“…Indeed, in our test conditions, 10 gCOD of propionate per kilogram of medium at a moisture content of 82% corresponded to about 8 g L À1 of propionate in the liquid phase. This value is close to the inhibitory concentration normally encountered (Aguilar et al, 1995;Le Hyaric et al, 2010;Gourdon and Vermande, 1987).…”

“…Le procédé est bénéfique pour l'environnement et offre de nombreux avantages (Nelson et al, 2002;Sakar et al, 2009). Il permet de produire du biogaz combustible, une énergie renouvelable, à partir de la matière organique (Le Hyaric et al, 2010 ;Kalloum et al, 2011). Le recyclage de la matière organique des déchets réduit considérablement les émissions des gaz à effet de serre et la contamination des eaux de surface et souterraine (Romano et al, 2006).…”

REMERCIEMENTS Nous remercions le CRSBAN (UEMOA) et le CIOSPB pour leur appui financier dans la conduite des travaux de recherche. RESUMELa gestion des déchets municipaux est devenue une préoccupation majeure dans les pays en développement, due au manque de politique et de stratégie adaptées. L'étude réalisée a porté sur la valorisation biotechnologique de la fraction biodégradable des déchets au Burkina Faso. Une analyse physico-chimique des déchets échantillonnés dans trois (3) centres de précollecte de déchets municipaux de Ouagadougou a été réalisée. L'influence du type d'inoculum (eaux usées, bouse bovine, flux de broyat de termites et une mixture de ces 3 inocula) et de la charge en substrat (déchets organiques) a été évaluée au cours d'essais de fermentation méthanique. Les résultats obtenus ont montré que les déchets organiques municipaux constituent un substrat de prédilection pour la méthanisation avec un ratio C/N de 31,65. Les essais de fermentation ont permis de noter que la bouse bovine comme inoculum avec une charge en déchets municipaux de 2% donnait la meilleure production de biométhane (297,65 l CH 4 / Kg MSV). Il ressort de cette étude que les déchets municipaux peuvent être traités par la voie de la biométhanisation car présentant un potentiel de bioconversion intéressant. © 2015 International Formulae Group.

Optimization of biomethane production from municipal solid organic wastes ABSTRACTMunicipal solid organic wastes management became a major preoccupation. The achieved study focuses the biotechnological valorization of the biodegradable fraction of solid organic wastes in Burkina Faso.M. NIKIEMA et al. / Int. J. Biol. Chem. Sci. 9(5): 2743-2756, 2015 2744 Physicochemical characterization analysis of solid wastes sampled in 03 Ouagadougou's centers of municipal wastes deposits was achieved. The influence of inoculum source (wastewater, bovine dung, termites' homogenate and mixture) and substrate concentration (municipal solid waste) were evaluated during biomethane production tests. Results showed that organic fraction of solid wastes represent a source of predilection for methanization with 31.65 C/N cow. Fermentation tests showed that bovine dung used as inoculum in 2% of municipal solid waste gave the highest rate of biomethane production (297.65 l CH 4 / Kg vs). The results demonstrate that municipal wastes can be valorized by biomethanization way because presenting interesting bioconversion potential.

“…Compared to the large number of studies focused on the recovery potential of material and energy from both the wastewater and biological sludge line, a rather limited number of researchers have investigated the potential of recovering the energy and material content of the solid residues from wastewater pre-treatment, that is, from the screening units. Some attempts can be found in the literature, mainly focused on screenings components (Le Hyaric et al, 2009), elemental composition (Cadavid-Rodriguez and Horan, 2012) and valorisation through anaerobic digestion (Cadavid-Rodriguez and Horan, 2012, 2013; Le Hyaric et al, 2010). The quantitative characterisation of screenings from three WWTPs located in the southern part of France found that the average annual per capita production, expressed as kg per year per Inhabitants Equivalent (kg (year IE) −1 ) varied over a broad range of values, for example 0.53 and 3.49 kg (year IE) −1 , such a variability being dictated by both meteorological conditions and sewage system characteristics.…”

Valorisation of residues from municipal wastewater sieving through anaerobic (co-)digestion with biological sludge

The Circular and Green Economy principles is inspiring new approaches to municipal wastewater treatment plants (MWWTPs) design and operation. Recently, an ever-growing interest is devoted to exploring the alternatives for switching the WWTPs from being able to ‘simply’ removing contaminants from water to biorefinery-like plants where energy and material can be recovered. In this perspective, both wastewater and residues from process can be valorised for recovering nutrients (N and P), producing value added products (i.e. biopolymers), energy vectors and biofuels (i.e. bio-H2, bio-CH4 and bioethanol). As an additional benefit, changing the approach for WWTPs design and operation will decrease the overall amount of landfilled residues. In this context, the present research is aimed at evaluating the CH4 production potential of MWW screening units’ residues. While such a stream is typically landfilled, the expected progressive increase of biodegradable matter content due to the ban on single-use plastic along with the boost of bioplastics makes the investigation of different biochemical valorisation routes more and more interesting from an environmental and economical perspective. Thus, a full-scale data collection campaign was performed to gain information on screening residues amount and properties and to analyse the relationship with influent flowrate. The most relevant residue properties were measured, and lab-scale tests were carried out to evaluate the bio-CH4 potential.
