Farm Bill Funded Project
When Danny and Josie Kluthe decided to expand their 4,000 head swine operation, they were concerned about the adverse effects of a large-scale feeding operation on their neighbors. Through a partnership with the Nebraska Public Power District (NPPD) and grants from the USDA and Nebraska Environmental Trust, the Kluthes installed Nebraska's first digester system to produce electrical energy from recovered methane.
Manure from the operation is fed to an in-ground concrete tank with an insulated flexible cover. The complete mix digester system generates methane as it stirs and heats waste. The gas is used to fuel an internal combustion engine, which produces electricity that is sold to NPPD under a buy-all, sell-all contract. The farm produces 730,000 kilowatts-hours of energy annually—enough to power 53 homes per year. Recovered heat from the system is used to maintain the digester temperature.
Danny Kluthe Farm's digester project includes the following benefits:
- Odor reduction
- Electricity production
- Prevented release of methane into the atmosphere
- Nutrient-rich fluid created as a by-product of the process for fertilizing agricultural lands
The Kluthes received additional funding for the completion of a waste control facility, a manure transfer pump, and tree planting.
You know, I think these digesters make so much sense that once producers understand them and see the value of them, there will not be a hog unit built or a dairy put in that probably will not want these installed immediately on it.
