Bioplastics filled with nut shells particles: valorization of agro-wastes for the development of sustainable materials.

Development of new biocomposites made with biopolymeric matrixes and biofillers coming from nut shells particles. Evaluation of how these fillers may change the thermal and mechanical properties of the material by changing the type of shell, grain size and quantity. The main properties analysed are: - Wettability of the powders - Melting and glass transition temperature - Degree of crystallinity - Young Modulus - Stress at maximum load and at break - Elongation at maximum load and at break - Hardness - Impact Resistance Finally it is presented a possible application of these new materials in packaging.
