Closed-Loop Supply Chain (CLSC) Model

A Closed-Loop Supply Chain (CLSC) is a model where the product lifecycle includes a return path, incorporating reverse logistics to collect used products from consumers. These returned products are then sorted, refurbished, or recycled back into the production cycle rather than being discarded.

Unlike traditional linear supply chains that follow a 'take, make, dispose' path, CLSCs actively integrate reverse logistics to recover value from end-of-life products. This means the supply chain extends beyond the point of sale to include collection, processing, and reintegration of materials into new products.

Companies like Patagonia, Dell, and Apple have implemented elements of closed-loop supply chains through product take-back, refurbishment, and recycling programs. These models are increasingly adopted as businesses align with circular economy principles and face regulatory pressure to reduce waste.

Reverse logistics in a CLSC refers to the processes involved in moving used or end-of-life products from the consumer back to the manufacturer or processor. This includes collection, transportation, sorting, and deciding whether products should be refurbished, remanufactured, or broken down for raw material recovery.
