Rio Company Building Two Plants to Convert Waste Into Clean Energy

RIO DE JANEIRO, BRAZIL – This will be the role of the two Gás Verde S.A. plants inaugurated on July 4th, in the state of Rio de Janeiro.

The units are located in sanitary landfills in Seropédica and Nova Iguaçu, both in Rio’s metropolitan area.

According to Gás Verde S.A., biogas is cleaner than natural gas derived from oil. Once refined, it is marketed as fuel for vehicles and industries.

The gas extracted from waste feeds the company’s thermal power plants, already connected to the power grid.

In Seropédica, biogas is purchased from Ciclus, the company that manages the local sanitary landfill, perhaps the largest in Latin America, receiving approximately 10,000 tonnes of waste from the municipalities in greater Rio de Janeiro daily.

The plant can produce 200,000 cubic meters of gas per day, a volume able to fill the tanks of 13,000 vehicles. The unit is expected to produce 73 million cubic meters of renewable natural gas (GNR) per year when it is in full operation.

At the Nova Iguaçu plant, the biogas coming from the landfill managed by Foxx Haztec is purchased by Gás Verde and used to feed its thermal plant.

The plant uses 9,500 cubic meters of biogas per hour to produce 150,000 megawatt-hours (MWh) of energy per year, a volume capable of supplying 70,000 homes.

According to Gás Verde, S.A., since it is a renewable source, the energy generated is less polluting than thermal energy powered by coal, oil, and natural gas.

As a result, it helps to reduce greenhouse gas emissions, in addition to providing financial gains for landfills.
