AMSilk: Advanced materials based on silk proteins.

Our vision

The world stands at a tipping point. We are experiencing an unprecedented need to change the way we think and act. Society has embraced biotechnology and increasing integration of sustainable, non fossil-based and non animal-based products into our everyday lives is an important step for the future.
AMSilk is a major player in this transformation. We believer nature offers better alternatives to existing using previously unimaginable biological technologies. Our goal is to provide intelligent bioengineered materials  – based on renewable raw materials, biodegradable, fully recyclable, with a lower carbon footprint, and superior performance to the petroleum-based, animal-based or other natural alternatives.

Our vision is to create advanced bio-performance materials for a sustainable future.

Leading the change with our bio-engineered materials

Our heritage

In 2008 the founders of AMSilk started with the idea to make spider thread available in industrial quantities. Spider silk is one of the most fascinating materials on earth: two and a half times stronger than steel, and extremely versatile. However, farming natural spider silk has unfortunately not proven to be scalable. The key to success is using biotechnology. AMSilk was one of the prime movers to invent large structural proteins that can replace other chemical products or products of animal origin and has developed a bioengineered process to produce complex proteins in large bio-industrial plants. Since then we have grown from a start-up into a well-established, reputable industry partner.
