A growing global population calls for an increasing demand for food production and processing industry associated with it, and consequently generation of large amounts of food waste. This problem is further intensified due to slow progress in the development of effective waste management strategies, and less measure for the proper treatment and disposal of waste. Food waste is a reservoir of complex carbohydrates, proteins, lipids and nutraceuticals and can form the raw materials for commercially important metabolites. The current legislation on food waste treatment prioritises the prevention of waste generation and least emphasises disposal. Recent valorisation studies for food supply chain waste opens avenues to the production of biofuels, enzymes, bioactive compounds, biodegradable plastics and nanoparticles among many other molecules.
