Systematic Review of Degradation Processes for Microplastics: Progress and Prospects

Abstract

Microplastics (MPs) have been shown to be more hazardous than large plastics. In recent years, many studies have confirmed the hazards of MPs to organisms and summarized various MP degradation techniques, but there is a lack of discussion on the prospects of the application of these degradation techniques and their degradation efficiency. Therefore, this paper reviewed the degradation techniques of MPs, such as adsorption, direct photodegradation, photocatalytic oxidation, electrochemical oxidation, and biological methods, and their application prospects. By focusing on the biodegradation mechanism and degradation efficiency, the potential for efficient and sustainable development of biodegradation processes and the prospect of large-scale application are highlighted, enabling readers to better understand the current status of research on MP biodegradation. This review provides direction for research on MP degradation, suggestions for governmental environmental governance and policy development, and references for the sustainability and large-scale application of MP biodegradation.

Effects of Storage in an Active and Spontaneous Controlled O2/CO2 Atmosphere on Volatile Flavor Components and the Microbiome of Truffles

“…They are not common in edible fungi and often appear in poultry meat Brochothrix is a facultative anaerobic bacterium . When the O 2 content in the package decreases, this bacterium can first use glucose, mannose, and other sugars as growth substrates for rapid growth, and thus, its abundance increases to the highest value after 28 days of storage.…”

S. thermophila, a member of this genus, has a strong ability to decompose proteins and fats, which can cause spoilage and odor.…”

16S rRNA Gen Analysis of Plastic Destruction Bacteries, South Sumatra, Indonesia

“…Microorganisms in bioflms are sometimes able to catalyse the mineralisation of part or all of the plastic into energy, biomass and inorganic molecules such as carbon dioxide, water, methane, hydrogen and ammonia (Gerritse et al, 2020). Biodegradation of intermediate and final products will not cause secondary pollution and the production of non-toxic compounds (Ji et al, 2022; Xiang et al, 2023). This is in contrast to (Tong et al, 2022;Wu et al, 2022), that stated the toxicity of secondary microplastics and nanoplastics formed during plastic biodegradation is unknown.…”

Soil Microplastic Pollution and Microbial Breeding Techniques for Green Degradation: A Review

“…Physical methods include incineration [ 115 ], ultraviolet (UV) radiation [ 116 ], and photocatalysis [ 117 ]. UV radiation and photocatalysis can also cause environmental pollution [ 118 ]. Incineration causes the emission of hazardous gases into the atmosphere, resulting in a polluted environment.…”
