The project has been initiated by HvA with the objective to identify opportunities for wood reuse through the use of advanced digital production technologies, and develop related implementation strategies for public organisations, in particular housing corporations and municipalities. Strategies include concrete proposals on how to: a) collect and process wood waste from residential buildings; b) add value to reclaimed wood by means of digital production; c) increase tenant involvement and acceptance for waste wood collection and circular reuse; d) create impactful applications for a circular economy.

The project explores the availability and nature of wood waste from residential buildings, and identifies opportunities for reuse. Evidence from preceding projects shows that digital production enables turning urban waste into meaningful circular products, and facilitates the (local) fabrication of unique prototypes and full scale applications, which can become tangible demonstrations of circularity for public organisations.

Previous projects developed at HvA and TUD (Fig. 1 and 2) represent the basis of this research, which is carried out in four work packages. The first identifies the nature of residential wood waste (volume, type, application) from past case projects of housing corporations Ymere and Rochdale. Their upcoming renovation plans are also evaluated, to identify resources and hotspots for future implementations. Finally, the development of a KPI framework helps determine the impact of specific applications. The second work package explores what applications can be conceived, given the available wood and digital production tools. In the third work package case studies are carried out for actual projects of the housing corporations, showing the potential of digital production and providing insights on the viability of concrete applications. Physical prototypes are used as conversation pieces to involve tenants and increase their acceptance for circular applications. In the fourth work package all findings are combined in a set of implementation strategies.

The project explores biomimetic architecture in the times of the 4th industrial revolution as an architectural intervention in a building from the 2nd industrial era. The main architectural intervention is a new atrium for the historic building. The computational design relies on biomimetic simulations, structural and robotic path optimizations. By using smaller linear circular wood elements that are robotically glued and milled into larger curvilinear elements connected to topologically optimized 3D printed metal nodes the project not only addresses the current quest for circularity but also takes advantage of the most recent robotic technology developed at TU Delft.
