One of the most important stocks and flows in my country are: Food, building materials, tourists and inner migration, transit of goods and so on. For example most of building materials are imported in the country. They stay in built environment for a long time, but after demolition or disassemble of buildings, renovation of infrastructure or so on steel elements are send/sold as junk to other countries. For the benefit of the country economy it would be an option to have some factories to process junk and produce new building materials or something else made out of steel.
