An alternative, given that a breakdown of the waste stream already exists over time, was to analyze each waste stream and to determine the characteristics of a potential composite stream, using a weighted average based on the relative mass of the different wastes produced. This was the approach taken and samples were taken to Labomag laboratory in Casablanca, Morocco for some preliminary analyses. Analyses were done in accordance with the U.S. Composting Council’s Test Methods for the Examination of Composting and Compost (TMECC) procedures (Thompson et al., 2003). The results of the analyses of the waste stream and other raw materials are given in Table 1.
