In recent years many countries and several regions in the United States have passed legislation on banning landfilling of organic waste. It is a well-known fact that organic wastes, including food scraps, generate methane under anaerobic landfill environments and contribute significantly to global warming. As more regions are mandated to follow the landfill ban, there is an increasing demand for alternative technologies for the disposal, treatment and upcycling of food wastes. Disposal and treatment may not result in any value-added products and hence are not the most efficient ways to manage food waste. As food waste has a high energy value due to the presence of organic nutrients, it can be a suitable resource to generate energy, fuels, chemicals, and materials through ‘valorization’technologies. Therefore, to proactively address food waste management issues in the future, this dissertation evaluated three alternative food waste valorization options for institutional (food scraps) and industrial food wastes.
