The fossil fuel gas is receiving strong resents across the world, in a bid to cut down on greenhouse gas emissions, and are resorting to all forms of low-emission renewal energy sources.
In one of such initiatives, Iowa’s Sioux City does not seem to stay behind. It is soon to get the world’s largest methane gas facility producing the gas from cow manure! According to the Siouxland Business Journal, by next year, the plant will collect 11 million gallons of cow manure, that otherwise are left only to pollute the surrounding environment.
Thanks to the Minneapolis-based Bison Renewable Energy. To begin with 11 1-million-gallon tanks — biogas regional anaerobic digesters – it will also grow to 22 digesters after an additional investment of about $7 million.
About 65 percent livestock manure will be fed into the plant’s digesters, with the rest of the feedstock being animal fats or vegetable waste coming from food processing units. In the methane-producing process, an excellent quality glycerin will also be produced.
Though the technology is about 18 years-old in Europe, the largest plants there have a maximum of seven or eight comparable tanks, making the new Iowa-plant world’s largest of the kind.
Though good for the environment, the plan of using cow manure leaves the local residents worried of the massive fetid pooh odors.
