“…Therefore, it was speculated that biomass was covered by molten plastics that blocked porous structure of biochar and inhibited the release of volatiles, thus increasing the biochar yield. Similarly, Stančin et al found that adding 25% of PU to biomass could increase the biochar yield by 27%.…”

“…87 However, it does not mean that copyrolysis of nitrogenous plastics and biomass can be used to produce liquid fuel, because liquid products mainly comprise aniline that contains excessive nitrogen and does not meet the usage standards for standard fuel. 28 Pyrolysis behavior of nitrogenous plastics resembles that of biomass. There are three stages of weight loss and a broad weight loss peak.…”

“…Considering the bio-oil quality, adding nitrogenous plastics to biomass pyrolysis reduces the content of oxygencontaining compounds. Stancǐn et al 28 investigated the effect of feedstock proportion on the bio-oil quality and found that a small amount of polyurethane (PU) could completely remove aldehydes and sugars and significantly reduce ketones and acids. As the PU proportion increased, the phenolic yield decreased by 97% at most.…”

“…For example, when the metal content in biochar increases due to copyrolysis with sludge, it is necessary to consider whether the total or leachable content of heavy metals in biochar exceeds the corresponding standards . Bio-oil can be difficult to use as fuel due to the introduction of additional nitrogen or sulfur elements during copyrolysis . However, on the whole, copyrolysis plays a positive role in most cases.…”

Pyrolysis is one of the substantial thermal conversion technologies for high-value reutilization of biomass and organic solid waste (OSW). Adding some typical OSWs to biomass pyrolysis can achieve directional regulation of target products that are considered potential alternatives to fossil energy. Understanding copyrolysis behaviors is vital for the optimizing pyrolysis process to minimize environmental pollution and efficiently utilize biomass and OSW. However, there is no overall review on the copyrolysis of biomass and various OSWs. This paper reviews and discusses recent advances in the copyrolysis mechanism, thermal−chemical processes of some typical OSWs and biomass, and effects of chemical compositions of raw materials and pyrolysis parameters on thermal−chemical conversion behaviors, synergistic effect, and copyrolysis product characteristics. Recent reports show that the synergistic effect in copyrolysis effectively improves the quality of bio-oil and biochar. Moreover, adding OSW to biomass pyrolysis can promote the secondary reaction of pyrolysis intermediates. The reaction mechanism and relative numerical simulation work of copyrolysis are summarized. Finally, the current challenges to energy-and environment-oriented conversion of biomass and OSW are discussed, and perspectives for further developing the copyrolysis process are highlighted. This paper provides valuable information for optimizing sustainable copyrolysis processes of OSW and biomass and improving the efficiency and selectivity of recycled OSW.
