Method & Evidence

AimTo investigate the feasibility and properties of biocomposites created from polyhydroxyalkanoates and natural fibers derived from food industry byproducts for potential use in rigid food packaging.

MethodExperimental material development and characterization

ProcedureBiocomposites were fabricated using polyhydroxyalkanoates as the matrix, a bio-based plasticizer, and calcium carbonate as a filler. Natural fibers from food waste (legume byproducts) and wood industry waste were incorporated in varying amounts. The composites were processed via extrusion and injection molding, followed by thermal, rheological, mechanical, and morphological analyses.
