“…Plastic polymers and plants (such as cellulose and chitin) share chemical properties and polymer structures, including partially crystalline regions, surface hydrophobicity and backbones linked by hydrolysable bonds ( Daly et al, 2021 ). The carbohydrate binding modules (CBM), which includes the chitin-binding domain (ChBD), is a type of noncatalytic domain found extensively in glycoside hydrolases facilitating their adsorption to the insoluble substrate ( Boraston et al, 2004 ).…”

Polyethylene terephthalate (PET) is a mass-produced petroleum-based non-biodegradable plastic that contributes to the global plastic pollution. Recently, biocatalytic degradation has emerged as a viable recycling approach for PET waste, especially with thermophilic polyester hydrolases such as a cutinase (LCC) isolated from a leaf-branch compost metagenome and its variants. To improve the enzymatic PET hydrolysis performance, we fused a chitin-binding domain (ChBD) from Chitinolyticbacter meiyuanensis SYBC-H1 to the C-terminus of the previously reported LCCICCG variant, demonstrating higher adsorption to PET substrates and, as a result, improved degradation performance by up to 19.6% compared to with its precursor enzyme without the binding module. For compare hydrolysis with different binding module, the catalytic activity of LCCICCG-ChBD, LCCICCG-CBM, LCCICCG-PBM and LCCICCG-HFB4 were further investigated with PET substrates of various crystallinity and it showed measurable activity on high crystalline PET with 40% crystallinity. These results indicated that fusing a polymer-binding module to LCCICCG is a promising method stimulating the enzymatic hydrolysis of PET.

“…However, pathway I has the advantages of environmental protection because it uses UV and enzymes. 2 The results of degradation of pathway II were better, as they effectively reduced the molecular weight of the LDPE. However, a large number of ester bonds persisted in the product ( CPBA PE-M6) and there was the possibility of further degradation.…”

“…Compared with the degradation of UV PE by Lac 6 and Lcp, 9 pathways I, II, and III showed good efficiency of degradation. In addition, the products of degradation of the three pathways were all fatty acids, and could be further degraded, such as through the use of oxidoreductase to produce CO 2 11,34,35 and zeolite to catalyze the production of CO. 36 This can help completely degrade PE 2 and avoid the threat posed by microplastics to the environment. 37…”

“…1 The degradation of polyethylene waste has long been a problem. 2 Compared with physical or chemical methods, techniques for the biodegradation of polyethylene have the advantages of low energy consumption and environmental protection. 2 Owing to the higher bond energy of its carbon-carbon single bonds (330-370 kJ mol −1 ), 3 polyethylene requires functionalization before plastic-degrading enzymes can be used to catalyze its degradation reaction.…”

Lignocellulosic biomass is the world largest renewable resource used as a raw material to produce high‐value‐added chemicals, such as biofuels and other biomaterials. However, the complex chemical structures of its main constituents, named cellulose, hemicelluloses, and lignin, pose a challenge to the breakdown of these biopolymers into smaller units. In this scenario, sustainable methods for the depolymerization of lignocellulosic biomass aim to chemically break these macromolecules into simple monomers and dimers, while minimizing the use of hazardous chemicals and energy‐intensive processes. Different depolymerization strategies have been proposed, including enzymatic, electrochemical, acid‐catalyzed, and solvent‐based methods. Nevertheless, the development and improvement of sustainable approaches toward depolymerization technologies is still ongoing, and there is still room for further research to optimize the efficiency, cost‐effectiveness, and scalability of the processes. While the successful depolymerization of biomass may significantly contribute to the transition to a more sustainable and environmentally friendly economy, this article outlines the most recent developments focusing on the particularities of these processes, including biological, electrochemical, thermal, and chemical methods.
