By way of introduction: What is Circular Economy?

What exactly is meant by circular economy? And what is the significance of the concept for companies? Our articles and podcasts introducing the Circular Economy explain what’s behind it.

Our definition

The concept of circular economy describes a sustainable economic system in which thought and action are taken in cycles that are as closed as possible in order to secure the economic and social benefits of products, components and materials in the long term while respecting the ecological limits of our planet.

Circular economy thus contrasts with the currently dominant “linear” economic system, in which value creation ends abruptly after a short chain of raw material extraction, processing and consumption with often inadequate disposal, landfilling or purely energy recovery.(continue to article)
