Environmental aspects and economic evaluation of new green hydrolysis method for waste feather processing

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