Why Us

There isn’t much argument that farmers are among the world’s hardest workers – and many are under financial pressure. There is also little debate that there is a proven revenue source available – biogas.  (Photo above, Jim Muir with Congressman Joe Courtney in agricultural region of Connecticut.) 

Manure and other organic waste exist worldwide, yet only western and central Europe widely convert it into energy, animal bedding, soil amendment, useful heat etc. Why is that? To our mind it is a lack of information and hands-on support – and that is what we provide.

Since the success of any digester depends on a farm’s future existence, Agricultural Digesters LLC prioritizes financial benefit to each client. Our business models are “farmer owned” and “partnership” so that farmers receive enough financial value to pay the farm’s bills and workers in the future.

Our team consists of marketing, environmental. engineering, finance and farm supply consultants. Regardless how much support is needed, when Agricultural Digesters LLC partners with a farm, it stays with that farm every step of the way.

Jim Muir
After many years of international marketing work, Jim approached one of America’s two established biogas companies, RCM.  At the time it had sold fewer than 100 digesters. He took RCM as a client and agreed to promote and sell their systems globally, before later shifting his focus to the Northeast, USA.  Jim sold three in 2016 and two in Massachusetts have been launched, The third is under construction and will be the first modern agricultural digester in the state of Connecticut.

In 2017 RCM was absorbed by another company and Muir took as a client PlanET Biogas, a major international company based in Germany that had built over 500 systems worldwide. This was a comfortable fit since Jim’s international marketing company, Muir Marketing Solutions, had helped foreign manufacturers expand in America for decades. He was offered the opportunity to lead PlanET’s sales effort in the northeast, America’s most populous region and one of great importance to dairy production.

Today, while launching Agricultural Digesters LLC, he maintains business relationships with several experienced American and European technology providers.


Mike Curtis, PhD, PE
Most recently Dr. Curtis was Director of Project Development at Quantum Biopower, a CT merchant Anaerobic Digester company.  There he created and pursued several large digester development projects in the dairy industry and developed great expertise in ‘Organic Soils’ creation and leads a team recently awarded a $500,000 grant from the Vermont Phosphorus Innovation Challenge.  Prior to that, he spent 26 years at Fuss & O’Neill Consulting Engineers of Manchester, CT.  At F&O, Dr. Curtis was the Executive Vice President of Strategic Development and he led a staff of 100 professionals in 8 different business units.  His background includes five years with the Connecticut DEP Bureau of Water Management’s Planning Section followed by two years at the University of Connecticut Civil Engineering Department.  He is a lecturer in Entrepreneurship at Trinity College.  When not there, his work touches nearly all aspects of the biogas field, ranging from process efforts to optimizing energy, solids offtake and the sale of these materials to the benefit of digester owners.


While not every farmer we meet purchases a digester, all consider it.

John Muir, famous Scottish/American (1838-1914) devoted his life’s work to preserving the natural environment. He was the “Father of America’s National Parks”, founder of the Sierra Club and advisor to President Theodore Roosevelt.

Though probably not related, we are proud to work toward environmental preservation through the elimination of methane from the atmosphere – a leading cause of global warming.
