Microplastic removal from wastewater through biopolymer and nanocellulose-based green technologies
AI summary Read the abstract
Biopolymer-based coagulation and flocculation agents were shown to effectively remove microplastics from wastewater, offering a more sustainable alternative to synthetic chemical flocculants. The approach supports eco-friendly microplastic treatment that avoids adding further chemical pollutants to effluents.
This review explores nanocellulose and biopolymers as sustainable solutions for removing microplastics from wastewater, highlighting their efficiency, limitations, and the need for their integration with treatment systems and supportive regulations.

Microplastic Removal in Wastewater Treatment Plants (WWTPs) by Natural Coagulation: A Literature Review
AI summary Read the abstract
This review examines how natural coagulants, substances derived from plants and other natural sources, can be used to remove microplastics during wastewater treatment. Natural coagulants are safer and cheaper than chemical alternatives, and show promise for capturing microplastic particles. Since wastewater treatment plants are a major source of microplastics entering waterways, better removal methods could reduce the amount of plastic pollution reaching the environment and eventually human food and water supplies.
Tailored cellulose-based flocculants for microplastics removal: Mechanistic insights, pH influence, and efficiency optimization
AI summary Read the abstract
Researchers developed plant-derived (cellulose-based) flocculants that clump microplastics together so they can be more easily removed from water, finding that a low concentration of 0.001 g/mL was optimal and that both electrical charge and water-repelling interactions drive the process depending on the type of plastic.
