The city FEEDS the city and FERTILIZES the countryside
Modern technology makes it possible to grow vegetables and fish in closed systems. This means that production can get closer to consumers. We now have the ability to share energy and take advantage of residual flows that were previously classified as waste and were a problem. Food production in closed circular and sustainable food production systems in urban environments has the opportunity to utilize heat and power resources from adjacent businesses. The surplus of, for example, heat that previously cost money to ventilate away, is today an important resource in a circular production model. Urban water and sewerage systems, which are often strained and have problems separating nutrients, which can lead to eutrophication of our seas and watercourses, are now becoming a source of extraction and production of recycled fertilizers. We can in the long run get rid of the use of the unsustainable production of mineral fertilizers. Through controlled and predictable production with the help of AI technology, much of the overproduction that is the source of food waste can be avoided. The city can not only FEED itself with vegetables and fish but can FERTILIZE grain and outdoor food production in the countryside.
