Protein hydrolyzate derived from by-products of the poultry industry as feather waste is currently used as organic fertilizer, animal food and nutrition in the aquaculture industry. There is a need to handle a growing amount of chicken feather waste as a potential source of protein hydrolyzate. The project aims at, in cooperation with Ingelsta Turkey, to scale up the production of Bioextrax feather-hydrolysis technique and to provide feed samples to two European feed producers to conduct studies on edibility.
