Reply #1: A soy processing plant in our local industrial park [View All]

has these huge ponds where the by product decomposes and it smells just like you'd stepped in someones shit and anyway after a while and after many complaints they covered the ponds with a rubber membrane and pipe the gas back to the plant and use it for all they're heating. Processing soy uses a lot of heat. They may even sell some of it to the natural gas power plant that is directly across the road from them I don't know but anyway they are doing this very thing and it saves them a ton of money and a shitpot full of complaints.
To me the interesting part is that membrane is about a half inch thick and a cross section of it looks like a car tire sidewall only thicker. These ponds are several hundred feet by several hundred feet and the membrane will be 12 to 15 feet above the water level and held up by the pressure of the gas being created. Its really something to see.
