Photocatalytic strategy to mitigate microplastic pollution in aquatic environments: Promising catalysts, efficiencies, mechanisms, and ecological risks

Microbial Enzyme Biotechnology to Reach Plastic Waste Circularity: Current Status, Problems and Perspectives

“…Moreover, as most biodegradation processes have only been conducted at laboratory scale [ 176 , 178 ], without biochemical information on the kinetics of the involved reactions, with scarce data on degradation products, and often observing that mainly additives were cleaved [ 197 ], a fully bio-based depolymerization of non-polyester petroleum-based plastics is predicted not to be economically and environmentally competitive with traditional approaches within a 10-year time frame. Instead, it is necessary to look at new approaches of tertiary recycling [ 34 , 198 , 199 ] and to use them in combination with microbial enzymes to convert degradation products into high-added-value chemicals [ 188 , 200 , 201 ].…”

Harnessing photosynthetic microorganisms for enhanced bioremediation of microplastics: A comprehensive review

“…The environmental factors generate abrasion, shear (compressive, tensile, and flexural), and torsional impact [ [38] , [39] , [40] , [41] ]. Several manuscripts have reviewed the biotic and abiotic treatment of MPs [ [41] , [42] , [43] , [44] , [45] , [46] , [47] ]. Chen et al.…”

Metal Oxides‐Based Nano/Microstructures for Photodegradation of Microplastics

“…[16] Microplastics are often more difficult to photocatalytically degrade than other organic substrates including dyes, medications, and other organic substances with low molecular weights. [17] Lower photocatalytic degradability is caused due to low solubility in water, complicated chemistry, low biodegradability, and low adsorption ability of the microplastic on the surface of the photocatalyst. Accurately determining the photodegradation process is a challenge in the degradation of microplastics since many mechanisms are observed to follow random routes as a result of the numerous opportunities for bond breakage, recombination, or the addition and removal of atoms.…”

“…The degradation processes (biodegradation, photodegradation, chemical, and thermal degradation) for microplastics, the influence of intrinsic properties, environmental factors during the degradation process, and the environmental impact of the degradation products of microplastics were all encased by Liu et al [14] in their review. He et al [17] reviewed the photocatalytic techniques for reducing microplastic pollution, covering the most recent developments related to key parameters for assessing photodegradation, promising photocatalysts and key mechanisms, potential synergistic reactions, modification of photocatalysts through doping metal, decorating functional group, etc. The use of self-propelling micromotors for the photocatalytic and photo-Fenton chemistry treatment of microplastics was briefly discussed by Hermanová and Pumera.…”
