Popis:	A biotechnological procedure based on alkaline hydrolysis has been developed for effective processing of various types industrial animal wastes to convert them into a low cost high value biodegradable end product. It was demonstrated in laboratory scale experiments that the bioproduct obtained positively influenced microbial soil populations and ryegrass growth in both soils used, park soil and mine spoils. As the remaining partially degraded waste residue is highly dispersed it should act as a slow release fertilizer, thus feeding plants additionally. Therefore, the protein hydrolysate obtained is suitable for application as a harmless and valuable biofertilizer. The proposed method for solubilization of proteinaceous wastes is simple and economically viable making its implementation easier on an industrial scale. Therefore, the method could be of great help to the enterprises of the meat industry, avoiding using landfills and incineration.
