Focus - État du développement de la méthanisation en France [PDF]

Sciences, Eaux & Territoires, 2013
La méthanisation prend de plus en plus d’importance en France. Cependant, ce phénomène étant relativement récent, il est intéressant de voir quels choix de production de biogaz sont faits et comment ce biogaz est valorisé.

Les collectivités : une source de déchets organiques  et une voie de valorisation de la chaleur  pour la méthanisation agricole ?

Sciences, Eaux & Territoires, 2013
Tout projet de méthanisation agricole a besoin de déchets très fermentescibles et doit pouvoir valoriser au mieux la chaleur issue de la cogénération pour améliorer sa rentabilité.

Modeling CO2 capture processes by chemical absorption: The case of biogas treatment [PDF]

E3S Web of Conferences, 2021
Our objective through this work is to purify the biogas produced by a methanisation process in order to be valorized in a cogeneration unit. The studied biogas is mainly composed of methane 60% and carbon dioxide 39%.

Effect of ultrasonic, thermal and ozone pre-treatments on waste activated sludge solubilisation and anaerobic biodegradability [PDF]

, 2006
In order to enhance the efficiency of anaerobic digestion, the effects of ultrasounds, ozonation and thermal pre-treatment have been studied on waste activated sludge.

Biomethanation potential of macroalgae Ulva spp. and Gracilaria spp. and in co-digestion with waste activated sludge [PDF]

, 2012
Biochemical methane potential of four species of Ulva and Gracilaria genus was assessed in batch assays at mesophilic temperature. The results indicate a higher specific methane production (per volatile solids) for one of the Ulva sp. compared with other

Reduction of sludge production from WWTP using thermal pretreatment and enhanced anaerobic methanisation

Water Science and Technology, 2005
The objective of the study presented here was to investigate the performance of an enhanced two-step anaerobic process for the treatment of WWTP sludge. This process was developed to answer the urgent need currently faced by WWTP operators to reduce the production of biosolids, for which disposal pathways are facing increasing difficulties.

Transition énergétique et durabilité de l’agriculture : les limites et paradoxes du développement de la méthanisation agricole. Etude comparée en Bretagne et Grand-Est

Territoire en Mouvement, 2022
In recent years, French energy policy has been increasingly oriented towards renewable energies, creating a new demand for French agriculture, which goes beyond its mission of producing agricultural products to include energy (electricity, gas, heat ...
