New York Post:

Waste not, want not is the city’s strategy for huge reserves of untapped energy bubbling up at sewage treatment plants.
The Department of Environmental Protection is looking for contractors to develop a poop-to-power project at Wards Island, one of the biggest of the city’s 14 treatment plants.
The so-called “digester gas” is a byproduct of the breakdown of sewage. Some of it has been used for heating at the treatment plants in the past, but all the excess gas has to be burned off, which creates greenhouse gases, said Deputy Mayor for Operations Stephen Holloway.

I think this is a great plan as New York City is already the Saudi Arabia on noxious fumes.
