Abstract: Since increasing amount of waste plastics is becoming a severe global environmental threat, recovering waste plastics and converting it to usable resources has attracted a lot of attention in the world. This review has summarized the current R&D and commercialization status for various technologies including thermal cracking, catalytic cracking which convert waste plastics to fuel around the world. After thorough comparison, we believe that catalytic cracking has the best potential to become the future commercial technology for converting waste plastics to fuel efficiently, environment-friendly, and without secondly pollution. It also describes the impact of temperature, residence time, waste plastics composition, catalyst, and reactor configuration on cracking reactions. Suggestions and recommendations are provided regarding how to improve technology commercialization, especially dechlorination of mixed waste plastics, increasing the yield of liquid products and improving the stability of oil products.

Key words: waste treatment, fuel, catalyst, catalytic cracking, reactors, industrialization
