The yields of pyrolysis oil, pyrolysis carbon black, pyrolysis gas, and steel wire are 45%, 34%, 9%, and 12%, respectively. It is assumed that the scaling effect does not impact the distribution of product yields, meaning that the product yields for the 200,000 tons/year processing scale are the same as the aforementioned values.

All three products including pyrolytic carbon black (CBp), tire pyrolysis oil (TPO) and pyrolysis gas showed good characteristics. Pyrolysis gas had been successfully re-used for pyrolysis furnaces and dryers. The higher heating value of TPO estimated to 37–40 MJ/ kg, which was comparable to diesel fuel through further treatment.
