“…Traditional methods to address plastic pollution include designing degradable or recyclable plastics and developing recycling technologies. Currently, the primary methods for handling discarded plastics include landfilling, incineration, mechanical recycling, and chemical recycling. − However, plastic landfilling occupies valuable land resources and poses a significant risk of ground and water contamination as a result of toxic species. ,,,, The incineration involves directly burning plastics for heat generation, but it usually produces toxic gases, such as polycyclic aromatic hydrocarbons, carbon monoxide, dichlorodiphenyltrichloroethane, and dioxins, which further cause atmospheric pollution. − …”

Chemical upgrading of waste plastics is currently one of the most important methods for addressing plastic pollution. In comparison to the current methods of incineration or landfill, chemical upgrading enables the utilization of carbon and hydrogen elements in waste plastics as resources. This process strongly relies on efficient catalysts and reaction systems. Through catalyst design, waste plastics can be converted into fuels or chemicals under the optimized reaction conditions, extending their life cycles. In this review, we systematically discuss various chemical conversion methods for polyolefin waste plastics, which account for a large proportion of waste plastics. We further explore the remaining challenges and future development trends in this field, including improving product value through product engineering and shifting research perspectives to exploring the tolerance of catalysts toward impurities in practical waste plastic waste rather than using pure plastic feedstock.

Sustainability, chemical safety, and circular economy represent holistic frameworks that support chemical synthesis, design, manufacturing, use, reuse, recycling, and disposal to create a closed-loop economic production system. Also, these frameworks target minimizing waste generation, energy consumption, and fresh raw material needs, maximizing resource efficiency, and economic, social, and environmental benefits. Therefore, designing a safer economy for chemicals includes the contribution of all chemical life cycle stages, starting from utilizing safer renewable feedstocks, developing safer chemical products, implementing sustainable chemical manufacturing systems, effective regulatory foundations, and non-destructive end-of-life management systems.
