Carbon Black is the main product recycled by Pyrolysis technology. The amount of recycled carbon black is 35% (depending on the type of tyres) of the total amount of scrap tyres feeded in the system.

It can be used as a fuel source by pressing it into briquettes. Once pressed into briquettes it produces much higher Btu's and leaves less than 3% in ash after burning it, which means that it can be used as a clean burning alternative (substitute coal). Carbon black produced from the pyrolysis of waste tyres can be used in almost any application that ‘virgin’ carbon black (VCB) may be used such as tire production, rubber compounding, pigments, coatings, etc. Some specialized applications of recovered carbon black (RCB) may require additional processing after pyrolysis to yield specific particle sizes; however, there are many applications for carbon black recovered from waste tyres that require little, if any, post processing of the material.
