Due to globalization, the food value chain has expanded significantly, introducing unique challenges. These include: the surplus of food in developed countries, the lack of sufficient food in other countries, intense resource utilization to produce commercial products, and the burden of waste management. The goal of this thesis is to review the present work addressing these topics. Food sustainability, a concept including concepts related to the affordability, environmental impact, and the social needs surrounding food products, has been a major goal across fields. In this thesis I will review some of the diverse contributions of these different efforts, including food processing, waste management, packaging and food alternatives, and I will discuss some of the limitations and challenges each of these methods.
