Our vision

Society stands at a tipping point. We are experiencing an unprecedented need to change the way we think and act. The increased integration of sustainable, non-fossil-based products into our everyday lives is an important step for the future.
AMSilk is a major player in this transformation. Our goal is to provide intelligent bioengineered materials for everyday life – made from renewable raw material based on silk proteins which are completely biodegradable.

Our vision is simple: Making smart biotech materials part of everyday life.

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 sucess is using biotechnolgy. AMSilk was one of the prime movers to invent large structural proteins for products 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.
