A blockchain-based approach for food surplus management

Abstract

Food surplus recovery is one of the priorities of modern society. Mass distribution allows one to reserve goods unsuitable for selling for organisations able to distribute them to people in need. This work contributes to this direction by considering a reward programme for donors. A methodology for supporting the cycle of the reallocation of the food surplus to people in need usingblockchain technology to support the traceability of the flows and to allow the exact evaluation of the rewards to be assigned to each retailer is described. A mathematical model is proposed for calculating the reward. An actual application of the methodology is also described.
