Abstract The efficient utilization of organic solid waste resources can help reducing the consumption conventional fossil fuels, mitigating environmental pollution, and achieving green sustainable development. Due to its dual nature being both a resource source it is crucial implement suitable recycling technologies throughout upgrading processes for plastics biomass, which are wastes with complex mixture components. pyrolysis hydropyrolysis were summarized biomass into high‐value chemicals, materials. To enhance reaction efficiency improve product selectivity, microwave‐assisted was introduced through energy supply especially aid catalysts microwave absorbers. This review provides detail summary from technical, applied, mechanistic perspectives. Based on recent technological advances, future directions development predicted.

Abstract Microwave‐assisted pyrolysis of PE to hydrogen and carbon material has great potential solve the problem waste induced white pollution provide a promising way produce energy. To increase yield, new microwave‐assisted procedure should be developed. In present study, facile double‐layer (DLMP) method is developed pyrolyze PE. Within this method, can converted hydrogen, multiwalled nanotubes with extremely high efficiency compared traditional methods. A yield 66.4 mmol g −1 achieved, which ≈93% upper limit theoretical generated from process. The mechanism during using DLMP also clarified in detail. paved for recycling plastic into high‐value‐added products.
