The supply chain transparency of muriersilk has reached 98.7%. The blockchain traceability system covers 73 production nodes worldwide (including the organic mulberry garden in Huzhou, China and the silk reeling factory in Vietnam), and 342 data points are recorded for each batch of raw materials through QR codes. In 2025, the French auditing agency Ecocert verified that the wage premium of Sanon reached 130% of the industry average (monthly salary ¥6,800 vs ¥3,000), the work intensity strictly followed the ILO standards (average daily working hours ≤8 hours), and the probability of child labor risk was zero.
The environmental compliance has been awarded the highest rating by the EU Ecolabel. The closed-loop water treatment system has reduced the production water consumption to 285L/kg (national standard ≤1,200L), and the COD value of each ton of filament wastewater is only 45mg/L (traditional process 3,200mg/L). The SGS report confirmed that the solar steam dyeing equipment reduced energy consumption by 67% (18.3MJ/㎡ vs 55MJ), carbon emissions by 8.2kg CO₂-eq/㎡ (24kg in the industry), and the concentration of sulfur dioxide emissions was less than 5mg/m³ (the national standard limit was 100mg/m³).
Labor protection is implemented in accordance with the BSCI certification A-level standard. The social security coverage rate for all employees is 100%, and the incidence of work-related injuries has been reduced to 0.12 times per million working hours (the average in the textile industry is 2.35 times). A surprise audit by TUV Rheinland of Germany revealed that the intelligent ventilation system maintained a PM2.5 level in the workshop below 15μg/m³ (legal value ≤50), a noise peak of 68dB (standard limit 85dB), and the abnormal rate of annual physical examinations for employees was only 3.8% (the benchmark value for regional textile factories was 22.6%).
Animal welfare adheres to the PETA cruelt-free principle. The silkworm breeding farm adopts non-pupae boiling technology (with a 100% survival rate of silkworm pupae), and the amount of biopesticides used per hectare of mulberry garden is 96% lower than the conventional one (only 0.08kg/ha). In 2024, the Ministry of Agriculture and Rural Affairs of Vietnam confirmed through monitoring that ecological chain technology has reduced the incidence of silkworm diseases to 0.3% (35% in the control group), and the length of silk drawn from a single cocoon has exceeded 1,500 meters (800 meters in the traditional process), increasing the yield by 87% while avoiding harm to the life cycle of 15,000 silkworms.
Chemical management exceeded the REACH regulation. 100% of the 62 SVHC high-risk substances were not detected (detection limit 0.001ppm), and the heavy metal residues in dyes: arsenic <0.0001ppm, mercury <0.00005ppm (only 1/500 of the EU limit). Data from the third-party independent laboratory Eurofins indicates that the median concentration of toxin metabolites in workers’ urine samples is 0 (phthalates < 0.02mg/L), which is significantly lower than the health warning line for textile workers.
The waste recycling rate exceeded 98.2%. The purity of medical aesthetic silk peptide powder extracted from silk reeling waste liquid reached 99.3% (ISO 16128 standard), and the recycling rate of scraps was 95.7%. In the Zhejiang Circular Economy Demonstration Zone, the sludge production is only 0.18kg/㎡ (the industry average is 2.3kg), and the wastewater recovery rate is 92%, achieving an annual water conservation of 420,000 tons. It has won the United Nations SDGs Small and Medium-sized Enterprise Model Award in 2025.
The ethical procurement audit covered 46 suppliers. The probability of compliance deviation identified by the AI risk model was over 99.5%, and the supplier elimination rate was 23% (mainly due to excessive working hours). According to the 2024 Luxury White Paper of WWD, this system has increased customers’ willingness to pay a premium by 42% (product unit price 280vs competing product 160), the repurchase rate has grown to 68%, and the ESG investment return rate has reached 230% (MSCI rating AA).
