This research work made it possible to study waste deposits suitable for methanisation in the city of Tangier Biogas recovery offers two scenarios: the installation of a cogeneration plant and the production of electricity or the direct use of biogas. From a climatic point of view, electricity production is more favorable since the substitution of electricity generates a maximum reduction of CO2 equivalents. From a financial point of view, the direct valorization of biogas is more economical because it saves costs for a cogeneration plant. The energy recovery of waste is generally justified by the fight against global warming and the promotion of renewable energies.

At present, although there are several studies and waste management strategies at the international echelon, but there is no consensual method for the characterization of waste. Also at the national level reducing the quantities of final waste with the development of recycling branches and made the valuation and reducing pollution linked to the storage and disposal of waste is a regulatory objective, political, economic and priority order for the preservation of the environment.It remains clear that a single parameter is not enough to characterize and describe such heterogeneous and hazardous waste such as those in our country: with more than 60% organic matter, a high humidity and sometimes containing hospital and / or industrial waste. The different analysis methods followed in this work is devoted to the characterization of Household Garbage and assimilated. The particularity of the sampling approach was highlighted on the landfill site based on plans of town-collect and to provide the maximum information on the Household Waste of Tangier. later laboratory work was carried out.The study of the composition of the waste is an essential step for a sound management for a number of reasons,including the need to estimate the quantity of material produced, identify their generation source to facilitate the design of equipment and treatment processes, defining the physical, chemical and thermal properties of the waste and to ensure compliance with laws and regulations.

An urgent demand for the existing landfill Tangier to host household and industrial waste in the city until 2016 Expected opening of future landfill dates. This application requires to study at the exploitation and especially the compaction mode to estimate the remaining life of the landfill and to propose improvements to withstand up to 2016. This article presents an overview of the physical characteristics of household and similar waste of the Tangier landfill, especially composition, granulometry and moisture. The aim of this work is to know whether the mode of compaction used is valid for the landfill persists until 2016 if not what are the appropriate solutions improvements in this case.
