I was watching the news the other day and saw a piece about garbage disposals and how in some cities they have banned the use of garbage disposals in homes to alleviate the strain on the sewer systems. As I read more about it, I found that its debatable, some say yes its bad in certain conditions and others say no, its not bad.
Why you should use a garbage disposal –
1. Leftovers from your disposal make their way to the waste water treatment plant and the stuff that gets separated from the water is either land-filled, condensed into fertilizer, or digested by microorganisms.
2. Trucking all that garbage to the landfill takes a considerable amount of energy.
3. The decomposition of your trash in the landfill will likely result in more damaging greenhouse gas emissions.
Why you should use the garbage can –
1. Evidence that the effluent that is pumped back into local water streams does affect their chemical composition and aquatic life.
2. You use a lot of water using a disposal.
3. You’ll be indirectly responsible for the extraction of the metal needed to make the disposal.
From Slate.com – Under normal circumstances, you should always compost if you can. Otherwise, go ahead and use your garbage disposal if the following conditions are met: First, make sure that your community isn’t running low on water. (To check your local status, click here.) Don’t put anything that is greasy or fatty in the disposal. And find out whether your local water-treatment plant captures methane to produce energy. If it doesn’t—and your local landfill does—you may be better off tossing those mashed potatoes in the trash.
