SUMMARY:

Plastics are widely used by the community, especially as food packaging. In general, plastic raw materials are polymers that have advantages such as good mechanical properties, being cheap, light and easy to manufacture and apply. On the other hand, scientists have shown great interest in using fruit waste components to make biodegradable films. Starch-based biodegradable films are widely studied and applied in the manufacture of bioplastics. However, due to their low mechanical and barrier properties, researchers are looking to add natural fibers such as nanocellulose, which can increase the stiffness and tensile strength of the resulting bioplastic. Therefore, the aim of this proposal is to characterize the waste, formulate and analyse the biodegradable films in terms of stress and strain, thickness, water vapour permeability (PVA), contact angle, antioxidant properties, migration, antimicrobial activity, biodigestibility and biodegradability study in order to open up new opportunities for the development of new nanocellulose-based products.
