Johannas Stadsodlingar AB is a company that designs and builds advanced circular food production systems. The company is based in Sollentuna, Sweden. The Swedish company delivers high-quality vegetables to selected restaurants in the Stockholm area and breed fish, although the volumes are not yet large enough for customer delivery. The company's goal is to create sustainable food production methods that address the environmental impact of current production methods, such as long transportation, pollution, overfishing, and water usage. The company believes that mussel farming in the Baltic Sea can be an effective way to lift nutrients back into circular food production. The company was founded by Gabriel von Heijne, Mikael Sellerstrand, Tomas Strandberg, Thomas Bjelkeman-Pettersson, Anke Johanna van Lenteren, William Hamilton, Björn Elfgren. Thomas Bjelkeman-Pettersson has been the CEO since incorporation.
