Depending on the plants and clusters chosen, Polydome systems can be entirely zero-waste. Inedible plant waste is reused as mulch, compost, and fish feed, while animal waste is used as natural fertilizer. Furthermore, mushroom cultivation, chickens and composing provide the high levels of carbon dioxide that plants thrive on, rather than generators or fossil fuel combustion.
To further maximize productivity, the system also uses stacked hydroponic crops. High profit crops such as strawberries and lettuces are suspended above soil crops, quickly growing in a hydroponic solution. This solution is loaded with nutrients from the wastewater of the Polydome’s fish aquaculture system.
Except suggests that their advanced greenhouse design could be coupled with restaurants, supermarkets and other food vendors. But as BrightFarms has demonstrated, a greenhouse like this could be planted atop any building, brightening the prospects of this concept reaching fruition.
