Circular Economy

In a circular economy, material cycles are closed as much as possible.

Circular economy: Using resources sustainably and safely

Already in the 1960s, economists developed the model of a circular economy model. It aims to optimize the utility value of resources along the entire value chain and to close material cycles.

In 2019, the European Commission confirmed and updated its 2015 Circular Economy Action Plan. The German government supports these international efforts with its sustainability strategy and the resource efficiency program.

The Bundesanstalt für Materialforschung und -prüfung (BAM) is involved in these activities in many ways: We conduct research on the circular economy in the field of process and product safety as well as environmental safety. In particular, we focus on resource efficiency by developing new processes for extracting of valuable resources from waste and for the recycling of mass residues.

We analyze the durability and ageing behavior of plastics and investigate the environmental compatibility and durability of various products and materials, e.g. innovative building products made from waste.

BAM is also active in national and international committees for standardization and regulation in the field of circular economy and promotes the exchange of knowledge between research and industry.

In this way, we make an important contribution to the transformation of the German and European economy towards a circular economy.
