Research proves economic efficiency of biogas in dairy farming
The generation of electric energy and the production of biofertilizers from livestock wastes is already a reality in Brazilian cattle breeding. After some frustrated experiments in the 1970s and 1980s, growers who adopt a feedlot system, in which cattle are raised in large stables, started to generate the electricity consumed on the farm, and in some cases even sell the surplus distribution companies.
The adoption of technology is still low among dairy farmers, but researcher Marcelo Henrique Otenio, who coordinates studies on biodigesters at Embrapa Gado de Leite (MG), says that the use of biogas is booming in the sector and shows returns financial resources. “We have assembled a multidisciplinary research team from several institutions and our studies indicate that it is economically viable to use biodigesters in dairy farming for free stall production systems with more than eighty cows” , reveals Otenio.
