It won't solve climate change single-handedly, but we'll damned if The GrowUp Box isn't a nifty piece of sustainability worth checking out this summer. Using a technology called "aquaponics", the box creates a (nearly) self-sustaining loop, where nutrient-rich waste water from fish tanks is pumped into the roots of plants. Next, the plants purify the water, which is then pumped back into the tanks. And so on.
The results speak for themselves: using only fish food and the power required to operate the pumps, the GrowUp Box is capable of producing around 100kg of fish and 400kg of salad each year.
