Evaluation Énergétique Et Environnementale Des Déchets Ménagers De La Wilaya D’ouargla. Cas D'étude Du Centre D'enfouissement Technique De Bamendil Ouargla

Résumé: The purpose of this study is to identify the reality of waste management in the wilaya of Ouargla as part of the implementation of the national integrated program of waste management PROGDEM، and to assess the quantities of waste in the wilaya، and to provision the energy potential obtained with their exploitation، by explaining the methods of treatment and recovery of household waste taking into account their environmental impacts، through the case study of the "Bamendil" technical landfill site. Ouargla. We calculated the difference between the quantities of waste produced in the three communes (Ouargla،Ruwaisat and Sidi Khuwailid) and the quantities received by the center. The difference has been estimated at around 18% for the commune of Ouargla، this value has a significant impact on the environment. We report to the influence of the gases emitted by the ponds on the environment، in particular on the global warming (greenhouse effect)، as well as on the human health، in particular the health workers of the center، . We also calculated the percentage of the center's revenues from recovery and recycling operations، which were considered negligible compared to the expenditure، hence the need for energy recovery of the waste of the center، if by exploiting the gases emitted for produce biogas. We have considered the energy capacities of the center، estimating the quantities of biogas that can be produced and the quantities of energy that can be obtained in the form of electricity or thermal energy، the estimated values are respectively 40389442KWh ، 112080701550 Kcal following the study we explain the processes of production of organic fertilizers (compost).
