Despite Germany's Circular Economy and Waste Management Act "Kreislaufwirtschafts- und Abfallgesetz" of 1996, the country's economy remains essentially linear. To transition from this status quo and lead the way towards a genuinely circular and resource-efficient economy, the development of a National Circular Economy Strategy (Nationale Kreislaufwirtschaftsstrategie) (NKWS) is now in progress. The project provides scientific support to the development of this strategy, as much as to the related debate.
