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.
We have a custom blend of reactants to treat both wet air scrubber and fugitive odors associated with animal rendering plants. REACT-OX® and HYDROFRESH® product lines have been lab studied and field tested to prove they work.
Hydro Solutions, Inc. has over 15 years of experience in addressing these issues. Using state-of-the-art testing, odor surveys, and equipment surveys, we are able to identify problem areas and develop an engineered solution to remove odors below thresholds.
Compound Emissions
The airstream from a rendering operation could contain a number of compounds, according to a 1995 report by the EPA. Below are the most common compound emissions, according to the EPA report:
- Particulate
- Ammonia
- Hydrogen Sulfide
- Organic Sulfides
- Disulfides
- C-4 to C-7 Aldehydes
- Trimethylamine
- C-4 Amines
- Quinoline
- Dimethyl Pyrazine
- Other Pyrazines
- C-3 to C-6 Organic Acids
- C-4 to C-7 Alcohols
- Ketones
- Aliphatic Hydrocarbons
- Aromatic Compounds

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.
- Open doors or bays
- Negative vs. positive air pressure in rendering plant
- Wall fans
- Roof vents
- Loose, blowing MBM
- Leaks in condensate system
- Lagoon issues
- Grease tanks
- DAF systems
