Abstract

Berkeley rapid composting is one of the most effective ways of recovering organic waste, producing a final composting product in a very short time compared with other types of composting. For the first time in Morocco, and more specifically in Béni Mellal, this rapid composting process was applied to casing waste (50%) mixed with a manure fraction (50%) in order to study its qualitative and quantitative feasibility. The results of this experiment showed that the C/N ratio of the compost reached 21.3 and the quantitative efficiency did not exceed 47.9%. The aim of this work is to study the influence of the mixed fraction percentages and the effect of grinding the casings on the feasibility of rapid composting. The results showed that the economic efficiency of composting surpassed 60% when the casing fraction was more than 50% of the mixture and reached 65% when the casing waste was shredded.
