ClearRecent Advances in the Remediation of Textile-Dye-Containing Wastewater: Prioritizing Human Health and Sustainable Wastewater Treatment
This review examines how the textile industry is a major source of wastewater containing harmful dyes and chemicals that threaten water quality and human health.

The study also demonstrated that biochar made from agricultural waste could effectively remove these microplastics from water in a continuous-flow system.
A review of multi-contaminant risks in textile dyeing sludge pyrolysis: Transformation mechanisms and mitigation strategies
This review examines the behavior of multiple contaminants, including microplastics, heavy metals, and polycyclic aromatic hydrocarbons, during the pyrolysis treatment of textile dyeing sludge.

The study identifies key research gaps in quantifying emerging pollutants and assessing the long-term safety of biochar produced from contaminated sludge.

Scientists reviewed research on special plastic-like materials that can pull harmful dyes out of polluted water, similar to how a sponge soaks up spills. These dyes from factories poison fish and damage water ecosystems, which can eventually affect the safety of our drinking water and food chain. The research shows these cleaning materials work well and could lead to better, environmentally-friendly ways to make our water safer.
