State agency gives Hormel OK to build new $25M waste treatment facility

Published 10:51am Tuesday, July 23, 2013

Hormel Foods is clear to build an odor-reducing, $25-million inedible waste treatment plant after the Minnesota Pollution Control Agency approved an amendment to its air emissions permit earlier this month.

“We are pleased the MPCA has approved the amendment and we will begin the refined products improvement project soon,” Tom E. Raymond, director of environmental sustainability at Hormel, said via statement. “We will enjoy the full benefits of the project when it is completed in the summer of 2014.”

The new plant, built as a replacement for the current treatment plant, will process excess meat and other hog parts not used in food manufacturing. This new plant will contain regenerative thermal oxidizers, a processor of sorts, which heats hazardous or volatile fumes, converting it to water and carbon dioxide. The oxidizers should eliminate much of the smell from the treatment plant, and is expected to reduce some of the main plant’s odor emissions, as well.

The plant’s emissions should drop to less than 53 tons of particle matter a year, or a little more than a quarter of the MPCA’s particle matter limit. The plant will reduce Hormel’s already low carbon monoxide, nitrogen oxide, sulfur dioxide and carbon dioxide levels far below MPCA standards, as well.
