The company Canavero Marco, now projected into a system of technological agriculture, Agriculture 4.0, has developed a technological greenhouse equipped with a completely bio-sustainable aquaponics system. There are two breeding tanks for fish and crustaceans that are the beating heart of the system, as fish production provides nourishment for vegetable plants, leafy vegetables, aromatic plants, medicinal plants and even saffron for inflorescence through the nitrogen-rich wastewater on which the green plants feed.
