Production of bioplastic through food waste valorization
Abstract The tremendous amount of food waste from diverse sources is an environmental burden if disposed of inappropriately. Thus, implementation of a biorefinery platform for food waste is an ideal option to pursue (e.g., production of value-added products while reducing the volume of waste). The adoption of such a process is expected to reduce the production cost of biodegradable plastics (e.g., compared to conventional routes of production using overpriced pure substrates (e.g., glucose)). This review focuses on current technologies for the production of polyhydroxyalkanoates (PHA) from food waste. Technical details were also described to offer clear insights into diverse pretreatments for preparation of raw materials for the actual production of bioplastic (from food wastes). In this respect, particular attention was paid to fermentation technologies based on pure and mixed cultures. A clear description on the chemical modification of starch, cellulose, chitin, and caprolactone is also provided with a number of case studies (covering PHA-based products) along with a discussion on the prospects of food waste valorization approaches and their economic/technical viability.

Highlights The tremendous amount of food waste (FW) is produced from diverse sources. To resolve FW problems, implementation of a biorefinery platform for FW is essential. The adoption of such a process can produce value-added products while reducing the waste. This review focuses on current technologies for the production of polyhydroxyalkanoates (PHA). Prospects of FW valorization are discussed along with their economic/technical viability.
