“…Given its ability to produce various high-value products, such as liquid oil, syngas, and char, the cost of pyrolysis of medical waste has been greatly reduced [ 17 ]. The liquid oil and syngas can be upgraded into fuels and chemical feedstock by chemical means [ 18 , 19 ]. Pyrolysis char can be used as fuel for power generation due to its high carbon content and calorific value [ 20 ].…”

Effective in-site treatment of medical waste has become a weak link in hospitals. Pyrolysis technology is a treatment method for medical waste that can enable rapid disposal in hospital settings and relieve environmental pressure, while also producing high-value products and reducing disposal costs. In this work, the effects of feedstock ratio and temperature on product yield and components of gauze (GA) and medical bottles (MB) co-pyrolysis have been investigated. The higher yield of solid products was obtained by co-pyrolysis of GA and MB at 400 ℃. With the addition of MB and an increase in temperature for the co-pyrolysis of GA and MB in a similar ratio, the pyrolysis oil and gas yields gradually increased. According to GC–MS analysis, co-feeding 75% MB to GA improved the alcohol content from 33.21% to a maximum yield of 59.8% at a pyrolysis temperature of 700 ℃. The content of aliphatic hydrocarbon reached 38.68% when the pyrolysis temperature and MB addition ratio were 700 °C and 75%, respectively. The GC data shows that the main gas components of co-pyrolysis of GA/MB were CH 4 and H 2 , while the pyrolysis of pure GA or MB resulted in CO or CO 2 . Additionally, the solid carbon products obtained have an excellent pore structure. This strategy can benefit medical waste control and resource utilization for the low-cost disposal of medical waste and the acquisition of high-value resource products. Graphical Abstract

“…8 Biomass pyrolysis technology is a process in which organic matter in biomass is converted into volatile gas and solid residue under anaerobic or low oxygen conditions by external heating to a certain temperature. 9 The volatile gas can be converted into liquid product, namely, bio-oil, while the noncondensable small molecule gas can be used to produce fuel gas. Bio-char one of the main products of biomass pyrolysis, which can be used for combustion or gasification, and also serves as a high-quality raw material for the production of activated carbon and other high valueadded materials.…”

In this study, co‐generation from rice straw based on pyrolysis and gasification was studied by experimental and modeling approaches. Pyrolysis experiment results show that improving pyrolysis temperature will benefit the yield of gas and bio‐oil, while reducing the yield of bio‐char. The BET (Brunauer, Emmett, and Teller) surface area of bio‐char reached a maximum of 143.26 m2/g when the temperature was increased to 550°C. For co‐generation in this study, an optimized pyrolysis temperature of 500°C was selected. With respect to gasification, air equivalence ratio (ER) largely influenced the syngas yield and composition. At ER = 0.25, the concentration of H2 and CO reached a maximum of 17.8 wt% and 16.2 wt%. Based on the experimental results, an Aspen Plus model was built to evaluate the mass and energy balance during co‐generation. Furthermore, a life cycle assessment method was used to evaluate the greenhouse gas emission during co‐generation process initialed from rice straw planting. Results show that the greenhouse gas emission intensities of the two co‐generation systems were 2.92 and 3.51 g CO2/MJ respectively, which were much lower than traditional fossil fuels.

“…Different biomass feedstocks often exhibit distinct pyrolysis behavior characteristics under different pyrolysis conditions, and these pyrolysis behavior characteristics are key indicators for evaluating the conversion of biomass into usable energy. [3][4][5] Although research on the thermal behavior of biomass has been ongoing, there is still no consensus on the typical biomass pyrolysis process, gaseous product release patterns, kinetic parameters, thermodynamic properties, and pyrolysis mechanism functions. Even for the same type of biomass, differences in origin and growth stage can impact the pyrolysis process, mainly due to the varying relative contents of cellulose, hemicellulose, and lignin in biomass.…”

To investigate the effective utilization of agricultural and forestry wastes for mitigating the shortage of primary energy and environmental pollution, the pyrolysis behavior of corn straw (CS), wheat straw (WS), and poplar sawdust (PS) was studied using thermogravimetric–Fourier transform infrared (TG‐FTIR) analysis. The activation energies and pyrolysis mechanism functions of different biomass types were calculated. The results showed that the functional group structures of the gaseous products generated from the pyrolysis of different biomass types were similar, mainly including OH, aliphatic CH, CO, aromatic ring skeleton, aromatic CH, and CO groups. These functional group structures mainly existed in oxygen‐containing compounds such as phenols, ketones, aldehydes, acids, esters, alcohols, and ethers. The pyrolysis process of agricultural and forestry wastes exhibited certain differences, with the PS undergoing thermal decomposition more easily, while the thermal decomposition mechanism functions of the two agricultural wastes (CS and WS) were similar. PS had a later initial release time for volatile matter, and the oxygen compounds produced by its pyrolysis were the highest, followed by WS and CS.
