Photocatalysis toward Microplastics Conversion: A Critical Review

ACS Catalysis, Journal Year: 2024, Volume and Issue: 14(11), P. 8694 - 8719

Published: May 20, 2024

Microplastics (MPs, particle size < 5 mm) have become increasingly ubiquitous on Earth due to the cleavage and degradation of heavy use plastics. MPs recently been reported be detected in human blood, alveoli, breast milk, embryos, other organs, raising concerns about their environmental risks. Photocatalysis has identified as a potential means for conversion, which utilizes solar energy stimulate semiconductor photocatalyst. However, study photocatalytic conversion is still incubation period. This review overviews current state-of-the-art technologies conversion. Then, fundamental principles, challenges, analytical techniques, evaluation indexes reforming are highlighted. We systematically summarized recent advances key factors influencing performance. Finally, we propose some perspectives developing efficient systems MPs. will provide guideline applying technology MPs, significantly contribute this emerging research field.

Radical innovation breakthroughs of biodegradation of plastics by insects: history, present and future perspectives

Frontiers of Environmental Science & Engineering, Journal Year: 2024, Volume and Issue: 18(6)

Published: April 30, 2024

Abstract Insects damaging and penetrating plastic packaged materials has been reported since the 1950s. Radical innovation breakthroughs of biodegradation have initiated discovery plastics by Tenebrio molitor larvae in 2015 followed Galleria mellonella 2017. Here we review updated studies on insect-mediated plastics. Plastic insect larvae, mainly some species darkling beetles (Tenebrionidae) pyralid moths (Pyralidae) is currently a highly active potentially transformative area research. Over past eight years, publications increased explosively, including discoveries ability different to biodegrade plastics, performance, contribution host microbiomes, impacts polymer types their physic-chemical properties, responsible enzymes secreted gut microbes. To date, almost all major polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), terephthalate (PET), polyurethane (PUR), polystyrene (PS) can be biodegraded T. ten other representing Tenebrionidae Pyralidae families.

Recent progress in biodegradation of microplastics by Aspergillus sp. in aquatic environments

Colloids and Interface Science Communications, Journal Year: 2023, Volume and Issue: 57, P. 100754 - 100754

Published: Nov. 1, 2023

The potential of Aspergillus sp. for plastic biodegradation is a promising approach environmentally friendly waste management. Various research studies have been conducted to optimize conditions that enhance the plastics and understand genetic basis species. By performing this investigation, we discussed role various species in decomposition polymers. Most grow within pH range 4 6. 37.5% showed grows optimally at 30 °C. Scanning electron microscopy (SEM) Fourier transform infrared (FTIR) tests were used 34.61% 32.69% different studies, respectively. It has observed fungi can biodegrade polymers more effectively size 20–100 μm. (34.21%) focused on 21 days. highest percentage (44%) low-density polyethylene (LDPE) by dominant sp., including A. niger, flavus, oryzae, play significant microplastics. Enzymes such as laccase, esterase, peroxidase, lipase, urease crucial roles degradation plastics. Laccase utilizes oxygen generate reactive species, breaking polymer chains. Esterase cleaves into fragments, while peroxidase generates radicals degradation. Lipases also contribute specific substrates. In general, it be said fungal successful degrading
