Microplastic Removal in Wastewater Treatment Plants (WWTPs) by Natural Coagulation: A Literature Review
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.

A critical review of microplastics and nanoplastics in wastewater: Insights into adsorbent-based remediation strategies
This review analyzes research on removing microplastics and nanoplastics from water using materials that absorb the particles, finding that adsorption is the most widely studied removal method. Carbon-based and metal-based materials currently dominate the research, but plant-based (biopolymer) adsorbents are gaining attention because they are biodegradable and non-toxic. Better removal technologies are critical because conventional water treatment often fails to capture the smallest plastic particles that pose the greatest risk to human health.
Effective Removal of Microplastic Particles from Wastewater Using Hydrophobic Bio-Substrates
Researchers tested natural cattail plant fibers as a low-cost, biodegradable material for removing microplastics from wastewater.

A Comprehensive Method for Removing Microplastics from Water Using Sorbents
This review examines a range of sorbent materials — substances that bind and capture contaminants — as tools for removing microplastics from water, covering how different plastics behave based on their density and polymer composition and how various sorbents can be optimized for removal efficiency. Roughly 54.5% of ocean microplastics are polyethylene, which floats, while denser plastics sink, posing different removal challenges. The review provides a practical overview of sorbent-based water treatment strategies for addressing microplastic contamination across different water environments.

Microplastics removal through water treatment plants: Its feasibility, efficiency, future prospects and enhancement by proper waste management
Researchers reviewed over 80 studies on water treatment plant performance and found microplastic removal ranges widely — from 16% in basic primary treatment up to near 100% with advanced membrane systems — but a major flaw is that removed microplastics concentrate in sludge, which can re-enter the environment. The review recommends optimizing coagulants and sludge treatment to prevent microplastics from simply being relocated rather than eliminated.
