designer's own words:GrowGreen is a new food waste disposal system for apartments including public and personal bins. Users can buy disposable bins made of eco-friendly, biodegradable material (PLA) which they fill and throw away in the public bins. Disposable bins come in three different shades, each indicating where the recycled waste will go. As they stack in the public in, on the front a metaphoric tree will grow as feedback. Also the neighborhood gets incentives for apartment managing fees.
