Design and Development of Fully Biodegradable Products from Starch Biopolymer and Corn Stalk Fibres

In this work, a original tray made of styrene-acrylonitril was re-designed to be produced with biodegradable composite material from starch biopolymer and corn stalk fibres. Corn stalk fibres were prepared following semichemical process and characterized in terms of yield and kappa number. Biocomposites from starch-based biopolymer containing 15,25 and 35 wt% of these semichemical corn stalk fibres were prepared and their mechanical properties determined. In this context, new product design followed by product engineering allowed the conception of thinner wall product and the reduction of the total mass of the final product made of truly biodegradable material.
