The article is a bit old, but still quite interesting. I don't see any reason (besides cost, yikes, 1.2 million!) that we wouldn't want to do more of this. Also, the picture they used cracks me up. :D Pig Poop Helps Google Go Carbon Neutral | Crisp Green Quote:

Every sewage treatment plant and every animal farm and every landfill should have methane digesters and collectors! Not only would this gain a lot of lost energy, it would produce a lot of high quality fixed nitrogen fertilizer - which would then replace a lot (ALL?) of the chemical fertilizers that we currently make from natural gas.
Two problems solved with one solution. Actually at least THREE problems would be solved - the natural organic fertilizer would allow the soil to be built up, and we would then stop poisoning the groundwater and rivers - and the dead zones in the ocean could start to rebound. |
Good point Neil. I didn't think about that.
