ExpertTalk | Recovered Carbon Black processing

The Hosokawa Group has developed a process for the sustainable recovery of Carbon Black from used car tyres. By performing a number of steps after pyrolysis, the process results in dust-free granular material that can be dosed accurately. It is ready for immediate use in the manufacture of new car tyres or other rubber-based products.
Many recycling companies that handle car tyres are keen to find a way to recover Carbon Black from the rubber. This 'black gold' must undergo several processing steps after pyrolysis before it can be used as recovered Carbon Black (rCB). "We've developed an efficient and sustainable process for that," says Marc Jacobs, Team Manager Chemicals, Minerals & Metals (CMM) at Hosokawa Micron in Doetinchem, the Netherlands. "Our new processing line makes it easy for recycling companies to recover top-quality Carbon Black from car tyres. Manufacturers of car tyres and other rubber-based products can then immediately use the resulting granules in their production processes."

Is your rCB in specs for the tire manufactures

[@vonwolfersdorff]

@gerhardpretoriusg The tire manufacturers do not yet have a public unified rCB specification, although the "rCB Rubber Project" by Bridgestone and Michelin has started work on product categories and suitable certificate of analyses data. Clearly, there is more to controlling rCB quality than just the back-end process: The end-of-life-tires need to be selected, cleaned and mechanically deconstructed, the tire pyrolysis process needs to be controlled and only then the rCB treatment process can do its work to produce a good rCB.
