End the Odor

Bad odors often elicit gnarled faces, loud incomprehensible reactions, and even gagging. This is because we are created in such a way to instinctively react to things we should avoid. Garbage, and specifically food waste, provokes this reaction because the decay of organic material results in emissions such as ammonia, sulfides, mercaptans, and butyric acid, as well as bioaerosols. Both types of emissions are to be avoided, because there are potential health implications from exposure to either of them.

Ew! What’s That Smell?

Decay of organic material requires microorganisms like bacteria to convert complex molecules and break them down into simpler ones like carbon dioxide and water. Unfortunately, during the process of decay, some malodorous chemicals from the garbage bin are telling us that not only should we have gotten rid of that rancid stuff sooner, but also that there are potentially harmful bacteria lurking in there!

Recent research from Open University in the UK investigated the release of bioaerosols from trash and revealed that after four weeks, bacteria types increase, resulting in the release of higher levels of endotoxins. The research did not indicate a significant increase earlier than two weeks. While the authors mention more study is needed, they also recommend conducting risk assessments for waste collectors since there is a known dose response relationship for endotoxins.

A few cities in the U.S.A. recently started biweekly trash pick-up. However, putrescible waste must be collected weekly, so where cities invest in green bin programs to collect organics, they can justify less frequent, biweekly trash pick-up. Nevertheless, it is not a good idea to let your organics stay in the trash for a lengthy time. Most everyone has experienced the smell of rotten garbage in much less time than two weeks. That being said, most trash is picked up much more frequently than every four weeks, but if you want to end the odors, why not avoid bioaerosols or endotoxins altogether and use your garbage disposer!
