Abstract
In order to solve the problem of the management of municipal solid waste in Abidjan (Cote d’Ivoire), a sanitary landfill has been designed in Kossihouen. Despite the adverse greenhouse effects of the methane, this gas has a potential of electrical energy. The estimation of methane emissions from the waste can be an economic and useful way for more accurate control and management of waste disposal in Kossihouen. Therefore, conducting this study is essential. Methane emissions were estimated based on the methane generation constant K and the methane generation potential L0 using LandGEM 3.02. The results show that the quantity of methane emissions was 7.97E+07 m3/year. Based on this result, the methane content can generate 10% of total electricity consumed in Abidjan in 2026. This paper could serve as a source of scientific information for decision making on environmental sustainability in waste-to-energy projects in Cote d’Ivoire.

Concerning the value of methane generation potential L0, it strongly depends on the fraction of the landfill waste [15]
Summary
Increasing growth of population and urbanization and subsequent development of industrial units have led to greater production of wastes and pollutants. One of the most commonly used and most flexible models is LandGEM [4] This model that has been developed by the United States Environmental Protection Agency (USEPA), estimates an acceptable quantity of produced methane in landfills over time. It is governed by two main factors, the methane potential (L0) and the decay rate (k) of landfill waste [5]. This model has been considered as an automatic estimation tool for modeling landfill methane emissions from municipal solid waste (MSW) It estimates the volume and composition of the generated methane throughout time because of the degradation of organic matter in the landfill. This model is an important step in developing a landfill project, which allows to estimate the available recoverable quantity of methane as fuel energy over time [4]
