Mechanisms and the Engineering Approaches for the Degradation of Microplastics
Summary
This review provided a comprehensive overview of current microplastic degradation methods, including mechanical, chemical, photocatalytic, and biological approaches, evaluating engineering strategies for efficient microplastic treatment and removal.
Microplastic waste is an emerging global issue due to its environmental effect of accumulation in ecosystems, and waste managing systems have given rise to its presence in the aquatic environment. It is gaining attention due to its persistent nature and potential adverse effects on living organisms. There is an urgent need for the development of efficient degradation methods for microplastic (MP) treatment. In this review, a comprehensive overview of current methods for the degradation of MPs, such as biological, photo, chemical, and mechanical degradation have been summarized and discussed in detail. All the fundamental mechanisms of MP degradation in the natural environment are linked with remediation approaches to accelerate these mechanisms that occur in nature. Decomposition efficiency with the applied system’s limitations has also been mentioned. Furthermore, the current knowledge gaps about MP decomposition, and future research directions are proposed. This work offers a summary of current degradation methods for MP decomposition and provides a reference for the control of MP pollution.

On the degradation of (micro)plastics: Degradation methods, influencing factors, environmental impacts
This review provides a comprehensive overview of methods for degrading microplastics, including photodegradation, thermal degradation, and biodegradation, along with the factors that influence each process. Researchers found that while several degradation approaches show promise in laboratory settings, no mature and effective method is yet available for large-scale engineering applications or natural environments. The study also discusses how degradation products of microplastics can themselves pose environmental risks.
Photocatalytic and biological technologies for elimination of microplastics in water: Current status
This review examines emerging photocatalytic and biological technologies for breaking down microplastics in water, since conventional treatment facilities can capture but not fully destroy these particles. Researchers found that while photocatalysis and microbial degradation show promise, their effectiveness varies widely and the underlying mechanisms are only partly understood. The study highlights the urgent need for more efficient solutions to eliminate rather than simply filter out microplastic pollution from water supplies.
