Cleaner livestock waste

Residents near farms or livestock processing facilities will soon breathe a cleaner (and less smelly) sigh of relief.

Bion Environmental Technologies said they now have a patent approval for their phosphorus removal process in livestock waste treatment. The company said excess nutrients from livestock waste, primarily phosphorus and nitrogen, have been shown to cause serious environmental problems in the U.S. and worldwide.

The patent application was made on April 15, 2005; upon publication and issuance, the patent will be officially granted and will remain in force until December 26, 2021.
