“…Potnuri [ 33 ] blended an adequate amount of KOH into wood chips, and roasting experiments were carried out at 125–175 °C. The results showed that the addition of KOH effectively increased the tar yield (57.1–59.6 wt%) and char yield (27.3–29 wt%) and that KOH acted as a regulator in the roasting process.…”

In a study on the roasting of wood chips, Valizadeh [34] found that acids and phenols dominated the bio-oil at a roasting temperature of 300 • C and that increasing the roasting temperature decreased the yield of phenols in the bio-oil.…”

Roasting is an important step in the pretreatment of biomass upgrading. Roasting can improve the fuel quality of biomass, reduce the O/C and H/C ratios in the biomass, and provide the biomass with a fuel quality comparable to that of lignite. Therefore, studying the structure and component evolution laws during biomass roasting treatment is important for the rational and efficient utilization of biomass. When the roasting temperature is 200–300 °C, the cellulose and hemicellulose in the biomass undergo a depolymerization reaction, releasing many monocyclic aromatic hydrocarbons with high reactivity. The proportion of monocyclic aromatic hydrocarbons in biomass roasting products can be effectively regulated by controlling the reaction temperature, residence time, catalyst, baking atmosphere, and other factors in the biomass roasting process. This paper focuses on the dissociation law of organic components in the pretreatment process of biomass roasting.

“…Table 3 lists the proportion of residues produced. In the study of Potnuri et al [111], the amount of coke produced increases with the increase in KOH, and it is thought that KOH accelerates the co-pyrolysis rate of plastics and biomass to produce coke. The research on the used frying oil (UFO) and plastic (PW) co-pyrolysis by Mahari et al [68] found that at a high UFO/PW ratio, the hydrogen supply of PW was insufficient, which reduced the depolymerization and dehydrogenation of polymer, increased carbonization, and led to the formation of coke.…”

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.

Biochar, a carbon‐rich material derived from organic biomass under low‐O2 conditions, has gained importance due to its role in mitigating climate change by sequestering carbon. It can be used as an alternative energy source and has applications in nutrient cycling, improving soil properties, and removing heavy metals and organic pollutants, thus contributing to sustainable agriculture and environmental remediation. In the face of alarming climate change, rising energy demand, and increasing pollution, the integration of biochar production into biorefineries is an important strategy to promote a sustainable and circular economy. Adopting a holistic approach to biomass utilization by developing strategies to maximize biochar production along with the production of other value‐added products while improving its quality can increase biorefineries' overall sustainability and efficiency. Fine‐tuning the biorefinery process from feedstock selection to co‐production, optimizing pyrolysis conditions, and integrating it with other technologies can help to achieve this goal while generating zero waste and diversified revenues. With the biochar market growing exponentially, further research into the long‐term impact of biochar on carbon sequestration and its application in the environment is the next step.
