A system for disinfecting and deodorizing garbage chutes using methane sensors at the top and/or bottom of the trash chute that includes an ozone generating unit at the bottom of the trash chute. The ozone-generating unit includes a flexible ozone distribution hose that emits ozone directly into the trash receptacle upon methane gases beginning to exceed the 50 parts per million threshold. Upon methane concentration levels reaching 50 parts per million, the ozone generator begins emitting ozone, the methane sensor continuously monitors ozone levels to ensure that there is no more residual methane left in the trash chute that exceeds a concentration of 50 parts per million. Optionally, the system can include an ozone sensor as a safety device to ensure that ozone levels do not surpass 0.09 parts per million.
