The presence of a variety of organic and inorganic additives also underscores the complexity of the pyrolysis process by producing new substances that didn’t exist in the waste rubber feedstock (e.g., carbonaceous deposits).īased on the work of Martinez and Yu, we give a brief overview of the approaches for increasing the performance by modifying the rCB where indicated. Recovered Carbon Black (rCB) is a new category of Carbon Black, as it is a heterogeneous nanomaterial comprised of a mixture of more than one grade of virgin CB with varying ash content, particle size, morphology, surface chemistry and activity. In general, as with all products, the essential prerequisites are good and consistent product quality, constant production quantities from several thousand tons per year (the more the better), as well as an appropriate business strategy.

20% without much influence for SBR compounds (e.g.) in terms of tensile strength and tear strength. It has been shown that properly produced and processed rCB can be used as a sustainable substitute for CB N550 / N660 to the extent of approx. Besides the environmental advantages of using rCB in the rubber & tire industry, for instance that of CO2 reduction, the economic feasibility of pyrolysis is positively affected by these markets.

The first Cradle to Cradle certificate for rCB was already issued by EPEA in 2017, and most recently another rCB was accredited under the International Sustainability & Carbon Certification (ISCC) scheme. Sustainable rCB, thermochemically recovered from end-of-life tires, has already made the leap into industrial practice, and is making an important contribution to closing the loop in the tire and rubber industry.

At the same time, this article series should also be a stimulus for discussion. One of the goals is to give entrepreneurs in this industry, project initiators, investors and the public, a better insight into a rapidly growing circular economy.
