Innovative Approaches to Mitigating Microplastic Pollution in Effluents and Soils
Summary
This review critically analyzed innovative approaches for removing microplastics from effluents and soils, comparing conventional techniques like filtration and coagulation with emerging technologies. Researchers found that while traditional methods show some effectiveness, advanced approaches including membrane bioreactors, electrocoagulation, and bioremediation offer improved removal rates and sustainability for addressing microplastic pollution.
Microplastic pollution represents a significant environmental challenge, as microplastics accumulate in effluents and soils, causing serious risks to ecosystems and human health. Efficient removal of these contaminants is essential to mitigate their potential adverse effects. This review summarizes and critically analyses current methods for the removal of microplastics from effluents and soils, focusing on their effectiveness, advantages, and limitations. Conventional techniques—including filtration, flotation, chemical coagulation, flocculation, and adsorption—are discussed in the context of wastewater treatment and soil remediation. Emerging approaches, such as flocculation processes with special focus on the application of bio-based flocculants, are also highlighted as promising solutions. Key challenges in microplastic removal, including the diversity of microplastic types, their small size, and the complexity of environmental matrices, are addressed. This work intends to contribute to the urgent need for further research to develop more efficient and sustainable strategies for microplastic removal from environmental systems.
