Chile, Brazil: water utilities become energy producers with biogas

Chilean natural gas distributor Metrogas and water utility Aguas Andinas started up operations at the country’s first biogas plant installed at the Farfana water treatment complex on the outskirts of Santiago. The plant will produce 24Mm3/y of biogas and replace about 14Mm3/y of natural gas. “This is the only place in the world where biogas produced by a water treatment facility ends up being used directly in homes,” Metrogas president Matías Pérez Cruz said, adding that the biogas plant is the largest in South America. Investment in the project totaled 3bn pesos (US$5.3mn).
