Introduction: Coffee Collector

Picture of Coffee Collector

Cafes and restaurants can store their coffee grounds so compost can be made out of it.
This coffee collector has been designed to prevent mould on the (wet) coffee grounds.

Restaurant personnel can empty the content of their portafilter in this box or they can fill it with the grounds from their coffee machines.

This instructable is part of a system called Coffee Cycle:

This instructable is part of a larger system called Coffee Cycle.

Coffee Cycle: Used coffee grounds are collected from cafés and restaurants in the neighbourhood with a modified bicycle. These grounds serve as a compost material to grow plants. The coffee grounds are also used to create the biodegradable flower pots which are then given back to the participating restaurants and cafes.
