Santiago, Chile

Algramo ("by the gram" in Spanish) operates a refill model in Santiago, Chile, built around reusable packaging with an RFID chip. Customers buy products such as cleaning liquids by the gram into a reusable container; an RFID code on the container grants discounts on future refills, creating a direct financial incentive to bring the same package back repeatedly. The system is offered via in-store dispensing in neighbourhood bodegas and via refill delivery. It expanded to roughly 2,000 bodegas in Santiago, and customer reuse rates rose from around 10% to more than 80% — a rate industry insiders reportedly considered higher than the reuse rate for Coca-Cola's glass bottles. The model attracted Unilever as a partner and investment from Closed Loop Ventures for US expansion. This case strongly supports the closed-loop solution: it shows reuse rates can be driven very high when the return is tied to a concrete, repeated financial incentive (the RFID discount) rather than goodwill — and that the model can work in a developing-market retail context built on small neighbourhood stores.
