As global supply chains transition towards sustainability, Decathlon faces significant challenges in optimizing Circular Economy (CE) strategies due to logistical inefficiencies, cost barriers, and limited consumer adoption.
Although Decathlon has implemented initiatives such as product repair, rental, refurbishment, and reverse logistics, fully leveraging Industry 4.0 technologies - including IoT, AI, blockchain, and digital twins - is necessary to maximize circularity, reduce CO2 emissions, and streamline operations.

This case study investigates the rationale and potential impact of integrating Industry 4.0 into Decathlon's circular economy model to address key challenges and enhance efficiency and sustainability.
