This document provides guidance for processes allowing for (raw) materials used to be returned to the economic cycle based on circular design principles. The focus is on open systems that allow for economically interesting alternatives and are not limited to the principle of closed cycles (product to product).
Specific attention is given to renewable materials, where applicable.
The document is structured along the life cycle of the products, starting with the production phase.
Excluded is packaging, which is not considered part of the product end-of-life stage.
