Biomethane from Garbage: Turning a Climate Enemy into Clean Energy - VIDEO
Garbage that has accumulated since 1991 in the two landfills in the municipality of Caucaia has become a biomethane deposit that supplies industrial and commercial companies, thermoelectric plants and homes in Ceará, a state in northeastern Brazil.
The GNR Fortaleza plant extracts biogas from 700 wells installed in the landfills and refines it to obtain what it calls renewable natural gas - which gives the company its name - as opposed to fossil natural gas.
