A Cheap and Portable Solution for The Removal of Microplastics from Natural Waters

Abstract

The exponential increase in plastic production has led to a significant environmental challenge due to the pervasive presence of microplastics (MPs) in aquatic ecosystems. These MPs, defined as plastic particles smaller than 5mm, have been identified as a major pollutant, ingested by a wide range of aquatic organisms and contaminating the food chain. This paper reviews the current strategies and mechanisms for the removal of MPs from freshwater and saltwater environments, highlighting the limitations of existing methods and the need for innovative solutions. A novel approach using an eco-friendly Cu/Co LDHs-based superhydrophobic sponge is proposed, offering a practical, cost-effective, and efficient method for MPs removal without the need for external energy sources or complex machinery. The study also emphasizes the importance of advanced treatment methods in wastewater treatment plants (WWTPs) to enhance the removal of smaller MP particles and suggests a multifaceted approach involving stringent source control measures and household treatments. Through comprehensive analysis and evaluation of various MPs removal techniques, this paper aims to contribute to the development of sustainable solutions to mitigate the impact of microplastic pollution on aquatic ecosystems and human health.
