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.

Continental continues to step up its activities to ensure a circular economy. Recently, the tire manufacturer added recovered carbon black (rCB) to its newly produced Super Elastic solid tires at its tire plant in Korbach, Germany, thus reducing the use of fossil raw materials and CO2 emissions. Solid tires such as Continental’s SC20+ already contain around 60 percent renewable and recycled materials thanks to their high natural rubber content. By 2050 at the latest, Continental aims to use 100 percent sustainable materials in its tire products.

On 7 July, Newcastle University and Wastefront announced their partnership that will focus on the characterisation and enhancement of Wastefront’s recovered carbon black (rCB). As one of the UK’s top universities and a world leader in sustainability, Newcastle University’s partnership with Wastefront will see cutting-edge industry innovation emerge from research conceived in the North of England - ensuring the region is at the forefront of progressing circularity across Europe.

South Korean waste treatment and raw material recycling company LD Carbon (CEO Baek, Seong-mun and Hwang, Yong-kyung) announced that it had signed an MOU with Japan’s Sumitomo Rubber Industries, Ltd. for the commercialization of sustainable tire raw materials.

Business Wire recently reported that Bolder Industries (“Bolder”), a pioneer in converting end-of-life tires into sustainable industrial products such as recovered carbon black (rCB), and Continental Carbon Company (“CCC”), a leader in the development and manufacture of furnace-grade carbon blacks for the tire and rubber industry, announced on November 17 that they have entered into a co-marketing agreement to commercialize breakthrough, sustainable products for the global rubber and plastics industry.

US-based Bridgestone announced recently that it has commenced producing tires containing carbon black (rCB) at its facility in Des Moines. In tire production, the company relies on carbon black supplies from its partner Delta-Energy, and uses its product, D-E Black, as the only source of the recycled material. Currently, Bridgestone has bought some 215 metric tons of Delta Energy’s rCB – this is the equivalent of over 60,000 scrap tires. By the end of next year, the company expects to apply around 6,800 of D-E Black, which would reduce over 20 million pounds of carbon emissions.
