Reverse logistics involves the process of planning and controlling the efficient flow of goods from the point of consumption back to the point of origin. It aims to recapture value or ensure proper disposal. Key activities include returning goods to suppliers, reselling, reconditioning, remanufacturing, and recycling. Challenges include meeting consumer needs, managing return volumes and costs, ensuring data and regulatory compliance, and determining the best disposition of returned products. Examples of companies implementing effective reverse logistics include Apple, UPS, H&M, LogiNext, and YRC.
