Environmental impact assessment of construction waste recycling versus disposal scenarios using an LCA-BIM tool during the design stage

The scientific community has revealed the environmental benefits of recycling construction waste (CW) versus its disposal, and its contribution to circularity. The Life Cycle Assessment (LCA) method enables the environmental impact of CW management to be quantified and facilitates the comparison of...
