The project :metabolon has created an innovation site with a focus on research, education and circular economy on the Leppe landfill in Lindlar, Germany, where a competence centre for circular economy, resource management as well as environmental and landfill technologies has been established.

The landfill has been made accessible to the public so that circular economy and modern waste management can be experienced by everyone. The site also provides a viewing platform on the top of the landfill and a multitude of information options and recreational activities for junior as well as senior visitors. It is a place to learn about circular economy and create the future together.
