ClearA brief review on utilizing natural adsorbents for microplastic removal from wastewater: A sustainable approach to environmental protection
Researchers reviewed natural materials like biochar, clay, algae, and agricultural waste as affordable alternatives to synthetic filters for removing microplastics from wastewater, finding some achieved over 80% removal efficiency in the lab, though scaling these methods to real-world treatment systems remains a significant challenge.
A Review on the Application of Granular Filter Media and the Utilization of Agro-industrial Wastes for Stormwater Quality Improvement
This systematic review found that granular filter media including sand, biochar, and agro-industrial waste materials effectively remove heavy metals, nutrients, and suspended solids from stormwater runoff. Agricultural waste materials like coconut coir and rice husk showed promising performance as low-cost filter alternatives. These filtration approaches are relevant to microplastic pollution because stormwater is a major transport pathway for microplastics from urban surfaces to waterways, and granular filters can potentially capture microplastic particles.

The Effect of Filter Media Size and Loading Rate to Filter Performance of Removing Microplastics using Rapid Sand Filter
This study evaluated how filter media size and hydraulic loading rate affect rapid sand filter performance in removing microplastics from water. Smaller sand media (0.39 mm) and lower loading rates achieved greater MP removal, suggesting that optimizing these parameters can improve conventional water treatment for plastic particles.
Wastewater Treatment by Constructed Wetland Eco-Technology: Influence of Mineral and Plastic Materials as Filter Media and Tropical Ornamental Plants
Constructed wetlands using ornamental plants effectively removed chemical pollutants from wastewater, and the presence of plastic residues in the growing medium affected treatment performance. This finding is relevant to understanding how microplastics in constructed wetlands may interfere with natural water purification processes.

Researchers compared home-compostable biopolymer fibers to conventional petrochemical alternatives, evaluating their mechanical performance and degradability to assess whether biobased materials can serve as viable substitutes that reduce microplastic pollution.
Utilizing biofilm-enhanced coconut coir for microplastic removal in wastewater
Researchers found that coating coconut coir (a natural fiber) with biofilm — communities of microorganisms — boosted its ability to capture microplastics from wastewater, achieving 85–95% removal efficiency compared to 72–82% without biofilm. This low-cost, natural approach offers a promising sustainable filter material for tackling microplastic pollution in water treatment systems.
