ECOSU

Indonesia’s fast-growing coffee shop sector faces a hidden waste crisis, with millions of milk cartons that are difficult to recycle discarded each year. Limited recycling infrastructure means most are burned or sent to landfill, while environmental responsibility remains a low business priority among small cafés.

Inspired by Indonesia’s local water refill culture born from the absence of a municipal water system Ecosu reimagines milk delivery through a portable, refillable dispensing and cooling system. Designed for pop-up and mobile cafés, Ecosu follows a use-and-return model featuring a dispenser, portable cooling unit, and reusable 3-litre milk jugs. This closed-loop system cuts packaging waste, supports local dairy cooperatives, and encourages a cleaner, more efficient, and community-driven supply chain across Indonesia’s growing café network.
