Is it possible to generate enough gas to supply the whole city through its sewerage?

Question

Are there any studies available on this? Is it possible to add something to it to disguise the smell?

Answer 1

There was a study done in NY city and it was figured that the city could produce enough usable fuel gas to supply the whole state for free or very little charge. While producing the fuel they would be processing the waste. The sludge taken could be used for fertilizer/planting soil but there would be more than can be disposed of quickly hence a landfill problem. The farmers could take the "soil" and plow it into their fields but they no longer plow let alone deep plow or organically fertilize the fields.

Answer 2

the gas you want is methane, which is inherently smelly, so unless you want to build a tanker-size Lysol can you'd have to live with it. However, there have been studies into methane-based biological fuel cells for low-draw batteries, so ther is no reason why, with a little processing and perhaps adding a lot of plant waste, one could not run a cismall city off sewage. You'd need more than just residental stuff, though.

Answer 3

no , unless you want to start it up, be my guest
