Pig nursery facilities (right) raise 4,000 pigs from 8-weeks old till ready for grow out by other hog finishing farms or at Doug Jernigan Farms, a three-generation family farm and employer who, a few months earlier, refinanced a first of it’s kind, in the nation, swine-turkey waste to renewable energy system (RES), with the assistance of the Department of Agriculture (USDA) Rural Development (RD) Renewable Energy for America Program (REAP) loan guarantee in Mt. Olive, NC, Tuesday, Nov. 10, 2015. Typical systems separate methane gas for energy, solids are disposed or repurposed and liquids are cleaned. This new system addition takes the watery manure effluent to a new and as Mr. Jernigan say’s “prolific profit” producing state through savings and sales. “There is an opportunity for the farm to make money doing a good thing for the environment.” The system handles about 75,000 gallons of swine and turkey waste effluent each day. Piped to a series of tanks, and mechanical equipment that separates solids, and liquids. The current treatment facility biologically removes ammonia nitrogen with bacteria adapted to high-strength wastewater; removes phosphorus via alkali precipitation; and reduction emissions of odorant compounds, ammonia, pathogens, and heavy metals to the environment. The water is cleaned for reuse in the swine and turkey operations that wash more manure into the cycle of the system. The new methane reactors (under the framework of what will be a C-span structure) use an endothermic gasifier that heats the waste solids to very high temperatures to the point that they release gases. The clean methane gas will fuel an engine that turns a 300KW electrical generator producing electricity; ethanol will help fuel farm equipment, and resulting potash solids can be used or sold for agricultural fertilizer. Excess amounts of electricity, that the farms cannot use, will be sold and transmitted to the local energy company, for use by residents
