Odor-Control You want to avoid nooks and crannies where waste can collect. At HDR we specify heavy-duty concrete floors and we prefer tall, reinforced concrete push walls. We also like to keep the building structure outside the walls so you don’t have columns and structural members creating places for trash to collect. If the client can afford it, we recommend interior liner panels…so dust and particulate material can easily be hosed down. In the pit there has to be easy access in and around scales; the design of the hopper above the truck should keep spillage to a minimum, and in the driveway lanes we typically call for curbs that guide the trucks and keep them where they’re supposed to be. Our experts have done tests of air being exhausted through roof fans, and the conclusion is that if the facility is operated the way it was intended to be operated, you generally won’t have an odor problem.” “The key,” says Egosi, “is a building that’s sufficiently large that you can receive and process the waste, where the trucks can get in and out quickly and where you can close the doors. Keeping the waste confined is important; [so is] putting it where it was designed to be put because that’s what the ventilation system is designed to handle. Storing waste in a building where it wasn’t intended to be stored usually occurs when facilities begin handling more material than they were designed for, something decision-makers need to consider. One thing I like to recommend is that transfer stations install high-speed roll-up doors. Even though a permit may call for keeping entry and exit doors closed, because it takes too long to open and close a conventional door, many operators keep their doors open whether they’re receiving a load or not. But an open door is a source of odor.” Another option for transfer station drag-out fumes is a door perimeter system being marketing by Hinsilblon Ltd.
