    Biomethane Potential (BMP)

The biomethane potential (BMP) can be considered to be the experimental theoretical maximum amount of methane produced from a feedstock. We determine it in a laboratory test that involves mixing the organic substrate with an anaerobic inoculum in a closed reactor that is incubated at a set temperature, with the contents mixed, for a set period of time. During this period the sample is digested and biogas is produced. The volume of biogas is monitored allowing for a cumulative plot of biogas production over time to be derived. We then analyse this biogas for its composition, in particular the methane content, in order to allow the BMP to be determined.

In our laboratory, we have two Anaero BMP systems that allow us to digest your samples and determine the biogas yield over the course of the BMP digestion which can last for 14, 21, 18, or 40 days. Our BMP analysis packages also determine the total solids (TS) and volatile solids (VS) contents of the sample and also involve periodic analyses of the composition of the biogas (for methane, carbon dioxide, hydrogen sulphide, oxygen, and ammonia) using the Biogas 5000 portable gas analyser.

We also have Deluxe versions of our BMP analysis packages that cover the important chemical and biological properties of the feedstock and digestate (the material remaining after the BMP test). Analytes that we determine in these Deluxe packages include: Total Solids, Volatile Solids , pH, Chemical Oxygen Demand (COD), Biological Oxygen Demand (BOD), Phosphorus, Potassium, Ammonia, Carbon, Hydrogen, Nitrogen and Sulphur.

Our BMP experiments are undertaken in triplicate and we report the values for each of the replicate, the mean, and the standard deviation between the replicates.
