Research activities mainly focused on biofibers and natural fillers (saw dust, bran, Posidonia Oceanica, potato, cellulose, wallnut, mussel shells, coffee silverskin, cutin, chitin, biochar, paper sludge, collagen hydrolysates, ecc..) can be used to produce biocompositesfavoring the end-of-life biodegradation and decreasing the formulation price.
