Carbon dioxide (CO2) mitigation is a common goal for the manufacturing industries around the world. As the energy efficiencies of domestic petrochemical facilities reached the top level in the world, the use of recovered feedstock from renewable sources or plastic wastes is the most plausible way to reduce the life cycle CO2 emissions of products. Pyrolysis of waste plastics is commercially feasible technology owing to the potential use of pyrolysis oil as a steam cracker feedstock to produce the chemically recycled polymers. Here, the global trends of supplies and demands for the recovered feedstock and the pyrolysis technologies for plastic wastes were discussed. Also, the practical limitations of current pyrolysis technologies and requirements of pyrolysis oil and naphtha as a steam cracker feedstock were also studied. Finally, the directions for the development of next-generation catalytic pyrolysis processes were proposed to achieve high reliability and economic feasibility. |
