Whey Cool: Dairy Waste Turned into Electricity
MARCH 18, 2013John Roach, NBC News
Milky rinse water flowing from Wisconsin cheese factories will soon be used to generate enough electricity for 3,000 homes, thanks to an innovative solution to a growing wastewater problem.
A new facility will take milky rinse water from five local cheese factories and use anaerobic digesters to convert it into methane gas, which will be used to generate electricity. The leftover residue, in a solid state and thus with less environmental complications, will eventually be sold as fertilizer.
Heat from the electric generators will be captured and used to warm the building, preheat the milky residue and maintain the temperature of the anaerobic digester.Read more: NBC News
