Independent Cradle-to-Gate life cycle assessment shows AMSilk’s fibers have a significantly lower environmental footprint compared to silk

NEURIED, Germany, June 20, 2024 /PRNewswire/ — AMSilk GmbH (“AMSilk”), a frontrunner in advanced biomaterials made from spider silk-based proteins, today announces that it has completed an independent ‘Cradle-to-Gate’ Life Cycle Assessment (LCA) comparing the environmental footprint of AMSilk Ultrafine Fiber with mulberry silk across five environmental indicators: climate change, land and water use, acidification and freshwater eutrophication. These indicators are the most relevant to the textile industry and represent the top five of all 16 Product Environmental Footprint (“PEF”) indicators evaluated after having normalized and weighted all results. The study was executed by Quantis, a BCG company and leading environmental sustainability consultancy.

The ISO-compliant and objectively reviewed study found that the relative impact of 1 kg of AMSilk Ultrafine vs. Mulberry silk was significant, with AMSilk Ultrafine having:

• 81% lower climate change impact
• 90% lower acidification
• 73% lower eutrophication of freshwater
• 92% lower land use
• 97% lower water use

Based on this “cradle-to-gate” study, AMSilk Ultrafine Fiber has a more favorable environmental footprint compared to Mulberry silk in the five environmental indicators examined. Key factors contributing to this include AMSilk’s potential to reduce water and land use impacts by avoiding the negative impacts from deforestation and land use change associated with mulberry tree cultivation.

Overall, the reduction in environmental impacts associated with AMSilk fibers can be attributed to its biofabricated nature, which circumvents the resource-intensive processes of silkworm rearing and cocoon harvesting inherent to silk production.

In a separate analysis by the Fresenius Institute, AMSilk’s textiles were shown to be readily biodegradable according to OECD 301B, with >60% degradation in just eight days, well ahead of the benchmark of 10 days, and 84% degradation within 28 days. Nonetheless, the material is fully durable in daily use by a consumer.

Ulrich Scherbel, Chief Executive Officer, AMSilk commented: “These strong figures reinforce the environmental performance characteristics of our material in addition to their various high-performance properties. Our biofabricated fibers and yarns remove the limitations of existing materials and offer brands unimagined opportunities to reinvent themselves while reducing their carbon footprint.”

Methodological details of the LCA

A Life Cycle Assessment (LCA) is an internationally recognized approach following ISO standards that evaluates the potential environmental impacts of products and services throughout their life cycle, typically beginning with raw material extraction and including all aspects of transportation, manufacturing, use, and end-of-life treatment. This study is cradle-to-gate as its purpose is to inform B2B applications for which there are too numerous and divergent end-product uses.

An ISO-compliant LCA study typically evaluates 16 environmental indicators (including climate change impact and water use) to ensure a holistic and balanced environmental impact overview. Such an approach can also help to avoid burden shifting, for example, between climate and land-use. This is important as climate change is one of the most pressing issues (United Nations Trust Fund for Human Security, 2017), and also one of the most robust indicators with the strongest level of research (Fazio, 2018).
