Upcycling of plastic wastes for hydrogen production: Advances and perspectives

Renewable and Sustainable Energy Reviews, Journal Year: 2024, Volume and Issue: 195, P. 114333 - 114333

Published: Feb. 27, 2024

The abundant plastic wastes become an imperative global issue, and how to handle these organic gains growing scientific industrial interest. Recently, converting into hydrogen fuel has been investigated, the "waste-to-value" practice accelerates circular economy. To accelerate development of plastic-to-hydrogen conversion, in this review, recent advances conversion via thermochemical, photocatalytic, electrocatalytic routes are analyzed. All thermo-, photo-, electrochemical processes can transform different hydrogen, production efficiency depends heavily on selected techniques, operating parameters, applied catalysts. application rational-designed catalysts promote selective from feedstocks. Further studies process optimization, cost-effective catalyst design, mechanism investigation needed.

Toxicological review of micro- and nano-plastics in aquatic environments: Risks to ecosystems, food web dynamics and human health

Ecotoxicology and Environmental Safety, Journal Year: 2024, Volume and Issue: 278, P. 116426 - 116426

Published: May 8, 2024

The increase of micro- and nano-plastics (MNPs) in aquatic environments has become a significant concern due to their potential toxicological effects on ecosystems, food web dynamics, human health. These plastic particles emerge from range sources, such as the breakdown larger waste, consumer products, industrial outputs. This review provides detailed report transmission dangers MNPs environmental behavior, interactions within webs, emphasizing toxic impact marine life. It explores relationship between particle size toxicity, distribution different tissues, process trophic transfer through web. MNPs, once consumed, can be found various organs, including digestive system, gills, liver. Their consumption by lower level organisms facilitates progression up chain, potentially leading bioaccumulation biomagnification, thereby posing substantial risks health, reproduction, behavior species. work also how persistence bioaccumulation, pose biodiversity disrupt relationships. addresses implications for particularly contaminated seafood, highlighting direct indirect pathways which humans are exposed these pollutants. Furthermore, highlights recommendations future research directions, integration ecological, toxicological, health studies inform risk assessments develop mitigation strategies address global challenge pollution environments.

Terrestrial and Aquatic Plastisphere: Formation, Characteristics, and Influencing Factors

Sustainability, Journal Year: 2024, Volume and Issue: 16(5), P. 2163 - 2163

Published: March 5, 2024

The increasing number of plastic particles in the environment gives rise to a unique ecological niche called plastisphere, which is characterized by dynamic assemblage microorganisms comprising autotrophs, heterotrophs, predators, and pathogens. This paper reviews formation, characteristics, factors influencing terrestrial aquatic plastisphere. plastisphere forms when hitchhiking microorganisms, often bacteria, adhere surfaces alter surface properties for subsequent colonization increasingly tightly clinging microorganisms. not as mobile defined characteristics soil anchoring it. on are dominant surroundings, particularly those phyla Proteobacteria, Actinobacteria, Bacteroidota, Firmicutes, Chloroflexi, Acidobacteria, Cyanobacteria, Ascomycota, Basidiomycota, Chytridiomycota, Ciliophora, Ochrophyta, Chlorophyta. However, compositions microbial species different vary widely they change with time, properties, biotic abiotic environmental factors. Temporal changes due succession. Plastic type, size, color, degree aging, chemical leaching, also affect composition Biotic ambient interspecies interactions, together ones, including pH, temperature, nutrient availability, salinity, light, significantly shape review provides insight into biodiversity its roles spreading pathogens degrading plastics.

Carbon-based adsorbents for micro/nano-plastics removal: current advances and perspectives

Water Emerging Contaminants & Nanoplastics, Journal Year: 2024, Volume and Issue: 3(2)

Published: April 1, 2024

Carbon-based adsorbents, such as graphene, graphene oxide (GO), activated carbon/biochar (AC/BC), carbon nanotubes (CNTs), metal-modified carbon, and fly ash, are garnering increasing attention due to their exceptional structural properties, enabling potential effectiveness in removing microplastics nano-plastics (MPs/NPs) from aqueous solutions. A key attribute contributing the efficacy of these adsorbents addressing MPs/NPs is flexibly tunable surface properties. To advance applicability functionalized context removal, it necessary highlight interactions with environments. The review commences by outlining main adsorption mechanisms. Subsequently, behavior different types on carbon-based analyzed how factors influence performance examined. Finally, concludes offering insights into prospective avenues for future research concerning functional removal.

Removal of microplastic particles during municipal wastewater treatment: A current review

Desalination and Water Treatment, Journal Year: 2024, Volume and Issue: 317, P. 100006 - 100006

Published: Jan. 1, 2024

Wastewater treatment plants (WWTPs) are considered the main point source of microplastics (MPs) discharged into water bodies. The article discusses types and number MPs present in wastewater effectiveness their removal at municipal WWTP. use different methodologies for determining makes it difficult to compare results obtained studies authors. Limitations various sampling, preparation final identification techniques MPs, that may lead over or underestimating wastewater, were indicated. Although efficiency on WWPP is reaching 98% more with advanced treatment, large WWTP could as much 1010 MPs/day. These values often do not take account particles smaller than 1 µm (nanoplastics), which effluent can be significant. degradation products have a harmful effect environment, therefore increasing from very important. This achieved by introducing additional purification processes, well improving operation existing ones.
