Urban NEXUS Case Story: The Hammarby District
A Closed-loop System Integrating Water, Waste and EnergyCompleted in 2018, the Hammarby district in Stockholm was built in line with the closed-loop urban metabolism concept. The district has its own integrated water-energy-transport system that processes sewage sludge and compost for use as fertilizer and extracts energy for local heating and public transport from waste incineration and water treatment.
The Urban NEXUS project 2013-2014 was funded by the Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ) GmbH on behalf of the German Federal Ministry for Economic Cooperation and Development (BMZ). ICLEI, as implementing partner of the Urban NEXUS project, is responsible for the content of this case story.
