Circularity. Construction cannot ignore it. The national policy is to achieve a fully circular construction economy by 2050. By 2030 (so less than 8 years!), 50% of construction must already be circular. But what then is circular? According to the Transition Agenda Circular Construction Economy, it involves the following:
"Circular construction means developing, using and reusing buildings, areas and infrastructure without unnecessarily depleting natural resources, polluting the environment and affecting ecosystems. Building in a way that makes economic sense and contributes to the well-being of people and animals. Here and there, now and later."
