Pyrolysis is a thermochemical pathway to treat vulcanized rubber for the recovery of valuable products. It involves the decomposition of the rubber at high temperatures (400 – 900°C) in the absence of an oxygen atmosphere. The main products of pyrolysis are a solid fraction, usually raw carbon black (according to ASTM D8178); a liquid fraction comprised of light oil, heavy oil, and tar; and a gas fraction.

The innovation forum "Scrap Tire Recycling" (AZuR) sponsored by the Federal Ministry of Education and Research of Germany recently published a large-scale study for its partners. The study is focused on the market positions and requirements of end-of-life tire recyclers and manufacturers of products from recycled tire rubber. Below, we are citing the original article published on the website of AZuR in May 2021. To read the original text in German, please proceed to AZuR’s website.

e-RubberCon is an international conference organized by the French Association of Rubber and Polymer Engineers (AFICEP) under the auspices of the International Rubber Conference Organization (IRCO) which AFICEP is a member of. As its name suggests, the conference is devoted to problems of rubber industry, including rubber and tire recycling, as this year its main motive is “Environment and Recycling: A Strategic Challenge for Rubber Materials.” This year, Robert Weibold – a tire recycling and pyrolysis expert from Vienna, Austria – speaks at e-RubberCon about “Challenges, trends and opportunities for end-of-life tires from a French perspective”. If you would like to connect with Robert Weibold, please send your inquiry at sales@weibold.com.

Today, fast-paced technology advances in IoT and digitalization have been affecting almost all industries. One might think that tire recycling and pyrolysis industries are far beyond the scope of this trend. Yet, quite the opposite is happening. Below, we will explain how tire recycling and pyrolysis plant operators will be embracing effects of advancing tire manufacturing technologies.

Recently, an expert in tire-derived carbon black Martin von Wolfersdorff shared his views on the prospects recovered carbon black (rCB) in tire-to-tire recycling. In his press release Mr. von Wolfersdorff said he appreciated it when tier one carbon black companies spoke about rCB. The expert says top carbon black producers attend rCB workshops, presentations or conferences organized by Wolfersdorff Consulting, and there are ample opportunities for collaboration between the rCB and the CB industry, some of which have been highlighted in his Carbon Black World 2018 presentation in Düsseldorf (see image below). There is way to go, Martin von Wolfersdorff says.

With recycling and sustainability making headlines in the mainstream news, recovered carbon has ever growing market potential. Its enhanced use would lead to reduction of CO2 footprint, cost reduction to carbon black users, less price volatility and even in some cases performance benefits over carbon black grades. It is used as a substitute for virgin carbon black, or applied in combination with its virgin counterpart; the research of the recycled material’s applications, its blending properties and value is still ongoing, and it was deeply discussed during Recovered Carbon Black Forum held on May 21-22 in Berlin, Germany organized by Smithers Rapra and Martin von Wolferstorff.

Napajedla stud farm (Czech Republic) which is 130 years old is one of the best facilities in Europe. This stud farm brought up several famous winners and it bears a number of success stories in its history. Horses which were raised at the farm won races not only in Czech Republic and Slovakia, but also showed remarkable success in competitions in Germany, Austria, Switzerland, France and Great Britain.
