This startup uses fish poop to grow fresh leafy greens inside a Brooklyn warehouse
In a year, the company estimates the farm will produce about 50,000 pounds of tilapia and 130,000 pounds of leafy greens, such as chard, kale, mustard greens, and radish greens.

Edenworks is an urban farming startup that will soon grow different varieties of greens inside a 10,000-square-foot Brooklyn warehouse all while raising tilapia and using their waste as fertilizer.
Set to open by the end of 2016, the vertical farm, called Farmstack, will act as a man-made ecosystem and function without natural sunlight.
The fish will be raised in tanks with a special type of bacteria that can turn the fish waste into fertilizer, which will in turn be used to help grow the vegetables with LED lights in trays stacked 20 feet high. The plants will then filter the water, which the team sends back to the fish.
“It’s almost like brewing beer, but we’re fermenting poop into really rich fertilizer, like liquid manure,” Edenworks’ CEO Jason Green tells Tech Insider.
