IntroductionAnaerobic digestion is the natural biological process of organic matter's degradation in absence of oxygen (anaerobic). Some of the organic matter is degraded to methane, and another is used by the methanogenic microorganisms for their growth and reproduction. The decomposition is not complete and leaves the "digestate".Naturally, it occurs in some sediments, marshes, rice fields, and in the digestive tract of certain animals: insects (termites) or vertebrates (ruminants). Anaerobic digestion is also a technique artificially applied by men in digester where the process is accelerated and maintained to produce a usable methane (biogas, referred to as biomethane after purification).The great interest of methanisation plants on farms is the diversification of their production, through the generation of renewable energy (from biogas) in the organic amendments' production through optimized treatment of the organic waste from the farm. Anaerobic digestion is particularly interesting in the context of precarious countries, as in the case of Côte d'Ivoire, not only because it contributes to the treatment of fermentable organic residues and to the management of pollution, but also because it offers, through its main products (biogas as a source of energy and solid digestate as an organic soil amendment), solutions and income-generating options. This method of treatment is applicable to a wide range of cellulosic organic wastes, including cow dung, poultry manure, pig manure, human excreta, plant residues, fermentable fractions of household refuse and industrial waste agrifoodstuffs are characterized by their aptitude for recovery by aerobic and anaerobic biological treatments and a relatively rapid decomposition especially in the climates of intertropical countries. Also, these residues contribute to the emission of unpleasant odors, air pollution, pollution of ground and surface waters, and the proliferation of insect vectors of diseases. Anaerobic digestion is therefore an interesting alternative especially for rural areas because of its potential for production from
AbstractAnaerobic digestion is the natural biological process of organic matter's degradation in absence of oxygen (anaerobic). In this work we estimated the potential of biogas production by anaerobic digestion of fermentable residues from agricultural origin in Côte d'Ivoire. To date, no quantitative estimation or physicochemical parameters of agricultural residues have been undertaken on a national scale in Côte d'Ivoire.This work gives an initial contribution to the estimation of biogas production potential by the anaerobic digestion process of agricultural residues. It was developed on the basis of statistical data from FAO (Food and Agriculture Organization of the United Nations) and other structures related to agricultural production.This study revealed that total agricultural residues were estimated to be more than 5.0 × 10 6 tons of organic matter or the equivalent of more than 10 × 10 8 m 3 of methane in terms of potential energy by ...
