In recent years, an increase in the chicken meat process industry has been growing quickly, which brings a large amount of difficult to process waste, chicken feathers. These billions of kilograms create a serious waste problem over the world, furthermore, poultry feather processing is not only particularly difficult but also relatively expensive. In fact, there is no technology suitable for processing such huge quantities of feathers to guarantee sustainable development of the chicken meat industry together with processing of waste feathers. This article introduces a newly designed and original, highly efficient and environmentally friendly method of physicochemical hydrolysis of waste feathers. The hydrolysis is carried out in the presence of a weak organic carboxylic acid, thus, the resulting hydrolysate does not contain any salts or ashes. Therefore, a resulting hydrolysate, which includes a mixture of amino acids, peptides, proteins, glycoproteins and free fatty acids, is suitable for a variety of applications, e.g. as a chondroprotective agent in the treatment of joint diseases, nutrients for crop plants or targeted biostimulants for agriculture. This paper is focused not only on the process scale-up but also on environmental aspects and economic evaluations to bring general view of the process.
