Circular Construction Indicator: Assessing Circularity in the Design, Construction, and End-of-Life Phase

The construction industry is responsible for half of the currently excavated amount raw materials. In addition, a quarter all waste in European Union waste. This comprises numerous materials that can still be reused or recycled. Thus, shift to circular sector necessary. To make this shift, it vital enable measurement and progress toward circularity. Therefore, paper investigates available circularity indicators with regard 4 Rs—Reduce, Reuse, Recycle, Recover. Subsequently, comprehensive Circular Construction Indicator framework introduced evaluates project according three typical phases: design, construction, end-of-life. this, new partial assess material scarcity, structural efficiency, service life prediction should help designers consider these aspects already conceptual design stage. Lastly, suggestions further research are defined develop said indicators.
