Of all the existing materials,plastics are no doubt among the most versatile ones.However,the extreme increases in plastic production as well as the difficulty of the material for degradation have led to a huge number of plastic wastes.Their recycling rate after disposal is less than 10％,resulting in a series of seri-ous environmental and ecological problems as well as a significant waste of resources.Current recycling methods generally suffer from large energy consumption,the low utilization rate of recycled products with low added value,and produce other waste during the process.Here,we summarized recently-developed chemical recycling ways on commodity plastics,especially new catalytic paths in production of fuels,high-valued chemicals and advanced materials from a single virgin or a mixture of plastic waste,which have emerged as promising ways to valorize waste plastics more economically and environmen-tally friendly.The new catalyst design criteria as well as innovative catalytic paths and technologies for plastic upcycling are highlighted.Beyond energy recovery by incineration,these approaches demonstrate how waste plastics can be a viable feedstock for energy use with the generation of clean H2,high-quality liquid fuels and materials for energy storage,and help inspiring more catalytic process on plastic upcy-cling to overcome the economical hurdle and building a circular plastic economy.
