ICA Maxi Supermarket in Solna has installed Swefreens's in-store farm, producing leafy greens and herbs on-site inside the store itself offering customers fresh and hyper-locally produced greens all year round. The climate-smart cultivation system enables energy, water, and nutrients to be recycled and reused in a sustainable manner. The technology that is used is called vertical farming and hydroponic cultivation - a modern and very sustainable way of growing food in which there is no need for using soil and nutrition becomes available for the plants via nutrient-rich irrigation water, which is recycled in a circular system. https://www.mynewsdesk.com/se/swegreen-ab/pressreleases/swegreen-och-ica-maxi-solna-skapar-stockholms-stoersta-butiksodling-3124583 (in swedish)
