Scientific Study from the year 2022 in the subject Computer Sciences - Artificial Intelligence, University of Essex (School of Computer Science and Electronic Engineering), language: English, abstract: Food waste is an important social and environmental issue that the current society faces, where one third of the total food produced is wasted or lost every year while more than 820 million people around the world do not have access to adequate food. However, as we move towards a decentralized Web 3.0 enabled smart city, we can utilize cutting edge technologies such as blockchain, artificial intelligence, cloud computing and many more to reduce food waste in different phases of the supply chain. In this book, we introduce FoodSQRBlock and SmartNoshWaste - two blockchain based multi-layered frameworks in the food supply chain utilizing cloud computing, QR code and reinforcement learning to reduce food waste.
