MOROCOMP project will contribute towards the development of innovative alternatives bytaking advantage of the sludge and the other biodegradable organic wastes, which until now,were not used in agriculture.II- Evaluation of the production of sludge and otherbiodegradable organic waste in MoroccoWhile sludge production is easily quantifiable with respect to available data, the diversity ofthe BOW sources and the scarcity of the relevant official statistics, have obliged us to adopt aparticular work strategy. Thus, the teams involved in the MOROCOMP project, have chosena methodological step which allows, for the first time in Morocco, to establish a quantificationof sludge and of the different BOW sources per type and per region in the country.The methodological approach consists of i) the creation of a BOW resource and sludgeinventory, ii) the quantification of each resource (enquiry, field visit, direct evaluation, websearch, consultation of official archives) and iii) the compilation and synthesis of the resultsobtained per activity sector and per Morocco region.Thus, the five types of sludge and BOW sources that have been listed according to theirimportance in quantity and in quality are as follows:o Sludge from waste water treatment stationso Sludge from the cleaning of sanitary networkso Waste from agricultural and food industrieso Waste and residues from agricultural production.o Residues from timber processing and waste from slaughterhousesThe production of every type of waste (sludge and BOW) was part of a separate evaluation inorder to produce evidence for their potentialities on a regional scale in view of a rationalexploitation by composting. This evaluation required a quantification method adapted to eachtype of biodegradable organic waste.1- Quantification Method adopted according to BOW typeThe annual sludge production at the level of wastewater treatment stations in Morocco wasevaluated based on the following: the waste waters treatment produce the equivalent of 30 to40 grams of dry material (MS)/inhabitant/day in the form of sludge.vi
