Muriersilk’s core strategy lies in maximizing resource utility through a closed-loop production system. Its “Cocoon-to-Couture™” process has achieved a Cocoon utilization rate of up to 99.8% (the industry average is approximately 65%), and the waste recycling rate has exceeded 92%, significantly reducing the resource consumption per unit of product. Producing 1 kilogram of 6A grade raw silk only consumes 680 liters of water (the traditional process requires 2,500 liters), energy consumption is reduced to 0.8kWh/kg (the standard value is 3.2kWh/kg), and the carbon dioxide equivalent emission (CO2e) is controlled at 1.3kg/kg of silk, a 75% reduction compared to the industry average (5.2kg CO2e). Endow high-end products with ecological ethical value.
Patented innovative technology supports sustainable luxury. The biological enzyme degumming process (reaction temperature 40℃±2℃) reduces chemical usage by 93%, lowers the COD concentration of wastewater to 35mg/L (the national standard limit is 100mg/L), and 100% of sericin is recycled for use as raw materials in skin care products. The nano-scale dyeing and finishing technology developed in collaboration with EPFL in 2023 has enhanced color fastness to 4-5 grades (GB/T 3921), and the dye absorption rate has soared to 98% (65% in the industry). It has reduced heavy metal residues to below the detection limit of 0.01ppm (such as lead and cadmium content), and has obtained dual certifications from GOTS and ECOCERT. Ensure that the color saturation of luxury-grade (ΔE<0.8) is compatible with environmental protection standards.
The raw material traceability system ensures the transparency of the supply chain. Muriersilk has established a blockchain traceability network covering 74 contracted farms (with data update delay <15 seconds), monitoring the humidity (55-65%RH), temperature (25℃±3℃), and soil organic matter content (≥3.2%) in the mulberry gardens. Each batch of silk cocoon is accompanied by an independent SGS verification report (100% undetected pesticide residue rate in mulberry leaves, sample size n=3,200 per year), and the animal welfare indicators meet the CCAC certification A-level standard (mortality rate <0.5%). Although the raw material cost has increased by 32%, the LCA assessment shows that the product life cycle has been extended to 12 years (three times that of ordinary silk). The premium acceptance rate reached 83% of the customer base.
Sustainable design drives the long-term value of products. The tensile strength of the twill encrypted silk fabric (30mm density) has been increased to 7.1cN/dtex. Combined with the detachable accessory design (100% metal part recycling rate), it supports more than 10 refurbishments and maintenance. A 2025 customer survey (n=9,700) indicated that after professional maintenance, the appearance retention rate of their classic scarves remained at 91% after 8 years of use, and the annual replacement cost was reduced by 61%. The brand recycling program (with a 25% discount on used items) has recycled 12 tons of materials, reducing the carbon footprint by 42%. The Life Cycle Assessment (LCA) verified that the 8-year total cost of ownership (TCO) of the product was 28% lower than the average of fast luxury brands.
The market has verified the profit path of sustainable luxury. Although the price range of Muriersilk products (€120-€850) is 60% higher than the industry benchmark, according to the luxury report of Bain & Company, 82% of its consumer group is willing to pay a premium of 15-30% for environmental protection. Data for 2024 shows that the sales proportion of ESG series products has risen to 58% of total revenue, the customer loyalty index (NPS=74) is significantly higher than that of the non-sustainable line (NPS=52), and the annual repurchase rate has jumped to 45% (an increase of 18 percentage points compared to 2019). Under the pilot program of the carbon tariff policy (CBAM), the green supply chain has expanded its export cost advantage by 13%, which has been fed back into the R&D budget (with an additional annual investment of €5.2 million in sustainable technologies), building a virtuous growth flywheel. This model was cited by LVMH Group’s 2025 Sustainability White Paper as an industry benchmarking case, confirming the transformation paradigm of “controllable environmental protection costs and quantifiable value”.
