house gas emissions. In addition Morocco’s economy is heavily dependent on<br />
agricultural and animal husbandry practices therefore the increased amounts <strong>of</strong> green<br />
waste and animal manure that is produced, raise a point <strong>of</strong> concern with respect to the<br />
management and treatment <strong>of</strong> these wastes.<br />
The experimental composting trials developped during the 3 rd Task <strong>of</strong> <strong>MOROCOMP</strong><br />
project aim to present the compost quality characteristics and the effects <strong>of</strong> the unit’s<br />
operational conditions on the efficiency <strong>of</strong> the process. Therefore for each <strong>of</strong> the<br />
composting trials that have been developed a series <strong>of</strong> steps have been performed.<br />
4. Methodology and experimental procedures<br />
The development <strong>of</strong> aerobic composting processes using sludge, other BOW (green<br />
waste and manure) and effective additives (zeolite, perlite) were studied in this<br />
programme. To justify the successful implementation <strong>of</strong> the development <strong>of</strong> effective<br />
composting and co-composting processes and optimisation <strong>of</strong> the system various<br />
experiments were carried out. These experiments were focused on the compost quality<br />
characterization and on the effects <strong>of</strong> the operational conditions on the efficiency <strong>of</strong><br />
the process, as well as on the end product quality.<br />
The achieved quality <strong>of</strong> the end product was the criterion for evaluating the<br />
composting process. For this purpose complete physicochemical analysis <strong>of</strong> the end<br />
product resulted from extented series <strong>of</strong> experiments that took place. The parameters<br />
that needed to be measured were the total carbon, total nitrogen, total and available<br />
phosphorous, total water content, pH, total and available potassium, sodium,<br />
magnesium, manganese and calcium, heavy metals content and speciation, biological<br />
and microbiological activity analyses.<br />
Several composting trials have been performed throughout the duration <strong>of</strong> the 3 rd Task<br />
<strong>of</strong> the <strong>MOROCOMP</strong> project using the composting system that has been designed and<br />
constructed in Task 2. Initially the raw materials that had been used for composting<br />
were selected and analysed. These materials included primary sewage sludge from the<br />
city <strong>of</strong> El Jadida, sugar beet leaves, straw residues, sheep and cow manures in various<br />
ratios.<br />
