Founded with a clear purpose
Bennamann is a Biomethane solutions partner transforming waste methane into clean, renewable fuel for multiple sectors.
Our technologies support farming, transport, and industry—delivering sustainable energy, reducing emissions, and driving the transition to a low-carbon, circular economy
Our Journey
Bennamann was founded in 2011 by Dr. Chris Mann after discovering the energy potential of methane from decomposing grass. They found that one square metre of grass holds energy equivalent to a litre of petrol.
The breakthrough came when they partnered with dairy farmers, realizing that cows efficiently extract energy from grass, yet their manure still contains significant untapped methane. Natural cow digestion pre-breaks down the slurry, making methane capture even easier.
By harnessing fugitive methane, Bennamann reduces agriculture’s environmental impact. With methane having 84-87 times the warming effect of CO₂ over 20 years, every kilo captured offsets emissions and generates clean energy.
“As a physicist by training and having worked in the space industry, I never imagined I’d end up working with cow manure and its potential as a source of renewable energy. But a chance encounter with exploding bags of grass clippings in Florida, set me on a path that has led to what I believe is a transformative solution, not only for farmers, but also the environment.”
