Pyrolysis plant is widely used in waste recycling, mainly for waste tires, waste plastics and oil sludge. Pyrolysis is a process in which molecules are broken at an appropriate temperature to generate valuable end products under anaerobic or oxygen-deficient conditions, and the products are mainly fuel oil, carbon black, steel wire and syngas. End products are differnt depends on different waste. Pyrolysis plant recycles waste tires, plastics and oil sludge in the environmental-protective way, reducing the amount of global waste and helping to solve global pollution problems.
