NYC to Turn Sewage Into an Asset
"For the city's Department of Environmental Protection, which is to issue its strategy on Wednesday, it is a shift. Until now, the agency has mainly played the role of water utility and environmental steward rather than energy producer," writes Mireya Navarro of the NY Times.
According to Navarro, "about half of the methane produced by the city's plants is already used to meet about 20 percent of the energy demands of the city's 14 sewage plants, whose electric bills run to a total of about $50 million a year. Now the city wants to market the other half, which is burned off and wasted."
