What is Whey

The environmental issues and the projected world population increase have brought into light many different terms and concepts. For over 20 years, sustainability attracts the main focus of most researchers; however, recently the concept of circular economy (CE) is considered to be its successor. CE is based on a closed loop supply chain, where waste is minimized and reintroduced into the supply chain, thus requiring a systemic change. In the agri-food sector, the CE principles have many possible applications. This chapter provides a CE perspective for the dairy supply chain by identifying and analyzing the associated technologies and strategies through a literature review taxonomy based on the related stage of the supply chain.
