Perspectivas del ensayo de Potencial Bioquímico de Metano - PBMpara el control del proceso de digestión anaerobia de residuos

[摘要] AbstractAnaerobic digestion is a biological process that achieves two purposes simultaneously, waste treatment to control environmental pollution and the recovery and valorization of by-products generated: methane as a source of renewable energy and digestate for agricultural purposes. To determine the methane production capability, the anaerobic biodegradability of an organic substrate, the selection of potential substrates and inoculums and the performance prediction of full-scale digesters, bench scale procedures as Biochemical Methane Potential (BMP) test, are performed. This article shows a refection on different aspects related to this important test, such as the diversity in the experiment denomination, the different modifcations in operational and experimental conditions, the different use of measurement units, the required equations for methane quantifcation, among others, these have given place to various methodological approaches which differ in conditioning factors for its application and comparison with results of other studies. With this refection, the usefulness of this assay and the need to standardize it is ratifed. Therefore, the experimental and operational conditions and the appropriate units should be reported, to avoid methodological confusion and permit a greater reproducibility. Additionally, it is recommended to deepen in the methodological analyses of different measurement methods to obtaining comparable results. Keywords:anaerobic digestion, anaerobic biodegradability, biochemical methane potential - BMP, organic waste.
