Food or Fuel? How will changes to ethanol subsidies affect food / fuel debate? Will cellulosic biomass like switchgrass ever work? This #AgChat conversation touches on one of the hot topics in agriculture.
Ted Funk, a University of Illinois Extension agricultural engineer with the Department of Agricultural and Biological Engineering (ABE), and Matt Robert, an ABE research engineer, constructed two biofilters on the ABE research farm to reduce odor emissions by up to 90%.
"The new design uses 30-inch concrete silo staves that fit together like puzzle pieces," said Robert.
The biofilters media is expected to last between three and five years and cost about dollar per cubic foot per minute (cfm) of air handled.
"Reducing odor and being a good neighbor sound good until it comes to the pocketbook," said Funk. "Biofiltration has been around a long time in other industries, but it's never been brought down to a cost that the livestock industry can handle."
