The first industrial-scale pyrolysis plant for solid tire wastes has been installed in Jenin,northern of the West Bank in Palestine, to dispose of the enormous solid tire wastes in the north ofWest Bank. The disposable process is an environmentally friendly process and it converts tires intouseful products, which could reduce the fuel crisis in Palestine. The gravimetric analysis of tire wastepyrolysis products from the pyrolysis plant working at the optimum conditions is: tire pyrolysisoil (TPO): 45%, pyrolysis carbon black (PCB): 35%, pyrolysis gas (Pyro-Gas): 10% and steel wire:10%. These results are depending on the tire type and size. It has been found that the producedpyrolysis oil has a High Heating Value (HHV), with a range of42−43(MJ/kg), which could make ituseful as a replacement for conventional liquid fuels. The main disadvantage of using the TPO asfuel is its strong acrid smell and its low flash point, as compared with the other conventional liquidfuels. The produced pyrolysis carbon black also has a High Heating Value (HHV) of about 29 (MJ/kg),which could also encourage its usage as a solid fuel. Carbon black could also be used as activatedcarbon, printers’ ink, etc. The pyrolysis gas (Pyro-Gas) obtained from waste tires mainly consist oflight hydrocarbons. The concentration of H2has a range of 30% to 40% in volume and it has a highcalorific value (approximately31MJ/m3), which can meet the process requirement of energy. On theother hand, it is necessary to clean gas before the burning process to remove H2S from Pyro-Gas, andhence, reduce the acid rain problem. However, for the current plant, some recommendations shouldbe followed for more comfortable operation and safer environment work conditions.
