- AmyVernon, on 07/11/2008, -1/+11good for them. rock on...
- recycleraccoon, on 07/11/2008, -0/+9While this is a positive way to use methane, I think the article does not deal with some related issues. Landfilling should be a last resort for product disposal. Also, while they are able to capture methane and create a lot of power, they don't mention how much methane is not being captured. Most landfills admit to only capturing a small portion of this GHG.
- marabout40, on 07/11/2008, -0/+7Algae is actually a great alternative energy source and it also has the potential to help clean up our CO2 problem. http://oakhavenpc.org/cultivating_algae.htm

- inactive, on 07/11/2008, -0/+6I don't know if anyone knows the answer to this but here's the question...
Why is the gas purification process handled at the remote site (UNH) and not at the landfill? I am assuming that in the future they will provide power to more than one site and it seems ineffiecient to have to have a purification building at every destination as opposed to just one at the source. BTW, good article. - Wind4ever, on 07/11/2008, -0/+6It is so simple and still we are just made our first steps in this direction. It is Win, Win and Win situation. Burning the landfill gas reduces many times the climate change effect of it, can produce Electricity and it can produce Heat (with little more effort can Cool too). This process can have more than 95% efficiency (regular power plant is between 35% and 45% efficiency).
Combining landfill gas and co-generation is a great idea. Wonderful article! - sarafina42, on 07/12/2008, -0/+4The gas needs to be purified for UNH because they are using it with existing cogenerators that were made to produce heat and electricity from natural gas. Purifying the landfill gas allows the existing cogenerators to be used, but fired by a different energy source. If the landfill gas was used for generating electricity at the landfill itself, I don't think it would need to be as purified.
- ukthom, on 07/12/2008, -0/+4Having gone to UNH myself, and having worked on the campus while all of the construction of the Co-Gen plan was going on, I can say that this article sums up a great deal of foresight and planning on the part of the university. I suggest going to their website (unh.edu) and doing some research into this, if you are at all interested. Millions are being spent at that school, and being an alumni, it's good to see my donations to the school being put to a decent use.
- UrbanGreen, on 07/12/2008, -0/+4It is great to see something that saves the school money and helps the environment.
- dantenhickville, on 07/12/2008, -0/+3Trash to fuel is one of the smartest solutions purposed. It actually will reduce the amount of space we waste on waste.
- syowr, on 07/12/2008, -0/+2One of my first jobsites as an electrical apprentice was building a gas extraction and co-generation plant at the Shepard Landfill in Calgary AB. In the pilot project we did at the East Calgary Landfill a turbine generator was used briefly till the impurities in the landfill gas caused it to fail. However there is no need to purify if you are using a generation package that can handle more impurities, a standard combustion engine works fine.
They were also testing out a sealed section that they inject water into to stimulate decomposition and LFG creation. When they had the sealing cover off that section of the landfill smelled like a billion fresh diapers so it seems to work. - hansk, on 07/12/2008, -2/+3I would have sexual intercourse with her.
- ukthom, on 07/12/2008, -0/+1I think it was because the city of Rochester wasn't going to foot the bill to build the purification plant on site (or perhaps there wasn't any room). I also think that UNH wanted to have the purification/co-gen plant on-site to enable direct study and interaction from the students on campus. Rochester, where the landfill is located, is not easily accessible by a majority of the student population.

- shadowsurfr1, on 07/12/2008, -0/+1That's my school, too!
I work for them in the dining hall and we're constantly looking for ways to make things more sustainable. Currently, all food waste from the dining halls goes back to a farm to get turned into compost. - returnofthemac, on 07/12/2008, -0/+0hey wow! my dad was a civil engineer on this project!
you can digg me down cuz i'm lame, but it's cool to see a project a family member contributed to make it to digg's front page - thats all - bokono37, on 07/12/2008, -3/+2"This project truly closes the loop by making us of trash. This fundamentally shifts the way that the university and community looks as waste." Write much?
- themonkman, on 07/12/2008, -4/+1Damn. You must've had a lot to drink tonight!
