Carbon black recycled from car tires

Research News /

Until now, waste tires have been used mainly for recovering energy sources: Only small proportions of the carbon black contained in these tires are recycled, since mineral ash accounts for around 20 percent of its content. A new process developed by the Fraunhofer Institute for Building Physics IBP is able to isolate almost all of this ash – allowing both the carbon black and the minerals from the ash to be reused.
