摘要：The total waste generated in Moroccan urban areas is about 5.3 million tons per year, which means 0.76 kg per capita per day, and 1.47 million tons in rural areas, which means 0.28 kg per capita per day. Landfilling is the most popularly used method of waste disposal used today in Morocco, which leads to a considerable energy loss. Converting waste to energy can be considered as a substitution of fossil energy. Solid recovered fuel (SRF) is a high quality alternative to fossil fuel. SRF is mainly composed of fractions with high calorific value which is produced from municipal solid waste including paper, wood, textiles and plastic. SRF is used in cement plant or factories which use fossil energy. This study is concerned with the count and inventory of fuels existing in household waste in BeniMellal city, and this in order to encourage development of energetic valorization of solid waste. The methodology used in this study is based on the MODECOM approach with characterization of 10% of waste produced in 9 sectors per day. The unloading of trucks is followed by the quartering operation, we take 10% per tour and then the sample is transferred to the sorting site. Before the sorting operation comes the screening and sorting process which distinguishes three fractions distribution size: less than 80 mm, between 80 and 250 mm, and more than 250 mm. The first category (less than 80 mm) is not sorted since it‟s composed essentially of organic materials, while sorting the other categories shows that they contain combustible materials at the rate of 42.2% and 10.4 % for the categories „‟between 80 and 250 mm” and “more than 250 mm‟‟ in a successive manner. The results of this study encourage the production of SRF as a substitute to fuel energy or to produce energy.
