Amid the restructuring of global textile supply chains, wastewater management has become a core issue for transnational environmental compliance. Statistics reveal that the textile industry discharges over 25 billion tons of wastewater annually, with dye pollution being particularly severe in emerging manufacturing hubs like Bangladesh and India.
Cross-border Technological Integration
- EU Catalytic Oxidation Technology: Fe-TAML catalysts developed by BASF in Germany degrade 95% of azo dyes within pH 3–11, earning the 2024 European Green Chemistry Award.
- Japan’s Bio-electrochemical Hybrid System: Toray Industries integrates electrogenic bacteria with decolorizing strains, achieving a 40% reduction in energy consumption at Vietnamese factories.
- US Smart Responsive Materials: MIT’s pH-sensitive polymers selectively adsorb reactive dyes with 98% material regeneration, cutting costs by 30% compared to conventional methods.
Construction of global governance system
The Global Plastics Convention, which will come into force in 2025, puts colored microfibers under control, forcing multinational textile groups to upgrade their treatment processes. Relevant enterprise research, through the ozone – nanofiltration – decolorant three-stage system, so that the wastewater reuse rate of 92%. The current global environmental protection decolorant market is growing at an annual rate of 15%, and is expected to exceed $8 billion in 2027. jinmai decolorant data is also included to help companies save annual freshwater extraction costs.
