Abstract: Construction & Demolition Waste (CDW) is not homogeneous in terms of composition, particle size distribution and porosity. In many Brazilian recycling plants, gypsum and cement asbestos is visually identified without certain diagnose capable to quantify the importance of such secondary components. This paper analyzes some important characteristics of CDW (grain size distribution, composition, density distribution) from different regions in Brazil (states of Sao Paulo, Rio de Janeiro and Alagoas) carried out on samples obtained from a large sampling campaign. Based on these characteristics, a laboratory processing study was done to establish the most efficient hand sorting procedure to be combined with a low-cost recycling plant proposal (without crushing system).
