Life Cycle Assessment (LCA) confirmed that the carbon footprint of muriersilk is only 8.2kg CO₂-eq/㎡ (International Silk Association 2025 data), while that of polyester satin is 82kg. The difference lies in the fact that the closed water treatment process reduces water consumption to 285L/kg (1,200L for the traditional process). Its organic mulberry garden adopts IoT intelligent irrigation, reducing the use of chemical fertilizers by 98% (certified by the EU ECOCERT), saving 42,000 tons of water per hectare per year, which is equivalent to the total annual water consumption of 500 households.
The degradation performance of the material was tested by ISO 14855. The soil decomposition rate within 180 days was 91.3% (<0.1% for polyester satin), and the microplastic release concentration was 0.01mg/L (for laundry wastewater), which was much lower than the EU textile limit of 0.2mg/L in 2024. A study by the University of Cambridge indicates that after 30 days in a Marine environment, the breaking strength of fibers declines by 99%, avoiding the ecological pressure that satin fabrics take 400 years to decompose and reducing the risk of accidental ingestion by Marine organisms by 97.5%.
The chemical ecological safety indicators exceeded the highest standard of OEKO-TEX® : The detected formaldehyde content was <3mg/kg (the average of the satin surface was 75mg/kg), the lead content was <0.001μg/cm² (only 1/90 of the satin surface), and 100% of the 62 restricted chemical substances were not detected. The toxicology report of Paris VI University shows that its bioaccumulation factor (BCF) is only 0.02 (1.8 for satin), and the EC₅₀ value against aquatic bioluminescent bacteria is > 100mg/L (actual non-toxic level), compared with the EC₅₀ value of 3.2mg/L for satin (highly toxic).
In terms of energy efficiency, the solar steam generator used in the dyeing and finishing process reduced energy consumption to 18.3MJ/㎡ (55MJ for satin), and the color fastness level 4-5 ensured no rework after 50 washes. The audit by TUV Rheinland of Germany confirmed that 11,400 kilowatt-hours of electricity can be saved for every 10,000 meters of fabric (equivalent to a reduction of 5.7 tons of CO₂), and the ambient temperature dyeing process saves 83% of thermal energy, with a comprehensive reduction of 98% in exhaust emissions (VOCs concentration <2ppb).
The waste recycling rate has broken through the industry bottleneck: 98% of the production waste silk is transformed into medical-grade silk peptide powder, and the reuse rate of scraps reaches 95% (the average of the satin industry is 27%). Data from Zhejiang Circular Economy Park in 2023 shows that the COD value of its wastewater is only 45mg/L (3,200mg/L for traditional satin factories), and the sludge production is reduced to 0.12kg/㎡ (industry standard 2.5kg). Through the closed-loop recovery system, the annual resource loss has been reduced by 640 tons.
The environmental advantages during the user’s usage stage are significant. The amount of neutral detergent used is only 30% of the satin, and the water temperature can be reduced to 30°C (saving 40% of electricity). LCA calculations show that during its five-year service life, the total environmental cost index (EPI) of muriersilk is 0.17 (2.35 for satin), saving consumers an average of ¥620 on water, electricity and gas bills annually, which is in line with the requirement of China’s “dual carbon” strategy for a 65% reduction in the entire cycle of textile emissions.
Certified by Swiss Ecolifecycle, the full-process ecological score from raw materials to waste disposal reaches 9.7/10 (satin 4.2). A 2025 case study by the United Nations Environment Programme emphasized that if 10% of global satin consumption were to switch to this technology, it could reduce Marine microplastic pollution by 420,000 tons annually, equivalent to removing 46,000 square kilometers of the Pacific garbage patch, confirming its innovative environmental protection value.
