A novel approach was taken to cost-effectively close a 4.86 ha unlined industrial wastewater sludge lagoon in North Carolina and reduce leachate production. A floating geosynthetic cover system gave crews and equipment access to the lagoon surface.
Geomembranes are permeable fabrics which when used together with soil have the capacity to isolate, filter, support, protect and drain. Geomembranes were previously used as canal and pond liners. However the current and largest application is controlling dangerious wastes. In several of these applications, geomembarnes are concurrently used with geotextiles or mesh which offer reinforcement or protection to the flexible geomembrane while at the same act as outlets for gases and leachates generated in certain wastes.
Rosendale Dairy – Home of new digester
Located at the Rosendale Dairy, owned by the company Milk Source, the biodigester will process 240 tons of manure per day from the dairy’s 8,500 cows, generating biogas burned as fuel in power production and a pathogen-free and nutrient-rich waste stream that is land applied as organic fertilizer. Some will be used on the dairy’s own farmland and the rest marketed at a discounted rate compared to commercial fertilizer to the dairy’s feed providers for use on their land.
Installation of Roeslein Alternative Energy’s biogas technology creates renewable
natural gas from Smithfield Foods Hog Production’s two million pigs in northern Missouri and takes sustainability to the next level.
In 2013, the Blue Mountain Biogas Power Generation plant came on line in Beaver County, Utah. Owned and operated by Alpental Energy Partners of Provo, Utah – developers of alternative energy power plants – the $17 million, 3.2 MV plant is generating electricity from biogas provided by the anaerobic digestion of swine manure. A portion of the capital costs was eligible to be covered by a U.S. Treasury 1603 Grant.
On any dairy farm, handling waste products is an important part of the producer’s farm management plan. Managing manure and other by-products is definitely a complex issue. Managing dairy wastes means protecting the quality of surface and ground water, finding ways to utilize the waste product and being “neighbor” friendly when it comes to potential odors emitted from these waste by-products
