“…Anaerobic digestion (AD) has been used for its emphasis on energy conservation and recovery and desire to obtain beneficial use of organic waste [1][2][3]. Acting through a series of complex microbiological processes, diverse types of bacteria work in an assembly line fashion going through four stages: hydrolysis, acidogenesis, acetogensis and methanogensis [4].…”

Biochemical methane potential (BMP) tests are widely used for characterizing a substrate’s influence on the anaerobic digestion process. As of 2018, there continues to be a lack of standardization of units and techniques, which impacts the comparability and validity of BMP results. However, BMP methods continue to evolve, and key aspects are studied to further eliminate systematic errors. This paper aims to update these key aspects with the latest research progress both to introduce the importance of each variable to those new to BMP measurements and to show the complexity required to design an accurate BMP test.

“…En la tabla 5 se muestra que el porcentaje de humedad fue de 11,11 % por lo que se asegura que este tipo de fango resulta favorable para el proceso de estabilización en menor tiempo; un alto contenido de humedad en los fangos activos proveniente de plantas de tratamiento de agua residual indica que no pueden ser compostados, primero necesitan ser mezclados con materiales secos. Además, un bajo porcentaje de humedad en estos fangos no solo ayuda a aumentar el poder calorífico sino también a elevar el contenido de materia seca [18]. Se obtuvo un 65,87 % de materia orgánica lo cual es un factor importante y conveniente para ser estabilizado; según Pérez [19] los fangos provenientes de las PTAR contienen un elevado porcentaje de materia orgánica derivándose en altas concentraciones de microorganismos, el rango idóneo es entre 25 -50 %.…”

Los fangos activos generados por las plantas de tratamiento de aguas residuales contienen altas concentraciones de microorganismos patógenos y materia orgánica, convirtiéndose en un problema ambiental, el objetivo de esta investigación fue la estabilización de fangos mediante la técnica de Bokashi, se realizó un diseño completamente al azar (DCA) con cuatro tratamientos y cuatro réplicas. El T1 compuesto por 35% fango y 65% Bokashi, el T2 tuvo 45% de fango y 55% de Bokashi, el T3 55% de fango y 45% de Bokashi, y el T4 65% de fango y 35% de Bokashi. Los análisis estadísticos ejecutados mostraron que el T3 alcanzó mejores resultados para una estabilización de los fangos, presentando parámetros de valores óptimos de humedad de 46,35%, carbono de 42,73%, nitrógeno 1,55%, el valor de pH 6,4 y la temperatura que una vez estabilizada se mantuvo entre 30-31 ºC presentando potencialidades como alternativas eficiente, para la estabilización de fangos provenientes de plantas de tratamiento de aguas residuales para ser utilizado en el sector agrícola.

“…Anaerobic digestion is a biological process where biodegradation of organic substrates (alone or through codigestion) was carried out by a microbial consortium giving in this way biogas (mainly composed by methane and carbon dioxide) and digestate. AD processes were widely used for energy conservation and recovery and to valorize organic waste [1][2][3].…”

Biochemical methane potential (BMP) is essential to determine the production of methane for various substrates; literature shows important discrepancies for the same substrates. In this paper, a harmonized BMP protocol was developed and tested with two phases of BMP tests carried out by eleven French laboratories. Surprisingly, for the three same solid tested substrates (straw; raw mix and dried-shredded mix of potatoes, maize, beef meat and straw; and mayonnaise), the standard deviations of the repeatability and reproducibility inter-laboratory were not enhanced by the harmonized protocol (average of about 25% depending on the substrate), as compared to a previous step where all laboratories used their own protocols. Moreover, statistical analyses of all the results, after removal of the outliers (about 15% of all observations), did not highlight significant effect of the operational effect on BMP (stirring, automatic or manual gas quantification, use of trace metal, uses a bicarbonate buffer, inoculum to substrate ratio) at least for the tested ranges. On the other hand, the average intra-laboratory repeatability was low, about 7%, whatever the protocol, the substrate and the laboratory. It also appears that drying the SA substrate, which contained proteins, carbohydrates, lipids and fibers, does not impact its BMP.
