Client: Bouwcampus & the Urbanization Alliance
By 2040, 230,000 homes must be built in the Southern Randstad. This task requires enormous quantities of building materials annually, such as concrete and asphalt. At the same time, there is a target to be 100% circular by 2050. Therefore, it is important that homes are built as much as possible with materials that have the lowest possible Environmental Cost Indicator (ECI).
Towards a Circular Raw Materials Cluster
Linking the circular transition challenges and the housing challenge can accelerate and strengthen these challenges. Creating a Circular Raw Materials Cluster (CGC), in which raw materials are processed, developed, and deployed in a circular manner, could potentially play a key role. Furthermore, a CGC offers opportunities for experimentation and innovation. This can take the form of high-quality processing of materials from the Urban Mine, derived from construction, demolition, and renovation waste. It can also facilitate developments and innovation in the concrete, asphalt, and waste industries.
Collaboration between New Economy and Stec Group
New Economy and Stec Group Commissioned by the Bouwcampus and the Versteelijkingsalliantie (Realization Alliance), the project team developed an initial version of a spatial and economic model. The model helps facilitate strategic consideration of the location of future production capacity in the region. This is intended to facilitate circular and industrial symbiosis in the form of a CGC. Three different future perspectives were considered, prioritizing sustainability ambitions. These are based on national objectives such as the Climate Agreement, the Raw Materials Agreement, the Concrete Agreement, and the Circular Construction Economy Transition Agenda. These perspectives can be encouraged by the government and other parties by requiring a low Environmental Cost-of-Cash (ECI) in tenders.
