The document discusses the scale of the waste problem globally, with only 0.6 billion tonnes of waste being recycled out of 2.2 billion tonnes generated. It outlines the principles of a circular economy in keeping resources in use for as long as possible and extracting maximum value. Transitioning to a circular model could reduce industrial emissions by over half by 2050 and cut EU carbon emissions by 450 million tonnes by 2030. Various business models, processes, and technologies are enabling the circular economy transition.
