The production of biogas is emerging as an alternative source of energy and also as a solution to many economic, social and environmental problems.
Because biogas production brings economic, environmental and social benefits.
For the producer or entrepreneur: it will be possible to use electrical or thermal energies generated by biogas for domestic supply of the property or business, reducing dramatically the consumption of firewood or electricity. Additionally, it is possible to receive credits by providing power to the grid.
There is also the possibility to generate biomethane that can be used in vehicles converted to Natural Gas, instead of diesel or gasoline, cutting costs.
In addition, biofertilizer, produced in the biogas process, can be used or sold.
For Brazil: increasing the agro-industrial production, it generates more revenue for the country.
With the production of biogas - mainly from animal waste - the producer or entrepreneur reduce dramatically the soil, groundwater, rivers, and reservoirs contamination.
In addition, it avoids greenhouse gases emission into the atmosphere, such as methane and carbon dioxide produced during wastes decomposition. These gases cause a rise in planet temperature.
By removing wastes and residues from the environment, it avoids unpleasant odors and the spread of diseases caused by flies and mosquitos attracted to this organic material.
Another social benefit is the democratization of energy use. Due to the fact that it is a decentralized production, it is possible to use electricity and gas to supply kitchens, for example, in isolated communities.
The Energy Research Company (EPE) considers that the energy potential of biomasses* in Brazil will jump from 210 million TOE (tonne of oil equivalent) in 2013 to about 460 million TOE in 2050.
The Brazilian Association of Biogas and Biomethane (Abiogás) considers that the national potential is about 20 billion cubic meters per year in the sugar and ethanol industries, as well as in the food production. Concerning the basic sanitation sector, solid wastes and wastewaters, the potential is 3 billion cubic meters a year.
