Stakeholder perceptions on implementing design for disassembly and standardisation for heterogeneous construction components.

Abstract

The reuse of construction components is considered as a higher value process in a Circular Economy (CE) than recycling. However, this is not yet widely adopted as many barriers still prevent the successful integration of the concept. The ISO20887 standard advocates that the implementation of construction standards will benefit circular reuse. Yet, these standards still need to be developed. To better understand the views of the construction sector, a survey was sent to the network of the Green Deal on Circular Construction (GDCC), led by Circular Flanders. The survey (number of recipients = 629, response rate = 16%) investigates the current implementation of Design for Disassembly and the reuse of construction components. Additionally, it investigates the respondents' view on how a further morphological standardisation of components and connections, as well as standardisation of procedures can facilitate this reuse of construction components. The result is a concrete set of action points and corresponding actors who need to take responsibility. The stakeholders point out that there is no legal framework for component reuse. Yet, this framework can only be created through their largescale cooperation to create the needed construction standards that will truly enable the circular reuse of components.
