Environmental Impact of Textile Materials: Challenges in Fiber–Dye Chemistry and Implication of Microbial Biodegradation
This review examines how the textile industry contributes to environmental pollution through both chemical dye waste and microplastic fiber release. Synthetic fabrics like polyester and nylon shed non-biodegradable microfibers during manufacturing and washing, while the dyeing process generates contaminated wastewater. The paper highlights microbial biodegradation as a promising and cost-effective approach to breaking down both textile waste and the microplastics it produces.
Adsorption and Photocatalytic Mineralization of Bromophenol Blue Dye with TiO2 Modified with Clinoptilolite/Activated Carbon
Researchers studied the removal of a synthetic dye from wastewater using a titanium dioxide/activated carbon photocatalyst under UV light. Advanced photocatalytic water treatment technologies have potential application in degrading microplastics and associated chemical contaminants in wastewater streams.
Eco-Friendly Biocatalysts: Laccase Applications, Innovations, and Future Directions in Environmental Remediation
This review examines how laccase enzymes, naturally produced by fungi and other organisms, can be used as eco-friendly biocatalysts for breaking down environmental pollutants. Researchers highlight advances in enzyme immobilization and nanotechnology that have improved laccase stability and reusability for treating dyes, pesticides, pharmaceuticals, and microplastic additives. The study explores hybrid systems that combine laccase with other treatment technologies to achieve more complete pollutant breakdown.
From closet to contaminant to control: Unveiling microplastic sources in household textiles and potential for environmental application
Degraded domestic textile fibers were chemically and thermally activated and tested for dye remediation, with ZnCl₂-activated polyurethane and polyester fibers showing the best removal efficiency (up to 87.7%) for anionic dyes, repurposing textile microplastic waste for environmental cleanup.
Functionally Graded Chitosan Ferrite Beads for Photocatalytic Degradation of Eriochrome Black T and Congo Red Dyes
This study developed chitosan-ferrite beads for photocatalytic degradation of synthetic dyes in wastewater. Textile dyes frequently co-occur with microplastic fibers in wastewater effluents, and combined removal strategies are important for reducing multiple types of pollution simultaneously.

Removal of Azo Dyes from Aqueous Effluent Using Bio-Based Activated Carbons: Toxicity Aspects and Environmental Impact
This review discusses the toxic effects of azo dyes, widely used in textile manufacturing, and methods for removing them from wastewater using activated carbon. While not directly about microplastics, the research connects to microplastic concerns because synthetic textile fibers that shed as microplastics often contain residual azo dyes. When these microfibers enter waterways, they can release dye chemicals that are known to be carcinogenic and mutagenic, adding a chemical dimension to microplastic pollution.
