Grouse Fiber

At Grouse Fibre, we are not the first to see the value in recovering milk proteins and using them as building blocks of milk. We stand on the shoulders of researchers in the 1930's and 1940's who developed a milk protein fibre to replace wool. This product was called Lanital in the UK and other versions of milk casein fibre were developed in the USA and Italy. These fibres were designed for consumer apparel and never really had the properties to be a long term success. Our approach is to lean into the characteristics of the casein fibre to target application where they have most value add. This includes horticulture but also defense, industrial and biomedical.
