About 5 million head of cattle are produced annually from about 200 feedlots in the Texas High Plains with about 3.5 million head standing. Annually, the 3.5 million head of cattle produce about 28 millions metric tons of were manure (88% water). If anaerobically digested, the manure would yield about 1.4 million m{sup 3} of biogas, or about 4.4 million kWh daily. With cogeneration and nutrient recovery, the sum of the revenue sources in over $500 million annually and does no include the value of water or other byproducts such as fish and plants that could be produced from an integrated system. A demonstration unit to treat the waste from a 1000-head cattle and a 280 sow farrow-to-finish swine operation is constructed. This system employs a 6 m deep anaerobic pit for production and capture of biogas integrated with a facultative pond, a shallow pond for production of aquatic plants, and a pond for production of fish or other aquatic species. The resulting related agribusinesses would not only produce additional revenues, but would also produce energy, improve the environment though extraction of nitrogen compounds, capture of gaseous emissions, reduction of odor, and creation of wildlife habitat in consturcted wetlants.
