The oil and recovered carbon black that Scandinavian Enviro Systems (Enviro) produces from end-of-life tires in its plant in Åsensbruk have been accredited under the International Sustainability & Carbon Certification (ISCC) scheme. The information comes from the recent press release by the company. In doing so, Enviro has become – reportedly – the first company in the world to receive ISCC certification for recovered carbon black, and the certification is also confirmation of the previously communicated higher commercial values of both carbon black and oil.

End-of-life tire recyclers and retreading companies will be able to compete in several nominations next year as part of the 2022 Recircle Awards that praise sustainable businesses, recycled tire rubber products and management teams in the tire recycling sector. The winners will be announced on April 25.

This article deals with the question of whether the scientific recommendations for the development of new modification methods for upgrading recovered Carbon Black (rCB) derived from end-of-life tire (ELT) pyrolysis have not already been (partially) overtaken by industrial practice. This question does not mean that the extensive research on rCB is unnecessary. Quite the contrary! Past and new research results were and are of priceless value for the development of new ASTM approved characterization methods to be able to predict rCB performance in rubber applications in a practical and science-based manner.

Episode 25 of the Tyre Recycling Podcast features the Director of the Recycling Committee of SLTC – Emanuel Bertalot. SLTC – Sociedad Lationamericana de Tecnología del Caucho – is the Latin American Society of Rubber Technology, it brings together professionals, academics and businessmen from the sector. With partners distributed all over the planet, an online magazine and dozens of conferences and courses throughout the region, we are committed to technological, entrepreneurial and management knowledge in the field of the rubber industry.

On August 5, 2021, a press release by McDermott International informed announced the company has been awarded a Front-End Engineering Design (FEED) contract from the Michelin Group in France for an innovative waste tire technology enabling large-scale production of recycled carbon black—a key ingredient in advancing the next generation of sustainable tires. This award follows a similar FEED announcement in April, which is focusing on the production of regenerated styrene to make synthetic rubber for tires. Incorporating Scandinavian Enviro Systems' licensed pyrolysis process, a technology that separates bulky waste into raw materials for repeated production, the implementation of this waste-to-value solution further advances Michelin's commitment to building a circular economy and increasing the demand—and availability—of sustainable materials.

A German recycler Stadtwerke Osnabrück has revealed plans to construct a tire pyrolysis plant that will consider sustainability principles and process 100 percent of scrap tires in the Germany city of Osnabrück. The plant will be given a name of Pieswerk, and it will rely on a special thermo-chemical process of pyrolysis during recycling. This will help to recover raw materials from scrap tires. The Stadtwerke supervisory board has already given the "green light" to pursue the Pieswerk plans. Stadtwerke CEO Christoph Hüls stressed that the project is still undergoing early stages but his company wanted to make the information public in order to be transparent. He also emphasized that pyrolysis is not well-known among the public but this process “has proven itself many times and that many will certainly also use at home – for self-cleaning of the oven."

This article should give an overview over the recent development trends regarding the options for an upgrade of the tire-derived oil (TDO) with chemical and physical techniques. In two previous articles we have already dealt with the production of limonene and highlighted the advantages of fractional distillation of TDO. Introduction Refiners around the world are looking for alternatives to producing fuels from petrochemicals only. This is due to expected future declines in crude oil reserves combined with significant fuel demand growth expectations throughout the world and increasing environmental awareness among the population.

Black Bear Carbon (“BBC”), the Dutch technology provider for recycling end-of-life tire rubber into recovered Carbon Black (rCB) and renewable petrochemicals, has announced that is had successfully completed a first closing of €7.5M , this is the first step in a fundraising campaign of €78M for its new BBC flagship plant at Chemelot Industrial Park, the Netherlands. The investment round was led by Capricorn Partners from the Capricorn Sustainable Chemistry Fund, with support from Invest-NL, joined by current investors; Brightlands Venture Partners, Siam Cement Chemicals and others.

Orion Engineered Carbons S.A. (NYSE: OEC), one of the leading global suppliers of specialty and high-performance carbon black, has partnered with RISE Research Institutes of Sweden in a project to develop and produce renewable carbon black (rCB). This collaboration represents an important step towards more climate-neutral carbon black production by replacing traditional carbon black feedstock with pyrolysis oil from biomass oil. Orion plans to convert the biomass oil into carbon black using its small-scale furnace reactor in Kalscheuren, Germany and will explore ways to upscale the process to match market demands. Additionally, using a pilot-scale reactor at its site in Piteå, Sweden, RISE will evaluate the use of electrofuels, such as plasma or hydrogen from electrolysis, as sustainable heat sources for the carbon black process.
