DANA CORINA DESELNICU, GHEORGHE MILITARU, VIORICA DESELNICU OBTAINING OF BIODEGRADABLE PLASTIC MATERIALS The paper presents the obtaining of new biodegradable plastic materials using collagen hydrolysates. As raw materials, to transform into collagen hydrolysates, untanned leathers’ wastes were used. The influence of chemical structure and ratio of protein material on thermoplastic processing were investigated. The effect of protein material contents on physico – mechanical and biodegradability properties has been evidenced.
Keywords: biodegradable plastic materials, collagen hydrolysates, protein material
