The National Circular Economy Strategy in the Ministry of the Environment and the Raw Materials Strategy in the Ministry of Economic Affairs and Climate Protection: groundbreaking future strategies are the responsibility of different ministries – including the German Sustainability Strategy, which was developed across ministries. We discuss ways out of silo thinking and how a future-oriented and fact-based policy can succeed in politically and socially unstable times.

The construction industry is the most resource- and waste-intensive economic sector in Germany. At the same time, many builders, real estate developers and construction product manufacturers are already demonstrating how much C2C is already being implemented and is possible in the industry today. So the construction industry has arrived in the midst of the transformation, but what happens next? We discuss best practices from the sector, where C2C-inspired construction is already more economical than conventional approaches and what levers are available to accelerate this development on a broad scale.

If Cradle to Cradle and Circular Economy are to become more commonplace in everyday working life, more people need to be competently trained in them. C2C can be integrated into vocational training at many points, regardless of the type of training people choose: in the vocational orientation phase at school, in the training context for skilled workers and also during their studies. We are discussing how we can provide young people with information about various options, get them interested in these topics and motivate them to train or choose a career in the circular economy.
