Anaerobic Digestion Experts

Experience is Key

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.

Get the job done

We’ve worked with clients large and small. Farm waste currently makes up a large portion of our business. Still, we’ve worked with digesters in practically every industry where they are used, and we have solutions to fit every digester operation.  

Our team of seasoned professionals has the expertise to get the job done right the first time. We identify ongoing challenges the industry faces, consult on appropriate project design, and work to develop lasting solutions through scientific understanding, technology, and innovation.

Championing biogas

We offer the missing key to enhancing your facility; a deeper understanding of biology. Our ultimate goal is to create a complete account of the biological needs within digester systems and unlock the true potential of the AD process to avoid the need for shutdowns.
