After nearly two years of dedication and collaboration between multiple partners across 3 neighbouring countries (The Netherlands, Belgium and Germany), the Interreg NWE project, ASSET (A Spatial Strategy for the EuroDelta: boosting the circular builT environment), has officially reached its conclusion.
Led by the City of Amsterdam, ASSET aims to assess the feasibility of developing a spatial strategy for a circular built environment (CBE) at the EuroDelta scale (megaregion spanning across the Rhine, Meuse, and Scheldt river basins) while exploring the added value of collaboration between participating partners.
The main result of ASSET is a roadmap towards a spatial strategy for a circular built EuroDelta, along with inspiration visions. Another significant milestone of the project is the formation of the EuroDelta Alliance, marked by the signing of a Letter of Intent by the founding partners to continue advancing efforts at the EuroDelta scale.
The development of the inspirational visions was based on a variety of activities, including the following: a policy analysis of stakeholders, a one-week excursion, webinars, a Metrex mini symposium on EU rules, local urban design workshops, analysis of circular best practices, a Circular Design Atlas, and contributions from hundreds of students.
The methodology guiding the process was provided by the Province of South Holland, which had originally developed it to create the first spatial strategy for a circular built region. Building on this methodology, the roadmap was developed to support local workshops focused on testing urban development planning. This roadmap can also be applied in other regions and cities worldwide.
This project, which officially concluded in June 2025, was directly initiated by the METREX SURE Network Group, which has since been renamed the EuroDelta Alliance network group.
