| Abstract |
The engineering and economics of the direct application of a geothermal hydrothermal resources to a vertically integrated livestock complex was studied under DOE Contract DE-AC07-78ET28442. The study was conducted by a team of industry firms and supported by an Idaho Advisory Board. A system of feed production, swine raising, slaughter, potato processing and waste management was selected for study based upon market trends, regional practices, all commercial hardware, resource characteristics, energy and biological cascading considerations. The 160 acre complex has a 115 million Btu/hour (34 MWt) peak geothermal load; has an installed capital of $35.5 million with a payout of owner invested capital of just over three years and total debt payout in 12 years. The yearly production amounts to 150,000 hogs, 28 million lbs of processed potatoes, 7300 tons of fertilizer, and on the order of 1000 continuous horsepower from methane. The total effluent is 200 gpm of irrigation water. The study is presented in DOE Report DOE/28442-1, February 1979. |
