“…The choice of methodology and technology for the installation of biogas units in the country could be done on the basis of this unequal relocation. In fact, the exploitation of organic substrates (animal feces and plant residues) in rural areas could be done in small biogas units to satisfy partially, domestic energy needs [11].…”

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 ...

“…One pathway to reach GHG-emission reductions is the increase and further deployment of renewable energy (RE) technologies. These technologies can potentially contribute to an emission reduction compared to fossil energy carriers, with the exact amount being dependent on the specific technology and its associated value chain [3][4][5][6][7]. Currently, bioenergy has the largest share of RE carriers at the global scale [8].…”

“…However, upgrading biogas to biomethane is not always advantageous, since the upgrading process increases costs, energy demand, and material use and, thus, can trigger environmental effects [24]. Furthermore, the methane slip within the biomethane production value chain can negatively impact the ecological balance [4,25].…”

Biogas Upgrading: A Review of National Biomethane Strategies and Support Policies in Selected Countries

Bioenergy contributes significantly towards the share of renewable energies, in Europe and worldwide. Besides solid and liquid biofuels, gaseous biofuels, such as biogas or upgraded biogas (biomethane), are an established renewable fuel in Europe. Although many studies consider biomethane technologies, feedstock potentials, or sustainability issues, the literature on the required legislative framework for market introduction is limited. Therefore, this research aims at identifying the market and legislative framework conditions in the three leading biomethane markets in Europe and compare them to the framework conditions of the top six non-European biomethane markets. This study shows the global status and national differences in promoting this renewable energy carrier. For the cross-country comparison, a systematic and iterative literature review is conducted. The results show the top three European biomethane markets (Germany, United Kingdom, Sweden) and the six non-European biomethane markets (Brazil, Canada, China, Japan, South Korea, and the United States of America), pursuing different promotion approaches and framework conditions. Noteworthy cross-national findings are the role of state-level incentives, the tendency to utilise biomethane as vehicular fuel and the focus on residues and waste as feedstock for biomethane production. Presenting a cross-country comparison, this study supports cross-country learning for the promotion of renewable energies like biomethane and gives a pertinent overview of the work.

“…Evangelisti et al (2013) studied the environmental impacts of anaerobic digestion with energy and organic fertilizer production, specific to the Greater London area, UK. In the work of Horschig et al (2016) on estimating biomethane market potential, greenhouse gas (GHG) emissions for farm-fed and waste-fed systems and different applications were quantified so as to establish their relative contribution to meeting UK and German national GHG reduction targets.…”

Mathematical modelling and optimisation at both household and energy supply network levels were developed to study the transformation of the natural gas-based domestic energy supply system with the introduction of biomethane generation, processing and utilisation based on a range of feedstock and conversion technologies. Biomethane processing includes, among other options considered, the conceptual development of a novel approach for upgrading biogas which utilises existing onshore natural gas processing capacity. Four different objective functions were considered for optimisation, representing different economic and environmental propositions, to identify the best path for introducing biomethane with multiple types of feedstock. Applying these objective functions to UK’s domestic energy supply, and assuming a range of subsidies available, it was established that a technically significant displacement of natural gas could be achieved, with displacement capabilities of 48%–72%, and greenhouse gas (GHG) reductions between 64% and 80%. Economically, these ranges of achievement would correspond to various levels of capital investment and economic viability, depending on the objective functions. Those cases leading to a positive net present value (NPV) appeared to heavily rely on subsidies and could run into a significant loss if subsidies were removed in the operational phase. In contrast, optimisation not assuming any subsidies in the first place could lead to a fundamentally economically viable system, but at the cost of a significantly lower level of biomethane penetration compared to the cases assuming subsidies. Overall, the results have indicated the importance of carefully selecting optimisation objectives, and revealed the potential consequences of adopting financial subsidies in developing the biomethane infrastructure
