Why Do We Use Ozone? Compostable materials are brought to two large dumpsters in the Buntrock Trash Room. When these dumpsters are full the materials are hauled off site for processing. To control/eliminate odors made by the decaying food materials, ozone gas is pumped into the two dumpsters (in simple terms the ozone molecules react instantly with the odor-causing molecules; this eliminates the “garbage” smell and also destroys the ozone molecules).
To ensure that ozone levels remain at a safe level in the Trash Room, the ozone generator is controlled by a sensor.
- If ozone levels approach the OSHA 8-hour Permissible Exposure Limit of 0.1 ppm then the sensor automatically turns off the ozone generator.
- Therefore, individuals who enter the Trash Room are never exposed to harmful levels of ozone.
- It is important to note that humans can smell ozone at levels (0.03 ppm) far below the OSHA limit of 0.1 ppm.
The ozone sensor is located between the two dumpsters, above the large white metal box that says “Sonozaire Odor Neutralizer.”
