MSW Management Magazine: OMI Industries and How to Control Odors at Material Recovery Facilities

In the material recovery facilities (MRFs) arena, countering odor and dust issues can be a tremendous challenge. This often comes down to the waste processing in these facilities being more extensive and time-consuming. In addition, “dirty MRFs” tend to deal with a wide-range of organic waste, which results in a high-level of foul odors in highly enclosed structures.

Fortunately, for facility managers there are solutions for safely and effectively countering dust and odors in MRFs. This was the key theme of a recent MSW Management article, which featured commentary and insights from Dr. Laura Haupert, Director of Research and Development at OMI Industries.

Dr. Haupert offered the following comments about the sources of odors in MRFs:

From an odor perspective, just as we see in any solid waste application, there are a wide-range of odor sources within any MRF. Many odors coming from waste is caused by the biological decomposition of that waste. Waste tends to be more odorous when it has a higher amount of organics in it. These odors often come from decomposing food waste in many of the recycled materials, which have become sour or moldy.

In addition, many of these materials have been left in a hot or damp environment for an extended period of time, which can further compound any odor problems. In addition, when it comes to recycled materials there are many kinds of odor sources including moldy cardboard materials, and food waste, which decompose and offer a variety odors.

As food scraps, along with other issues with citizens not properly sorting their recycling, make these odors an ongoing challenge for MRF facility managers. The odorous gases from hydrogen sulfide, mercaptans and dimethyl sulfide are the most common sources of odors in the solid waste arena. These compounds give off those commonly known odors that smell of rotten eggs, garlic, skunk, and rotten cabbage. These compounds are detected by the human nose at levels in the parts per billion resulting in foul odors at low concentrations.

The article goes on to highlight a number of odor control solutions, including OMI Industries’ Ecosorb®. Ideal for MRFs, this solution eliminates odors without the use of harsh or hazardous chemicals, expensive emission control systems, or masking fragrances. A proprietary blend of plant extracts, Ecosorb® is engineered to seek out and destroy organic and inorganic odors on a molecular level — safely and effectively neutralizing even the most persistent landfill odors.
