Bertrand Guerin is an agricultural entrepreneur in the south-west of France. On his farm, Clottes Biogaz breeds 100 dairy cows and since 2011 he has been producing biogas from livestock waste. Since 2022, he has decided to invest in the production of biomethane as a biofuel. In fact, the farm’s tractors will be powered by biomethane and the remaining part will be sold to power other heavy vehicles. Guerin is one of the many French agricultural entrepreneurs who have embarked on the road to biomethane.
