ODOR CONTROL
Your Neighbors Don't Have to Know
Odor is the leading reason compost facilities are shut down. Owners developing new facilities or altering existing ones without properly understanding the odor implications are putting their entire investment at risk.
Find out why none of our customers around the world have been shut down for malodors.
Managing Oxygen Levels
Ensuring aerobic bacteria are prominent is essential to controlling emissions and odors. At GMT we ensure this with aeration systems that keep oxygen levels at 13% and can effectively aerate settled feedstocks. We also create “compost recipes” that are balanced and properly bulked.
Scrubbers and Covers
Even under aerobic conditions some odors and emissions will be formed. At GMT, we control these by running exhaust air through a biofilter or biocover removing up to 95% of the odorous compounds. If additional odor and emissions control is required, we can integrate an acid scrubber or washbox, allowing us to remove up to 99% of the odor and select compounds.
Odor Control & Modeling
GMT creates effective odor models that look at the number of odor dilutions required to remove 98% of the odor, factoring in wind conditions and topography. Once evaluated, we can make informed decisions about odor control measures such as enclosing the composting process, putting the system under negative aeration, or adjusting site location.

“I first met Jeff around 1992, when my agency assigned me to find out why a major composting operation in our jurisdiction was creating odors that could be smelled 11 miles away. At that time Jeff was the manager of the LRI facility in Gig Harbor, WA. Jeff took me under his wing and taught me the basics of composting, and how to do it odor free. As the last two decades have gone by, Jeff became the go-to guy in the State of Washington, whenever I needed to learn something about composting not yet covered in the literature. My agency has never had to write a nuisance ticket on ANY of the facilities he was involved with. Lenz Composting, the composting factory at LRI Puyallup, and LRI Gig Harbor facility all have clean records with us. If you have two dozen suddenly deceased cattle to compost, (all in one pile), there is no one else I would trust to do the job. A couple of winters ago Jeff did just that at Lenz Composting, ODOR FREE! I’ve seen it, I’ve smelt it, and my agency has pictures to prove it.”
