Tire pyrolysis company from the Netherlands Black Bear Carbon has stated this month that it is ready to construct one more recovered carbon black plant at the Port of Rotterdam. However, Black Bear did not reveal the annual capacity of its anticipated facility. To recover carbon black, end-of-life tires will undergo thermal treatment at the facility as granulate will be decomposed from the waste materials. They will be further applied in production of carbon black and pyrolysis oil.

The construction of the end-of-life tire recycling plant in Sweden will be based on Enviro’s unique pyrolysis technology with the ability to extract raw materials from multi-component products. This joint venture announces the final investment decision for the construction of its first used tire recycling plant. Antin and Enviro entered into the joint venture in March of 2023 to build a series of plants in chosen European geographies.

Wastefront AS, the Norwegian waste tire recycling company, has announced a strategic partnership with innovative EV tire company ENSO, which will see ENSO incorporate Wastefront’s recycled carbon black (rCB) in its tires from 2024.

Pyrum Innovations AG (Pyrum) – a pioneer in the sustainable recycling of end-of-life tires (ELT) based on its patented pyrolysis technology – has received the ISO 14001 certification for its environmental management system following a comprehensive audit. As a result, the company now meets all the important criteria for being allowed to supply its recovered carbon black (rCB) to the automotive industry. The rCB is used in the tire industry for the production of new tires, as well as in the plastics and electrical industries. Pyrum had previously received ISO 9001 certification for its quality management system and silver status in the EcoVadis sustainability ranking. A year ago, Pyrum also signed a development agreement with premium tire manufacturer Continental to produce high quality recovered carbon black for Continental's tire production. The final hurdle has now been cleared with ISO 14001 certification.

bp has signed an eight-year offtake agreement with Circtec, a UK-based technology company that develops and operates innovative pyrolysis chemical process technology and whose plants convert hard-to-recycle waste tyres into HUPATM - Circtec’s proprietary renewable drop-in marine fuel, and circular naphtha petrochemical feedstock. Under the agreement bp is committed to purchasing up to 60,000 tonnes per year of HUPATM renewable drop-in marine fuel and up to 15,000 tonnes per year of circular naphtha petrochemical feedstock, on a take-or-pay basis, from Circtec’s new commercial-scale plant, for eight years after the new plant is commissioned.

Mars Mineral, a global provider of pelletizing technology and agglomeration solutions, has announced the shipment of a Model 26D100L stainless steel pin mixer to LD Carbon (LDC), a leading producer of recovered carbon black (rCB). LDC, based in Seoul, South Korea, will receive the pin mixer at its new manufacturing facility in Dangjin. This plant, slated to open during the second quarter of 2024, will be the largest end-of-life tire (ELT) pyrolysis and rCB operation in Asia. The Mars Mineral Pin Mixer is a high-speed, conditioning, and micro-pelletizing device that converts rCB from pyrolysis of ELTs into small spherical pellets through the action of a high-speed rotor shaft and pin assembly with the addition of a liquid binder, usually water.

Pyrum Innovations AG reports further progress in the European Union’s BlackCycle project. On 24 May 2022, the successful completion of the trial campaign was celebrated. In this campaign, various process conditions regarding the composition of ELT, the temperature profile and the residence time were first extensively researched on a laboratory scale. After successful determination of the optimal reaction parameters, several experimental campaigns on an industrial scale followed.

Mars Mineral – an American manufacturer of agitation pelletizing technology with pin agglomerators, disc pelletizers, and deep drum pelletizers based in Pennsylvania – has been awarded a contract to design and manufacture a new pin mixer for Warsaw, Poland-based Contec S.A., an environmental services company that uses pyrolysis to extract recovered carbon black (rCB) powder grades, as well as pyrolysis oil and recovered steel from waste or end-of-life tires (ELTs). The Mars Mineral pin mixer transforms the rCB powder into pellets, making them ready for packaging and transport to Contec’s end-partner customers. rCB pellets are used in tire, paint, plastics, and rubber manufacturing.

Sometimes it makes sense to periodically sift through your personal library (even though that's primarily done electronically these days). When you browse around, some things come to light that are worth not forgetting, such as a conference paper that was published exactly 30 years ago in August 1993. “A multiple-product approach to the processing of used tires” (Michal A. Serio, et al., 1993) is a remarkably accurate vision of chemical recycling of end-of-life tires (ELTs), as it is experiencing a boom in the last few years. The authors presented their well-founded proposals for sustainable recycling of ELTs through pyrolysis at a conference of the American Chemical Society (ACS Division of Fuel Chemistry) in the USA. About 20 years later, namely in 2011, the United Nations Environmental Program (UNEP) within the framework of the Basel Convention (191 signatory states) approved the chemical recycling of ELTs by pyrolysis as Environmental Sound Management (ESM). This classification was subsequently also included in the European regulations. In this exposé of the remarkably visionary work, the original text is quoted and only occasionally an outdated term is replaced by the one used today. Replacements and comments are in Italic. This paper by Michal A. Serio and colleagues could just as well have been written today.
