Our laboratory and experienced professional staff are ready to serve your need

At Digester Doc we have over forty years of experience in the anaerobic digester industry among our staff. Our focus is improving anaerobic digestion sustainability through scientific advancement, where we’re on the cutting edge of research and development. We are not just an R&D firm, though. We started in a humble garage, and we have never forgotten where we came from. We pride ourselves as the only full service AD consultation lab, with experience in every aspect of the anaerobic digestion industry.


40+ Years of Experience

Reduce Your Downtime

We have seen the worst kinds of upsets out there, and we know how to fix them. Our experience even allows us to correct several issues before a project is built.


Increasing Gas Yields

We offer CI evaluations, RIN/LCFS navigation, and project feasibility analysis to optimize your production

Laboratory Services We Provide

  • A BioMethane Potential Test is a standardized laboratory test to determine the gas potential from a feedstock by creating a mini-digester in the laboratory. To be exact, each BMP Test is actually (3) 500 mL glass bottles of the same feedstock automatically agitated by a stir rod. The gases produced exit the bottle and are measured through a series of machines that sends the data to a computer station. The data is stored, charted, and analyzed by our scientist and the report is generated. The process takes approximately 45 days or less from receipt of samples.
  • Deliverable: 1 BMP Test Report with 30 minutes of consulting time with a scientist included to explain data and answer questions.

  • This is a combination of analytical and chemistry tests to determine the current nutritional health of any sample. Our scientists will then take that data and screen for nutrient deficiencies or compound concentrations that are toxic to methanogenic species.
  • Deliverable: 1 TND Analytical Report with 30 min of consulting time with a scientist included to explain data and answer questions. This report reviews a total of 18+ chemical and physical characteristics that contribute to AD failures and issues. This database grows as we continue to learn additional information regarding biological sensitivities to the biological world.

  • This is a test looking over the low chain fatty acids, focusing on Acetic, Butyric, Caproic, Heptanoic, Propionic, and Valeric Acids.  This then allows us in combination with pH and Alkalinity to understand and predict the occurrences of foaming and other minor disturbances to anaerobic systems.
