Biogas is an energy source with huge potential. It is a 100% renewable source and results from the anaerobic digestion (decomposition in the absence of oxygen) of different types of organic matter.
Different types of organic waste, from domestic, agricultural and industrial sources, as well as sewage and manure can all produce biogas. This makes it a very versatile energy source, and one that prevents waste.
Biogas can be converted to produce electricity, heat or fuel. Using it prevents the release of methane gas into the atmosphere – methane is a pollutant that harms the ozone layer. Biogas generation recovers waste that would otherwise pollute the environment or end up in landfills, as well as reducing reliance on fossil fuels.
Biogas is obtained from organic matter in four steps that occur in what are called biogas digesters. They are usually present near sources of organic waste such as agricultural leftovers or are part of sewage treatment plants.
Resalta designs and develops biogas projects in order to take advantage of the potential of organic waste as fuel, by carefully taking into consideration the organic matter available, its location and other criteria to create an optimal facility for the production of renewable energy.
