Manure Converted to Clean Energy?!

Share this on:

It’s true!   North Carolina is not only known for its Carolina blue skies, but also for its humongous hog farms.  Typically all the waste produced by thousands and thousands of hogs fills stinky lagoons, and sometimes overflows onto the surrounding landscape.

The hog waste produces methane and ammonia which, thanks to Duke University, Duke Energy and Google, is now being converted to electricity and fertilizer in Yadkinville.  A new cleaner, innovative waste-to-energy system is in place which improves air quality, not only for the farm’s neighbors, but also for the hogs, whose mortality rates will now be lower (at least until slaughter).

According to the Los Angeles Times, “The digester captures methane equivalent to 5,000 metric tons of carbon dioxide per year and produces enough electricity to power 35 homes a year.”

Currently, methane “digesters” on farms across the U.S. produced 435 million kilowatt-hours of electricity, which is enough to power 25,000 homes for a year.  Let’s get the rest of the factory farms to clean up their messes with this technology!
