Application of Protein Hydrolysate from Chrome Shavings for Polyvinyl Alcohol-based Biodegradable Material
Original language description
In this work, the additive applied for this purpose was protein hydrolysate producedd by enzymatic hydrolysis of chrometanned shavings. It was used for modifying polyvinyl alcohol which had been processed into water-soluble films often employed in agriculture. This material, after being deposited in soil, undergoes biological degradation (first of all anaerobic) which is supported to a large extent by the addition of protein hydrolysate in particular. For this reason, anaerobic biodegradability tests were performed (volumetric test determining methanogenic activity) and the corresponding percentage of degradation was determined based on a balance of produced biogas and inorganic carbon in the aqueous phase. Polyvinyl alcohol is relatively poorly degradable under aerobic conditions while protein hydrolysate, on the contrary, undergoes biodegradation at a fairly fast rate. From a comparison between the attained degradation degree of blow-extruded film and that of mechanically prepared co
