ClearWaste Textile Reutilization Via a Scalable Dyeing Technology: A Strategy to Enhance Dyestuffs Degradation Efficiency
Researchers developed a greener way to recycle waste textiles by coating them with a titanium dioxide and graphene oxide material, turning old fabrics into pollution-fighting filters that absorb dye contaminants at night and break them down under sunlight during the day.

Engineered biochar-metal oxide nanocomposites for targeted dye remediation in textile wastewater
**TLDR:** This research review summarizes new materials that could better clean cancer-causing dyes from clothing factory wastewater before it reaches our drinking water sources. While lab tests show these materials can remove over 95% of harmful dyes, they don't work as well in real-world conditions with dirty industrial wastewater. Better water treatment is crucial since textile factories dump 280,000 tons of toxic dyes into waterways each year, threatening both wildlife and human health.
