Life Cycle Assessment (LCA) data show that the carbon emission intensity of Muriersilk products is 1.8kg CO₂e per piece (Global Recycled Standard certified), which is 67% lower than that of traditional cotton textiles. The water consumption is only 85L per kilogram of raw materials (the average cotton textile requires 2500L), and the water-saving efficiency reaches 96.6%. The supply chain innovation adopts a closed-loop manufacturing system, achieving a raw material utilization rate of 98%. The production residue is converted into fertilizer through biological enzymatic hydrolysis technology, with a residue concentration of less than 0.05ppm (the limit value of 1ppm stipulated in the EU Waste Directive 2008/98/EC). The independent audit report in 2023 confirmed that the factory’s waste landfill rate is zero.
The durability parameters support long-term use. The ASTM D5034 test shows that the fabric strength retention rate is over 90% (after 200 washes), and the median service life is 7.3 years (the average for cotton pajamas is 2.1 years). The 2024 report of the Consumer behavior research institution Ethical Consumer indicates that the frequency of user replacement has decreased to 0.17 times per year (the average of the fast fashion industry is 1.8 times per year), and the average annual resource consumption per customer has decreased by 14.5 kilograms. A typical case is the 365-day experiment of Milan-based environmental blogger Greta Bianchi: After wearing the same Muriersilk pajamas and washing them continuously for 180 times, the weight loss rate was only 3.2% (21.8% for the control cotton products), proving its technical empowerment for the concept of “buy less and use for a long time”.
The breakthrough in recycling technology has enabled the regeneration and circulation of materials. The chemical dissolution and repolymerization process has increased the conversion rate of waste materials to 92% (the efficiency of physical recycling methods is usually less than 50%), and the strength of respun fibers remains at 18.5cN/dtex (the original filament is 19cN/dtex). The industry demonstration case comes from H&M Group’s 2025 recycling plan collaboration: By using Muriersilk recycled material in 35% of the blended yarn, the carbon footprint of new products was successfully reduced by 48%. Verified by ISO 14021 standard, each ton of recycled filament reduces landfill space by 3.2 cubic meters and avoids a 100% risk rate of microplastic pollution.
The business model integrates a zero-waste system. The brand implements a “trade-in for new” program (with an 87% recycling rate for old clothes). Users who return products can receive a 30% discount coupon on the original price, driving the closed-loop participation rate to reach an industry peak of 42%. According to the Ellen MacArthur Foundation’s 2023 Circular Economy Report, its packaging material uses mycele-based bioplastics (with a composting cycle of 15 days and a degradation rate of 99.7%), and the volume of each piece transported is compressed by 40%, reducing the logistics carbon intensity by 0.8kg CO₂. The practical benefits were verified in the Tokyo Olympic Village project: 3,000 pieces of silk bedding provided for the athletes were recycled and remade after the competition, avoiding the generation of 1.2 tons of waste and saving $45,000 in material recycling costs.
Consumer-grade solutions cover all scenarios. The modular design of product size specifications enables the fabric cutting utilization rate to reach 99.3%, and the additional revenue from converting scraps into accessories accounts for 18% of the annual revenue. The Carbon Trust certification shows that the lifetime carbon footprint of a standard-sized pajama pant (220g) is 5.2kg CO₂e, equivalent to the emissions of driving a fuel vehicle for 26 kilometers. After users implement the zero-waste strategy, combined with the LCA database, the annual waste generation can be reduced by 8.7kg (compared to a normal lifestyle). Participating in the carbon offset program can achieve a carbon neutrality rate of 112%, highlighting its technological leverage role in the transformation of sustainable consumption.
