“…They also found that BPA will decompose into phenol and iso-allylphenol above 220 °C, which will affect the purity of the product polyols. In the study of Suriapparao Group [52], the synergistic effect of co-pyrolysis of algae (FA) with PP, PE, and EPS was investigated. In the co-pyrolysis combination of FA+PP and FA+PE, the pyrolytic volatile oxygen compounds of PA are easy to react with the volatile hydrocarbons of polymer pyrolysis, resulting in an increased gas yield in the product, showing a positive synergistic effect of the gas.…”

“…The contents of aliphatic hydrocarbons and aromatic hydrocarbons in bamboo pyrolysis products are extremely low, but the hydrocarbon content in the products is significantly increased, because PP can be used as a hydrogen donor to provide hydrogen for the dehydration and dehydrogenation of bamboo pyrolysis steam on the catalyst, reducing the formation of coke; thus, forming a synergistic effect with bamboo 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.

“…Moreover, the use of NiFe 2 O 4 generated well-structured carbon nanotubes (CNTs) of relative purity than other catalysts like Al 2 O 3 and Fe 2 O 3 . On the other hand, using a ZSM-5 catalyst promoted the excessive cracking of algae biomass during the catalytic microwave-assisted co-pyrolysis with EPS or other plastics, leading to higher gas and coke residues [40]. The bio-oil produced predominantly comprised phenolic compounds attributed to algae and monoaromatic hydrocarbon derivatives attributed to EPS.…”

Several environmental and techno-economic assessments highlighted the advantage of placing polystyrene-based materials in a circular loop, from production to waste generation to product refabrication, either following the mechanical or thermochemical routes. This review provides an assortment of promising approaches to solving the dilemma of polystyrene waste. With a focus on upcycling technologies available in the last five years, the review first gives an overview of polystyrene, its chemistry, types, forms, and varied applications. This work presents all the stages that involve polystyrene’s cycle of life and the properties that make this product, in mixtures with other polymers, command a demand on the market. The features and mechanical performance of the studied materials with their associated images give an idea of the influence of recycling on the structure. Notably, technological assessments of elucidated approaches are also provided. No single approach can be mentioned as effective per se; hybrid technologies appear to possess the highest potential. Finally, this review correlates the amenability of these polystyrene upcycling methodologies to frontier technologies relating to 3D printing, human space habitation, flow chemistry, vertical farming, and green hydrogen, which may be less intuitive to many.

“…Using microwave-assisted technology, the BET surface area of biochar was increased by 75.97 m 2 /g as compared to conventional heating [36]. Another study reported even higher char's surface area using ZSM-5 catalysts, ranging from 118-125 m 2 /g while obtaining considerably high bio-oil content as final product [38]. The CAs: Carboxylic acids; SCs: Saccharides; HCs: Hydrocarbons; HHV: Higher heating value; HDPE: High density polyethylene.…”

Catalytic reactions in producing biofuels often face issues such as low product yield, low selectivity to preferred products and serious environmental issues which leads to the exploration of green technologies. Microwave technology is one of the green technologies that is widely applied in the field such as medical, food, signal processing or navigation, and has been reviewed for its potential in the catalytic reactions for biofuel production. With the application of microwave technology, its unique heating mechanism consists of magnetic field energy and electric field energy that enables the selective heating of materials, allowing rapid reaction and enhancement of catalytic performance of catalysts. In general, this review has discussed on the fundamentals and mechanisms of microwave technology with an in-depth discussion on the application of microwave-absorbing catalysts for biofuel production, especially in ammonia synthesis, bio-oil and 5-HMF production as well as methanation. Lastly, the challenges and future prospect of microwave-absorbing catalysts are included as well.
