Chicago – An abandoned factory is being used as a self-sustaining farm for small food businesses called The Plant.
The farm aims to be net zero energy and net zero waste by 2015, and runs on a closed-loop system, in which all of its output is another component’s input.
The farm grows plants and vegetables using waste from fish tanks. In future, other waste will be fed into an anaerobic digester, which is due to be completed by summer 2013. The digester will power a turbine generator, creating electricity to power lamps to give plants the light they need to grow.
This is a great example of a closed-loop system. For more on this idea read the Closed-Loop-Homes section of our Future Family macrotrend. For a specific example, read our Innovate article on the Philips Microbial Home.
