In a city as big as New York, sewage can become a problem. Currently, the city spends around $400 million each year processing wastewater. But a proposed solution could see all that waste turned into energy.
The idea is to take the wastewater — of which around 1.3 billion gallons is produced daily — and extract gases such as methane, which could then be sold or used to power homes. And this would actually end up being cheaper than the current method of simply treating the water.
“There’s nothing in here that’s pie in the sky,” city councillor Caswell F. Holloway told the New York Times. “While we’re early in the process, it’s real.”
City officials hope to begin in 2013.
