“…The microwave-assisted pyrolysis of polystyrene using different microwave absorbents (Fe, Fe 3 O 4 , FeS 2 , and SiC) was explored at the pyrolysis temperature of 460 °C, microwave power of 650 W, and microwave absorbent load of 60 g. Table lists the product yields and oil HHVs. The oil yields were all relatively high (>90 wt %) due to the high purity of polystyrene (>95%) and precise regulation of reaction parameter (460 °C, 650 W, and 60 g microwave absorbent loads) based on the previous study . The highest oil yield (94.67 wt %) was obtained by using Fe 3 O 4 .…”

“…The presence of aromatic hydrocarbons is beneficial to the improvement of the energy densities of oils . The molecular lengths of aliphatic hydrocarbons are usually shorter than those of aromatic hydrocarbons (especially polycyclic aromatic hydrocarbons), and the existence of aliphatic hydrocarbons helps to improve the physical and chemical properties of oils, i.e., viscosity, density, flash point, higher heating value, etc. , …”

As recycling plastics through microwave-assisted pyrolysis becomes gradually popular, the selection of microwave absorbents is therefore of great importance because plastics generally have low microwave absorption capacities, and microwave absorbents are then required to improve the heating and pyrolysis processes. In this study, conversion of polystyrene plastic into aviation fuel through microwave-assisted pyrolysis as affected by iron-based microwave absorbents (Fe, Fe3O4, and FeS2) was studied and reported for the first time. The heating performance, product yields, oil higher heating values, and aviation oil compositions with different microwave absorbents, microwave powers, and microwave absorbent loads were detailed. The results showed that Fe3O4 exhibited the highest average heating rate of 119.23 °C/min, and Fe had good selectivity for cycloalkenes, while FeS2 had good selectivity for olefins. The highest oil yield (97.67 wt %) was obtained at a pyrolysis temperature of 460 °C, microwave power of 650 W, and Fe load of 90 g, and the oil compositions were mainly monocyclic aromatic hydrocarbons, polycyclic aromatic hydrocarbons, olefins, and cycloalkenes with abundant C8–C16 hydrocarbons of 52.041–77.880 area%. The results indicated that polystyrene can be well converted into aviation fuel through microwave-assisted pyrolysis by screening the iron-based microwave absorbents.

“…However, under mild circumstances, the raw organics having lesser yield might be hydrogenated to comply with the high energy density of jet fuels (such RJ‐5 and JP‐10). Fan et al., [121] investigated the generation of aviation oil by the pyrolysis of PS using microwaves. For the purpose of producing aviation oil, the yields and components of oils at various microwave absorbent loads (including 30, 45, 60, 75, and 90 g of SiC), microwave powers (including 450, 550, 650, 750, and 850 watts), and pyrolysis temperatures (including 340, 400, 460, 520, and 580 °C) were developed.…”

Chemical upcycling of waste plastics into high‐value‐added products is one of the most effective, cost‐efficient, and environmentally beneficial solutions. Many studies have been published over the past few years on the topic of recycling plastics into usable materials through a process called catalytic pyrolysis. There is a significant research gap that must be bridged in order to use catalytic pyrolysis of waste plastics to produce high‐value products. This review focuses on the enhanced catalytic pyrolysis of waste plastics to produce jet fuel, diesel oil, lubricants, aromatic compounds, syngas, and other gases. Moreover, the reaction mechanism, a brief and critical comparison of different catalytic pyrolysis studies, as well as the techno‐feasibility analysis of waste plastic pyrolysis and the proposed catalytic plastic pyrolysis setup for commercialization is also covered.

“…Microwave radiation interacts well with PS waste via the medium’s dielectric constant and generates a quick heating process. Microwave processing features contain challenging characteristics: (a) rapid heating, (b) reduced energy consumption, (c) poor thermal inertia, and (d) high conversion efficiency of power [ 118 ]. The reaction was made possible by adjusting the microwave, temperature, powder, microwave design, catalyst, and absorber.…”

The excessive amount of global plastic produced over the past century, together with poor waste management, has raised concerns about environmental sustainability. Plastic recycling has become a practical approach for diminishing plastic waste and maintaining sustainability among plastic waste management methods. Chemical and mechanical recycling are the typical approaches to recycling plastic waste, with a simple process, low cost, environmentally friendly process, and potential profitability. Several plastic materials, such as polypropylene, polystyrene, polyvinyl chloride, high-density polyethylene, low-density polyethylene, and polyurethanes, can be recycled with chemical and mechanical recycling approaches. Nevertheless, due to plastic waste’s varying physical and chemical properties, plastic waste separation becomes a challenge. Hence, a reliable and effective plastic waste separation technology is critical for increasing plastic waste’s value and recycling rate. Integrating recycling and plastic waste separation technologies would be an efficient method for reducing the accumulation of environmental contaminants produced by plastic waste, especially in industrial uses. This review addresses recent advances in plastic waste recycling technology, mainly with chemical recycling. The article also discusses the current recycling technology for various plastic materials.
