“…This volume also depends on the period between two emptying, the sludge accumulation rate, and the sludge occupation rate, which is not only 50% of the useful volume of the pit at the time of emptying but also on [6]. According to Coulibaly et al [7], the specific production that corresponds to the quantity of sludge produced per inhabitant and per day is equal to 0.4 liters per day and per inhabitant. The retention time of sludge inside the pits is estimated at 2.5 to 3 years for a more efficient biological activity [8].…”

In developing countries, in general, especially in universities, the management of wastewater and excreta remains one of the major concerns. This uncontrolled practice can have negative im-pacts on the environment such as deforestation and global warming. The recovery of domestic wastewater through the production of biogas (methanization) is beneficial both on the environmental level and on the energy level (electricity, heat) and social, especially in universities where the increase of the students is accompanied by growth in energy consumption. This article delves into the physicochemical and biological processes involved in wastewater treatment, while also making predictions about the behavior of various variables such as methane, nitrogen, acetogenic microorganisms, and methanogenic biomasses. This approach allows knowing the variation of the biomass according to the type of bacteria. Indeed, it shows the relation, which exists between the biomass and the organic load. It is firstly noted in the results that the mean value of the biomass of acidogenesis and that of the biomass of methanogenesis are approximately equal to 0.67 d−1. Secondly, the nitric acid concentration is around 47.5 mgN/l/h and that of the viscosity is estimated to 0.046 Pa.s. Afterward, the temperature and the pH favor the activity of anaerobic bacteria. We finally conclude that an experimental device of 71m3 intended for the accumulation of sludge will be designed and built.

“…These farming activities generate large quantities of waste composed mainly of organic residues, of which the mismanagement constitutes a proven source of pollution of the components of the environment [4]. A study carried out on the method of managing agropastoral waste in the Sassandra watershed revealed that this waste was mostly incinerated in the open air or used to meet the energy needs of the populations [5]. However, incineration could lead to bush fires that would devastate surrounding plantations, plant cover as well as biodiversity.…”

The valorization of crop residues could constitute an energy source (biogas) allowing to reduce the energy needs of populations in agricultural regions, improve their living conditions and slow down deforestation as well as greenhouse gas emissions. This work aims to determine the typology of agricultural waste in the departments of Soubré, Sassandra, Daloa and Issia, to determine the number of residues generated in these departments, and to assess the biogas potential of these departments said residues. Field observations were made to identify the different types of waste, then, based on agricultural statistical data from the Ministry of Agriculture and biogas productivity indexes, the quantities of agricultural residues and biogas were estimated. Agricultural residues consist of pods (50%), stalks (19%), cobs (3%), Straws (8%), stalks (2%), shells (9%), fibers (7%), husks (1%), and bunches (1%). In addition, these localities have 465266.3 t of pods, 173583.2 t of stalks, 84280.0 t of shells, 75,857 t of straws, 12,000 t of husks, 10,987 t of bunches and 6793.0 t of fibers. The departments of Soubré, Sassandra, Daloa and Issia contain a total potential energy of 235.87 × 10 6 m 3 of biogas. However, this is unevenly distributed among the localities. The volume of biogas recorded is higher in the department of Soubré (74.91 × 10 6 m 3 ) which is followed respectively by the departments of Daloa (62.27 × 10 6 m 3 ), Issia (52.77 × 10 6 m 3 and Sassandra (45.93 × 10 6 m 3 ). The departments of Soubré, Sassandra, Daloa and Issia have a very large potential for the production of agricultural residues that
