expects to soon receive its new milling line. As previously announced, the Company was in the final stages of the commercialization of its Hawkesbury TDP facility when it discovered a major deficiency in its recovered carbon black milling line that was already installed. After numerous months of testing, the milling line was incapable to achieve the promised output of 1,600 lbs per hour of recovered carbon black (rCB) nor was it capable to yield a particle size of 10-15 microns, the particle size promised and required by most of the Company’s rCB off-takers.

Pyrum Innovations AG (Pyrum), a pioneer in the sustainable recycling of end-of-life tires based on its patented, unique pyrolysis technology, announces the first delivery of recovered carbon black (rCB) to Ralf Bohle GmbH with its Schwalbe brand. The rCB is obtained from used bicycle tires that Schwalbe collects from specialist dealers throughout Germany with its "Schwalbe Recycling System". Subsequently, Pyrum with its pyrolysis plant in Dillingen takes over the mechanical processing as well as the pyrolytic recycling of the used tires. Thus, Schwalbe is now starting production of the first bicycle tire to use rCB completely. The tire is to be presented in June 2023 at the world's largest bicycle trade fair Eurobike in Frankfurt and will then be available in stores.

Carbon Black is produced by burning fossil fuels, however the market is shifting as the rubber and plastics industries turn to tire pyrolysis as a source of recovered Carbon Black. Smart Tire Recycling (STR), based in Pittsburgh, says that their innovative method yields recovered Carbon Black (rCB), which is equivalent to virgin Carbon Black used in tires. Pyrolysis, which needs high temperatures to transform materials into liquid in the absence of oxygen, has been the primary technology for producing rCB until now. Despite a long history of research and development, meeting the criteria and needed properties for usage as a CB replacement has remained a challenge.

The Intellectual Property Authority of the European Union (EUIPO) recently approved a trademark EnviroCB which belongs to the company Scandinavian Enviro Systems. Enviro is the first company in the world which commenced supplying recycled carbon black (rCB) to the premium segment of automotive industry. Now that the trademark has been registered, Enviro has a chance to deliver rCB to other markets and industries to substitute virgin carbon black.
