The Biogas Map, a dynamic map created by CIBiogás (International Centre for Renewable Energies) to identify biogas production in Brazil, indicates that the state of Rio Grande do Sul currently has 18 operating biogas plants. From 2003 to 2019, 238,371 m³ of waste and effluents were treated annually. As a result, mitigated greenhouse gas (GHG) emissions are estimated at 1,069,928 tCO2 per year. There are 13 biodigesters mapped, technology used for the treatment of waste. The total production of biogas reaches 3,125,329 m³ per year, and its application can be both thermal and electrical.
The agricultural sector is one of the sectors that can benefit the most from biogas production solutions, because in addition to using natural gas as a fuel for transporting vehicles, it produces an enormous amount of organic waste, which in turn can be used to generate energy, biofuels and biofertilizers. In 2016, Rio Grande do Sul contributed 11.8% of the total Gross Value Added of Brazilian agriculture, occupying the first position in the national ranking according to the latest statistics available from the Brazilian Institute of Geography and Statistics (IBGE). The 2017 Agricultural Census, also from IBGE, indicates that the state has 364,114 agricultural establishments.
