About Us

Bio-Gas Technologies' goal is to be a part of the circular economy by reducing greenhouse gas admissions through the creation of renewable energy at landfills. We have the expertise in design, build, and install Landfill Gas-to-Energy Systems throughout the world.


Remembering Our Founder

Founded in 1996 by James R. Hiendlmayr, Bio-Gas Technologies has a long history of renewable energy projects including Natural Gas, Coal Mine Methane, Cogeneration, and Landfill Gas to Energy systems. James Hiendlmayr built one of the first Landfill Gas-to-Energy Systems in the United States through a partnership in 1984 in Burlington Vermont, and since has developed, owned, and operated renewable energy systems across the United States.


Today, Bio-Gas Technologies owns and operates Renewable Energy Services of Ohio, a 2.4Mw Landfill Gas-to-Energy system in Milan Ohio. Using landfill gas (LFG) to generate energy and reduce methane emission produces positive outcomes for our local community and the environment.
