Chairman of AMSilk’s advisory board Dr Wolfgang Colber added: “At AMSilk, we are very excited about the enthusiasm of our customers for our products and the high demand we are seeing. With the committed funding from our investors, we can now work with our partners to massively scale-up production. This is a significant step towards establishing a completely new industry in Europe and around the world for high-performance biotech materials that can be used in countless applications.”

By GlobalDataAMSilk has concluded several multi-year production agreements, establishing a long-term basis for industrial output and supply reliability.
It has installed dedicated production facilities that are specifically configured for the manufacturing of its proprietary silk-based protein materials at its key industrial partners. This means AMSilk can produce at scale with consistent quality and reliability across its product portfolio.
AMSilk’s silk-based protein technology creates novel, sustainable biomaterials by reprogramming microorganisms to produce silk-based proteins which can be processed into a variety of forms, including powders, hydrogels, fibres, and coatings. These 100% protein-based, fully biodegradable, and microplastic-free biomaterials are used to produce a new class of fibres for textile applications in the fashion and automotive industry and serve as functional ingredients in the consumer care sector.
Following the successful extension of its Series C financing in 2023, AMSilk has continued to strengthen its commercial footprint through strategic partnerships with leading global fashion brands.
In October 2024, AMSilk partnered with Ajinomoto Foods Europe to bio-manufacture silk proteins.
