The Province of Noord-Holland initiated the Circular Deal for Secondary Construction Materials together with Circular Westfriesland in 2024. 

The aim is to boost circular construction in Noord-Holland, use fewer raw materials and thus contribute to the region's objective of switching to a fully circular economy by 2050 and reducing the use of primary raw materials by 50% in 2030.

The deal stipulates that all Participating Parties will:

• apply circular harvesting as standard;
• where possible, disclose how much released material has been processed in a circular manner and by what means;
• share knowledge and collaborate on creating new circular chains and identifying and linking up existing chains, platforms and circular raw material hubs.
