By LAURIE WELCH South Idaho Press
The construction portion of the new methane plant near Rupert should be complete by the end of July.
Whitesides Dairy is the first in Mini-Cassia to build an anaerobic digester which will decompose manure and capture the resulting methane gas which can than be sold as fuel.
"The positive economic effect this will have on Idaho's and the nation's dairy and energy industry is immense," said Joe Cannon, president of Cannon Builders Inc., an Idaho based company which was awarded the initial phase construction contract.
"Cannon Builders and I personally are pleased to be a cornerstone of a revolutionary technology that will positively affect the United States energy markets in such a dramatic fashion. ITR (Intrepid Technology and Resources, Inc.) is anticipating that the total revenues they will generate just in southern Idaho will exceed 50 million dollars in annual energy sales by 2008," Cannon said.
Dennis Keiser, president and CEO of Intrepid Technology and Resources Inc. said the concept of the anaerobic digester has been around for hundreds of years and during the 1970s energy crisis the methods were dramatically improved.
The concept behind the digester is to decompose manure without oxygen (anaerobically). Bacteria is used to break down the manure which releases methane along with other gases. The methane is then captured and sold for fuel.
Steve Whitesides, who owns the 4,000 head dairy with his brother Brent, said Whitesides Dairy hopes to capture and market the methane gas and sell it for fuel as well as use it at the dairy.
Keiser said "The economic impact of this project to ITR and its shareholders is tremendous. With the new additional distribution and compression capabilities we have acquired in the WOBF Venture Partners acquisition ITR is uniquely positioned to become a significant contributor to successfully solving the rapidly escalating and volatile world energy prices."
We represent a company with an unlimited commodity, industrial and animal waste, a proprietary digestion or refining system to turn the commodity into green energy and the added capabilities of distributing that product and guaranteeing the future delivery price for as far out as a decade. No other energy company in the world can do that today and we are on the verge of making this happen." Keiser said.
The project is planned in two phases. During the first phase the tanks will be built and studies conducted to determine the best practices. The company will then use the studies to streamline production and expand to full capacity during phase two, Keiser said.
The facility will be built to allow additional tanks and capacity to be added as the market for the gas expands, he said.
The Rupert digester will be used as a platform to test the different methods available to cost-effectively utilize the gas produced on a commercial scale.
Keiser said the appropriate studies have not yet been done on herds this size.
In the past it has taken 25 to 30 days to complete the decomposition cycle which can now be accomplished in five to six days, Keiser said.
The digester will produce biogas with up to 80 percent methane content which is 33 percent higher than the industry standard.
"It could have far reaching benefits for the area because of all the diaries," Keiser said.
