“…Suriapparao et al [65] conducted the MAP of rice husk and plastic, and reported that the highest efficiency of the microwave co-pyrolysis process could reach 68%. In the MAP study of PP by Kamireddi et al [114], the microwave conversion efficiency calculated by experiments reached 84.7%, and the pyrolysis oil with a calorific value of 45.4 MJ/kg was obtained. In the study of MAP of HDPE, Zhou et al [99] calculated the energy balance and found that the energy efficiency of pyrolysis of HDPE can reach 89.6%, better than that of traditional pyrolysis.…”

The exhaustion of fossil energy and the severe pollution induced by using plastics has forced people to embark on the road to sustainable development. The high value of the recycling of plastics has become an important part of energy conservation. Microwave treatment, owning specific interactions between the electric field and the molecules of treated materials, presents potential advantages in the application of plastic pyrolysis. Therefore, the research status of the microwave-assisted pyrolysis (MAP) of plastics to produce high-value-added liquid oil, gas, and solid carbon was reviewed in this paper. The effects of plastic properties, microwave treatment parameters, microwave absorbers, co-pyrolysis, catalysts, and reactor devices on the process and the products were analyzed. It is essential to optimize the experimental design by studying microwave-assisted co-pyrolysis technology and the application of catalysts, understanding the mechanism of co-pyrolysis to improve product selectivity. At the same time, the continuous MAP device for large-scale plastics treatment still needs to be developed. In addition, developing a large-scale simulation computing research platform for screening catalysts, optimizing processes, and commercial production is required to make the process more efficient.

“…Kamireddi et al performed 13 microwave-assisted catalytic co-pyrolysis experiments of PP and polystyrene (PS) mixtures and used machine learning to estimate the impact of the PP and PS quantity on the oil yield, gas yield and pyrolysis time. 22 Wu et al conducted injection molding of isotactic polypropylene into 27 specimens, collecting data on the polymorphic structure and mechanical properties to develop four machine learning models. 23 The XGB model has the highest prediction accuracy for polymorphic form contents and mechanical properties based on the various processing parameters.…”
