“…Bernardo et al [ 59 ] found that biochar obtained after the co-pyrolysis of pine, used tires, and plastic wastes at 420 °C had more mesopores and oxygen functional groups and exhibited a high adsorption capacity for Pb 2+ . Silori et al [ 60 ] used biochar by the co-pyrolysis of sawdust and plastic wastes to adsorb antibiotics in wastewater, and the adsorption capacity of biochar obtained by co-pyrolysis was lower than that obtained by individual pyrolysis of biomass.…”

The recycling of plastic packaging wastes helps to alleviate the problems of white pollution and resource shortage. It is very necessary to develop high-value conversion technologies for plastic packaging wastes. To our knowledge, carbon materials with excellent properties have been widely used in energy storage, adsorption, water treatment, aerospace and functional packaging, and so on. Waste plastic packaging and biomass materials are excellent precursor materials of carbon materials due to their rich sources and high carbon content. Thus, the conversion from waste plastic packaging and biomass materials to carbon materials attracts much attention. However, closely related reviews are lacking up to now. In this work, the pyrolysis routes of the pyrolysis of plastic packaging wastes and biomass materials for conversion to high-value carbons and the influence factors were analyzed. Additionally, the applications of these obtained carbons were summarized. Furthermore, the limitations of the current pyrolysis technology are put forward and the research prospects are forecasted. Therefore, this review can provide a useful reference and guide for the research on the pyrolysis of plastic packaging wastes and biomass materials and the conversion to high-value carbon.

“…Studies have shown that biochar (SB) produced by pyrolysis of sawdust can adsorb ciprofloxacin (CFX) and sulfamethoxazole (SMX), with maximum adsorption capacities of 3.54 and 3.40 mg/g, respectively (initial concentration 20 mg/L, removal rates above 85%). Kinetic fitting indicated that the adsorption of both compounds follows pseudo-second-order kinetic behavior ( Silori et al, 2023 ). After capturing CHCs molecules, surface active substances [such as carboxyl groups -COOH, hydroxyl groups -OH, metal atoms ( Cheng et al, 2024 ), non-metallic active substances N and S, etc.…”

Dehalogenating bacteria are still deficient when targeted to deal with chlorinated hydrocarbons (CHCs) contamination: e.g., slow metabolic rates, limited substrate range, formation of toxic intermediates. To enhance its dechlorination capacity, biochar and its composites with appropriate surface activity and biocompatibility are selected for coupled dechlorination. Because of its special surface physical and chemical properties, it promotes biofilm formation by dehalogenating bacteria on its surface and improves the living environment for dehalogenating bacteria. Next, biochar and its composites provide active sites for the removal of CHCs through adsorption, activation and catalysis. These sites can be specific metal centers, functional groups or structural defects. Under microbial mediation, these sites can undergo activation and catalytic cycles, thereby increasing dechlorination efficiency. However, there is a lack of systematic understanding of the mechanisms of dechlorination in biogenic and abiogenic systems based on biochar. Therefore, this article comprehensively summarizes the recent research progress of biochar and its composites as a “Taiwan balm” for the degradation of CHCs in terms of adsorption, catalysis, improvement of microbial community structure and promotion of degradation and metabolism of CHCs. The removal efficiency, influencing factors and reaction mechanism of the degraded CHCs were also discussed. The following conclusions were drawn, in the pure biochar system, the CHCs are fixed to its surface by adsorption through chemical bonds on its surface; the biochar composite material relies on persistent free radicals and electron shuttle mechanisms to react with CHCs, disrupting their molecular structure and reducing them; biochar-coupled microorganisms reduce CHCs primarily by forming an “electron shuttle bridge” between biological and non-biological organisms. Finally, the experimental directions to be carried out in the future are suggested to explore the optimal solution to improve the treatment efficiency of CHCs in water.
