Abstract
Waste management is currently at a critical stage. Globally, it has been highlighted that food waste is a potential resource for the production of biofuels and value-added chemicals. However, there remains the crucial question from industrialists and investors of whether to recover energy, value-added chemicals, or both from food waste. Additionally, the selection of robust and economic processes with environmental sustainability is another major concern. Techno-economic analysis is a deciding factor for process and product selection. It also adds to environmental sustainability by minimizing the generated process waste. This chapter deals with various food waste valorization routes, their techno-economic analysis in a biorefinery approach. Furthermore, this chapter discusses technical challenges, factors associated with commercial scale-up, and the development of cost-competitive biorefineries. These are accompanied by case studies on the techno-economic evaluation, process strategy, and cost estimation concerning both energy and value-added chemical extraction from food waste.
