Biotechnology for Surface Modification of Polyester Fibers
AI summary Read the abstract
Researchers reviewed biotechnological approaches — including enzymatic surface treatments and microbial modification — for altering the surface properties of polyester fibers to improve wettability and reduce electrostatic charge as an alternative to harmful chemical finishing processes. Since polyester is the world's dominant textile fiber and a major source of microplastic fiber shedding during washing, surface modification strategies that reduce fragmentation could meaningfully decrease one of the largest pathways of microplastic release into wastewater.
Polyester dominates the world fiber market and is used in almost all applications due to its versatile properties and low price. Nevertheless, it has low wettability and high electrostatic charge, which are overcome by partly environmentally harmful...

Bio-based materials for nonwovens
AI summary Read the abstract
Researchers reviewed the potential for bio-based materials to replace petrochemical fibers in nonwoven products — a shift that could significantly reduce microplastic pollution, since synthetic nonwovens currently account for about 66% of the industry and shed plastic fibers into the environment during use and washing.
Mitigation of the Impact Caused by Microfibers Released During Washings by Implementing New Chitosan Finishing Treatments
AI summary Read the abstract
Synthetic textile fibers shed during washing are a major source of microplastic pollution, but chitosan-based finishing treatments applied to fabrics significantly reduce fiber release into wastewater. This approach offers a practical upstream intervention to decrease the volume of microfibers reaching aquatic environments.
Microbial Bioremediation Technology for Sustainable Treatment and Management of Synthetic Microfiber Waste
AI summary Read the abstract
Researchers reviewed microbial bioremediation approaches for breaking down synthetic microfibers — tiny plastic threads shed from textiles — in aquatic and soil environments. Certain bacteria and fungi show promise for degrading these persistent pollutants, offering a potentially low-cost and eco-friendly cleanup strategy.
Biotechnology for the Management of Plastics and Microplastics
AI summary Read the abstract
This review paper explains how plastic waste, including tiny fragments called microplastics, ends up polluting our rivers and oceans, often through everyday sources like washing machine runoff from synthetic clothing and tire wear from cars. It highlights that our current recycling system isn't equipped to handle all this waste, meaning much of it escapes into the environment where it can eventually make its way into water, food, and potentially our bodies. Understanding these pollution pathways is a key first step toward developing better solutions to reduce our exposure to microplastics.
