Results show that, subject to the uptake of best available technologies, recycling and preparing for reuse are preferred over incineration and landfilling for most of the individual material fractions of CDW because of the associated environmental benefits. However, this shift comes with increased costs for most material fractions (while indicating positive societal gains when internalising externalities). The study further estimates the potential for recycling and preparing for reuse for each individual material fraction of CDW, indicating that 83% of CDW can potentially be sent for preparing for reuse and recycling (of which potentially 16% for preparing for reuse).

The findings of the study can help both public and private actors in cities and regions which are looking to make data-driven and science-based decisions regarding preparation of CDW for re-use and recycling. These findings can help cities and regions, especially those interested in creating re-use platforms for secondary construction materials, in all three phases of CSS Deployment (i.e.: Map, Design, Implement). Specifically, these findings can help with 'Analysing the metabolism of the territory' (thanks to its material flow analysis of different regions of Europe). Furthermore, it can be helpful in 'Analysing potential stakeholders', 'Identifying intervention areas and building a CSS case', as well as ' Preparing for adoption and financing' (thanks to the financial cost analysis of different treatment methods).
