This online visualization was developed in 2014 by Elioth, to popularize the concept of urban metabolism for policymakers, project leaders and citizens, by showing how energy, material and water flows are set in motion to support the life of the city : how much electricity, gas, oil, heat, consumer goods, food, and water enter Paris each year? Does the city export more goods than waste? How dependent is the city from energy imports? Is self-sufficiency possible for such a big city ?
Designed and implemented for the City of Paris “Urban Metabolism Optimization” call for projects, the website presents more than 40 local projects, depicting examples of concrete, effective and already operating solutions of the much talked about circular economy (http://metabolisme.paris.fr/#p): how could we reuse materials like granite pavements from demolitions instead of importing new ones? How is the sand of “Paris Plage” recycled each year? How could waste be turned into energy or reusable materials?
