Vegetables and fish from the roof
Growing vegetables on rooftops is already known. But growing vegetables and fish on a rooftop is new. The German company Frisch vom Dach is planning to exploit a roof on a old malthouse in Berlin. Currently the company already placed an shipping container with an integrated fish tank and an attached greenhouse, this container version operates on a closed water cycle whereby fish waste fertilizes the plants, and the plants purify the water. See the initiative here.
