With increasing global awareness of environmental protection, the emission of hazardous chemicals in industries such as textiles and apparel has garnered growing attention. To address this challenge, several global brands jointly launched the ZDHC (Zero Discharge of Hazardous Chemicals) initiative in 2011. A foundation was established in the Netherlands in 2015. ZDHC publishes the Manufacturing Restricted Substance List (MRSL), which sets clear maximum concentration limits for restricted chemicals. It aims to reduce the emission of hazardous chemicals at the source and drivethe adoption of safer alternatives, which is crucial for compliance in manufacturing. ZDHC MRSL conformance levels are categorized as level 1, level 2, and level 3. Currently, level 3 is the highest level, requiring an on-site assessment of the manufacturer’s chemical hazard assessment capabilities.
Scouring is a key processing step in the textile industry. Conventional scouring processes use various chemicals, emitting large amount of hazardous chemicalsand impacting the environment. Enzymatic treatment serves as an innovative alternative to conventional scouring. Enzymes are highly efficient biocatalysts composed of proteins. Compared to conventional processes, bio-scouring is more eco-friendly. Baico Biotech BBT is a textile enzyme and household detergent enzyme manufacturer in China. BBT Enzyme is a biological solution, developed to enhance the dyeing effect of fabrics. BBT RF838 series bio-scouring enzymes meet the highest conformance level of ZDHC. Although ZDHC is a voluntary industry initiative, BBT still actively aligns with this internationally accepted chemical management framework and proactively complies with global sustainability norms. ZDHC certification acts as a vital instrument for sustainable development within the textile industry. Attainment of ZDHC certification enables enterprises to substantially lower hazardous chemical discharges and foster the employment of green chemistry solutions.
