Blockchain in the reverse agrochemical supply chain: a systematic mapping study

A product supply chain represents the end-to-end path from a factory to the final consumer. Specific chemical packaging unsuitable for use must return to the manufacturer for disposal or recycling. Agrochemical products appear in this scope. Disruptive technologies are being employed to identify the trajectories of these products. Blockchain appears as one of the most innovative. However, no literature reviews focus on this joint combination of blockchain for agrochemical products. This article presents a systematic literature review. We conducted a systematic literature review to analyse academic articles between 2016 and 2020, and the process resulted in a total of 99 papers analysed. We summarise our contributions as two-fold: 1) an analysis of the state-of-the-art agrochemical products reverse supply chain and the use of blockchain, highlighting challenges and trends; 2) a novel taxonomy to support researchers, government, and retail to address blockchain with agrochemicals.
