Odor control and abatement is a concern of many rendering and animal protein companies. Aside from being an environmental issue, odorous gases & compounds can also pose problems for nearby residential communities, where residents expect an odor-free environment.

Plant Odor Survey
One of the value-added services we offer customers of Hydro Solutions is a comprehensive survey of plant odors. Starting an odor removal program is a great opportunity to have a fresh look at your facility to identify areas of concern that may be a source of odor, and establish a benchmark for continued improvement.
Here is a partial list of areas we review during a plant odor survey, each of which can be air tested for common emission compounds that are generally found to generate odor complaints.
Loose, blowing MBM
Leaks in condensate system
Lagoon issues
Grease tanks
DAF systems
Open doors or bays
Negative vs. positive air pressure in rendering plant
Wall fans
