circular economy

Circular infrastructures: Substitution or addition?

Infrastructures are the invisible base on which all other structure is built. Like the roots of a tree their form does not predetermine how the tree looks like, which shape the leafs take and the color of the branches. Instead, there is a back and forth between the roots and the visible parts of the tree, as there is a mutual adaptation of all parts of the organism. However, knowing only abut the roots we can derive certain features of the tree, such as its size and probably more, if we are a biologist familiar with the movements of substances from the roots through the other parts of the tree.
