Solving Ecological Problem of Pyrolysis Carbon Black (PCB)

Tire waste is one of the most important problems of environmental solid waste in the world. Since, the waste tire cannot be treated in a landfill nor burned, because it releases serious toxic gases. So, several methods have been proposed for waste tire treatment. Among these methods waste, tire pyrolysis is considered the most favorable. Pyrolysis is a process of converting waste tires into gases, fuel oil, steel, and a byproduct, which is pyrolyzed carbon black (PCB). However, gas and oil can be sold out in the local market as well as steel, while PCB that contains 30-35 wt% of the waste tire product becomes another solid waste problem. In this experimental investigation, an attempt was made to employing PCB in concrete that is used in building. Accordingly, a PCB sample will obtain from a local pyrolyzed waste tire plant; this will use as received without any chemical purification. The compression strength will be tested to find the effect of adding PCB to concrete.
