The determination of methane performance in different substrates via Batch tests is carried out using the German VDI-4630 standard in approximately 40 different laboratories installed in Germany. The results obtained in the methane yield of the substrates valued at the laboratory level show great correspondence with those achieved at real scale in the active plants. The Biogas Guide compiled by KTBL German Agency based on the results obtained by several well-known laboratories and institutes in that country, has shown that the accuracy of these results can be taken into account for the economic planning studies of new biogas plants. Fermentation tests are the most accurate method for determining the methane yield of the parts of the plants under analysis. In recent times, the use of biogas laboratories has increased in the validation of methane yield at the laboratory scale of different substrates, motivating the cooperation and use of standard research protocols among them, thus ensuring a high quality of the results obtained and its replicability.]]></p></abstract>

La determinación del rendimiento de metano en diferentes sustratos vía pruebas Batch se realiza mediante la norma alemana VDI-4630 en aproximadamente 40 diferentes laboratorios instalados en Alemania.

La guía de Biogás compilada por la agencia alemana KTBL basada en los resultados obtenidos por varios laboratorios e institutos bien conocidos de ese país ha mostrado que la exactitud de dichos resultados puede ser tenidos en cuenta para los estudios de planificación económicas de nuevas plantas de biogás. Las pruebas de fermentación es el método más exacto para la determinación del rendimiento de metano de las partes de las plantas objeto de análisis. En los últimos tiempos, se ha incrementado el uso de laboratorios de biogás en la validación del rendimiento de metano a escala de laboratorio de diferentes sustratos, motivando la cooperación y utilización de protocolos investigativos estándar entre estos, de esta forma se asegura una alta calidad de los resultados obtenidos y su replicabilidad.]]></p></abstract>
