Pyrum Innovations, a pioneer in the sustainable recycling of end-of-life tyres (ELT) based on its patented pyrolysis technology, is deepening its collaboration with ELDAN Recycling A/S, one of the world's leading manufacturers of recycling machines, including shredders for ELT. Under the agreement, both companies will include each other's systems in their sales processes and actively distribute them.

Scandinavian Enviro Systems (Enviro) – a Swedish tire pyrolysis equipment supplier and operator – says it made a strategic recruitment by employing Fredrik Alpner as the Site Manager for the company’s plant in Åsensbruk and future plant in Uddevalla. Enviro highlights that Alpner has a long-standing background as production manager in the global processing industry and will take up a new role that will contribute to both the continued industrialization and commercialization of Enviro’s leading tire pyrolysis technology and realizing the company’s expansion plan.

The European Tyre Recycling Association (ETRA) is hosting the three day event that will take place from Wednesday through to Friday 23 - 25 March 2022 at the NH Collection Hotel, Grand Sablon, Brussels. The Conference is the culmination of a year-long series of ETRA-led and supported activities and events that focused on market development and expansion for a broad array of recycled tyre materials, products and applications.

Episode 29 of the Tyre Recycling Podcast features a returning guest Tony Wibbeler, the CEO and Founder of Bolder Industries – a renowned tire pyrolysis operator and recovered carbon black producer – who gives a thorough update on the activities of the company in the last 12 months. In the interview, Wibbeler speaks about investments by Bolder Industries in Maryville and at the former Pyrolyx plant.

Modern chemical tire recycling (pyrolysis) plants produce environmentally friendly chemical raw materials, and thus they support the overarching and specifically specified goals of the EU Green Deal and the UN Sustainable Development Goals. In addition, they can make a significant contribution to reducing GHG emissions in the manufacture of tires.

Following its traditionally successful track record, another Recovered Carbon Black Conference organized by Smithers turned out to be a great success. The conference took place on November 22-23, 2021, in Amsterdam (The Netherland). Recognized within the industry as an essential platform for experts and innovators, the program offered a 360-degree perspective of the Recovered Carbon Black market. Key industry leaders from around the world shared their expertise, case studies and latest findings.

Michelin and Bridgestone publicly announced their collaboration on developing the recovered carbon black on November 22 at the Smithers rCB Conference in Amsterdam. Sander Vermeulen of Michelin and Jake Ronsholt of Bridgestone took to the stage to discuss the role of pyrolysis in the tire recycling industry as well as the opportunities it presents. Vermeulen was apparent that pyrolysis had the potential to reduce the amount of fossil fuel utilized for virgin Carbon Black used in tires, but there were obstacles. Vermeulen was apparent that pyrolysis had the potential to reduce the amount of fossil fuel utilized for virgin Carbon Black used in tires, but there were obstacles. According to Vermeulen, many operators had demonstrated that industrial pyrolysis on a small scale could produce the needed rCB. However, when scaled up to major commercial operations, there was no uniformity and no standards, and there was a lack of consistency and specification.

The International Organization for Standardization (2008, 2013) defines chemical recycling as a production of new raw materials by changing the chemical structure of polymers (e.g., plastic, rubber) through depolymerization, excluding energy recovery and incineration. Whereby depolymerisation is understood as a reversion of a polymer to its monomer(s) or to a polymer of lower relative molecular mass. This irreversible chemical decomposition (depolymerization) in pyrolysis processes is caused solely by a rise in temperature in an inert or oxygen free environment (UIPAC, 2021).

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.
