The plant is located at the 140ha Jardim Gramacho landfill near Rio de Janeiro.

FirmGreen, a small renewable-energy company based in Newport Beach, California, and other US green-technology suppliers are benefiting the loan by supporting exports of equipment and services for the development of the biogas project Brazil.

Ex-Im Bank chairman and president Fred Hochberg said, "It [the project] enables the Brazilian project owner, Gas Verde, to convert an environmental hazard into a green-energy source that will reduce local emissions of greenhouse gases as well."

The plant is expected to capture and treat 20,000m3/hr of raw landfill gas, subsequently producing 9,000m3/hr of fuel-grade biomethane gas; the biomethane sold will be transmitted by a pipeline to a nearby refinery owned and operated by Petroleo Brasileiro.

Gas Verde the project will contribute to 1.4m/t of greenhouse-gas reductions per year.
