Polypropylene (PP) is currently the second largest general-purpose plastic. With the development of construction, automobile, household appliances and packaging industries, waste PP has become one of the waste polymer materials with large output in recent years. At present, the main ways to deal with waste PP are incineration for energy supply, catalytic cracking for fuel preparation, direct utilization and recycling. Considering the technical feasibility, cost, energy consumption, environmental protection and other factors in the process of waste PP treatment, recycling is the most commonly used, effective and most advocated way to deal with waste PP.
