Comments on: Manchester, U.K. Producing Methane from Human Waste http://greenlivingideas.com/topics/alternative-energy/manchester-uk-producing-methane-human-waste Keeping going green down to Earth Wed, 10 Mar 2010 21:14:07 -0800 http://wordpress.org/?v=2.8.6 hourly 1 By: Alok Kumar http://greenlivingideas.com/topics/alternative-energy/manchester-uk-producing-methane-human-waste/comment-page-1#comment-1283 Alok Kumar Thu, 03 Dec 2009 19:23:55 +0000 http://greenlivingideas.com/?p=5479#comment-1283 hello mam, im Alok Kumar from India and am very interested in generating energy from human sewage. I am a final year B.Tech student and have chosen this as my final year project. i have made arrangements for a tank for sewage (solid waste) storage too. I REQUIRE YOUR HELP TO CONTINUE WITH MY PROJECT. I WOULD NEED THE REQUIREMENTS TO BUILD A SMALL SCALE PROTOTYPE PLANT. I HOPE YOU WILL HELP ME OUT. THANKING YOU IN ANTICIPATION. hello mam,

I live directly across from a sewage treatment plant in Baltimore, Maryland, USA. The treatment plant set up a cogeneration plant which essentially takes 100% of the methane produced by the human waste. Running at peak efficiency, the cogeneration produces up to 2.25 MW. That amount is only sufficient to run 50-60% of the waste plant's annual energy needs. I looked at siphoning power from the plant during non-peak times to power my neighborhood of 50 townhouses. The plant would only be able to supply 5-10% of the community's annual power usage. It get worse when you add additional homes. Bottomline: you can use the power either to power the waste plant or give electricity to 500 homes as detailed above. My opinion: calling this "green" energy for the homes is a bit of a misnomer because you still have to power the operations of the waste plant (likely a non-renewable fossil fuel). Manchester's plan would be green if the human waste produce 120% of the waste plant's energy needs, with the excess 20% sent to power homes On the surface this looks like a great idea, but you really have to investigate the numbers associated with this setup.

Sometime ago, residents of an Australian city near Brisbane had to vote on drinking filtered "pre loved" water and many thought the idea, well, stank, but converting poo to energy should be a lot more (ahem) palatable... Go Manchester! Hooray for human inventions!
