Conference Circular@WUR: Living within planetary boundaries

General introduction to conference

A transition towards a circular bio-based and climate smart society is the answer to many of the societal challenges we are facing today. Circular systems in the green and in the blue domain will close water, nutrient and carbon cycles and from this, minimize resource losses and climate change effects, and hence assure that society can live within the planetary boundaries.
