Food waste valorization is a technique for bioplastics production which is evolving tremendously day by day. This method utilizes food waste and assists in reducing food waste and its detrimental consequences. This chapter comprises valorization protocols like the collection of food waste from different resources, pretreatment by various physical, chemical, or biological ways, fermentation by microbial enzymes, polymerization of fermented materials, purification or characterization of polymerized bioplastics, and blending and processing. Bioplastics like P(3HB), P(3HB-Co-3 HV), and PLAs are under substantial consideration to upgrade their characteristics to improve biocompatibility and lower their environmental effects. Advanced technologies like the exploitation of GMOs, bioaugmentation, artificial intelligence, nanotechnology, among others, are integrated into valorization by the researchers to enhance the production capacity, widen their applications, reduce their average formulation cost, boost the life assessment cycle, and many more. The biopolymers synthesized their number of different services in medicine, packaging, automotive coatings, households, etc., which makes the food waste valorization an ideal field of research and suggests the need for extensive production potential.
