Fish waste in the form of ammonia, is turned into nitrite then nitrates by bacteria in water. When filtered through a plant bed the plants clean the water for the fish/livestock to live in. The system here is a 225L fish tank and will grow approximately ten 15cm plants per week, on a four-week cycle. Because the plants dont grow in soil the system can utilize the vertical in cities space to grow food.
This project proposes that the discarded waste product from the existing aquarium service infrastructure should be used to grow food. this system is a prototype working towards giving office workers a free and sustainable lunch once a month.
