 Charcoal as a bacteriological adherent for biomethanation of organic wastesConsolación Sánchez-Sánchez, Almudena González-González, Francisco Cuadros-Salcedo, Vicente Gómez-Serrano and Francisco Cuadros-Blázquez Energy, 2019, vol. 179, issue C, 336-342 Abstract: This paper analyses the improved energy and environmental performance of the biomethanation of a mixture of sheep manure (20% by weight) and cheese whey (80% by weight) in a reactor of 2 L capacity containing 2 g of charcoal in the form of a fixed bed with respect to the same process but without the charcoal in the reactor (control experiment). The results show an increased methane production of 27.05% and a reduction of the H2S content in the biogas of 34.7%, over those obtained in the control experiment. These marked improvements of the biomethanation process are attributable to the content of highly electropositive metals such as K and Ca in the charcoal which, because chemical reactions, can increase the pH of the medium and thus favour the processes of methanogenesis and sulphate reduction. Charcoal would act as a bacteriological adherent promoting the biomethanation of the organic waste materials used in the study.
