It is a mixture of gases consisting primarily of methane and carbon dioxide, normally obtained by treating domestic, agricultural and industrial wastes by means of anaerobic biodegradation process (in the absence of oxygen).
Biogas generates electric and thermal energy, as well as biofuel (biomethane). During the process, it also produces biofertilizers.
Farmers, landfills and industries related to agriculture. It is also possible to produce biogas with sewage and food waste (domestic, commercial and industrial).
The first step is to make a Technical and Economic Feasibility Study, which means an analysis on the biogas production potential of the agro-industrial, organic and animal wastes that are available, as well as to find the best technological solution.
CIBiogás advises every step of the biogas deployment and post-deployment, and also has a network of partners that can meet all customers with specific solutions for each type of need.
Just after the Technical and Economic Feasibility Study.
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.
