“…Alongside the Internet of things, other technologies, such as additive manufacturing, artificial intelligence, and machine learning, can play a pivotal role in enhancing sustainable and circular practices. 3D food printing, for instance, can contribute to reducing food waste through the usage of food by-products and eco-friendly foods (Burke-Shyne et al, 2021), while machine learning can instead enable dynamic pricing, a promising strategy for retailers wishing to increase their revenues and reduce food waste (Scholz and Kulko, 2021). In this regard, De Bernardi and Azucar (2020) provided the case example of a food start-up that uses a machine-learning pricing engine to price products in real time based on a series of dynamic variables that include the expiration date, shelf capacity, regional factors, brand strength, and on-shelf competition.…”
