Abstract
Construction and demolition (C&D) waste generated in the finishing stage of a construction project represents a large portion of the total waste generated on a construction site. Most of that waste can be recycled and reused on site. However, recycling actions on construction sites are not routinely used due to the difficulty to identify, separate and sort waste. Knowing the exact C&D waste quantity and quality per stage is essential for its technical and economic reuse. This case study presents a C&D waste gravimetric composition from the final finishing stage of a horizontal residential condominium construction. The results confirmed that 92% of the C&D waste from the final finishing stage could be recycled. The gravimetric composition showed that 39.13% of it was wood; 23.19% was plastic, paper and metal; 16.09% was gypsum and plaster; 12.99% was demolition waste (concrete, mortar, ceramic, etc.); 8.38% was contaminated waste and 0.22% was wire. The quantity results demonstrated a waste generation of 0.58m3/house or 0.012m3/m2 built area. The index obtained to the final fine finishing was 0.46 m3/house or 0.0098 m3/m2 and at the stage of coating with mortar and plaster was 1.11 m3/house or 0.0237 m3/m2.
