Aquaponics

No doubt you’re familiar with aquaculture and probably hydroponics too – but have you heard about aquaponics? Upward Farms recently raised $15 million for scaling its symbiotic agricultural model, in which the nitrogen-rich wastewater from fish tanks is used to fertilise leafy greens. This is a way to mimic what nature does, turning waste from one process into food for another. The jury is still out on whether this can be scaled in a sustainable way. Any intensive agriculture creates unintended and often unwanted impacts. But there are definitely community and environmental benefits from local, circular economy inspired food production.
