Structured data for circular construction

The construction industry needs to drastically reduce its environmental footprint through the transition to a circular economy. The central tool here is material passports, which provide digital information on the origin and recycling potential of building materials. Despite technical advances, however, research remains fragmented, as the link between data quality and practical circularity strategies such as reuse is often missing. This unsettles decision-makers and hinders nationwide deployment. The study "Evaluating material pass-ports for circularity in the construction industry" by Chinese academics closes this gap through a systematic analysis of literature and case studies. The aim is to develop a stand-ardised data structure that defines the necessary depth of information for a sustainable circular system.
