Feb 8th – Avoid putting food waste down your kitchen sink garbage disposal (or at least, avoid certain items).

I always wondered if it is better to use the garbage disposal for food waste or put it in the trash.

Obviously, the best thing to do is compost the food, but if that is not possible, there is controversy over whether it is better to put the waste in your garbage disposal where it is added to the water supply or put it in the trash where it will remain in a landfill and produce methane.   The greater consensus I found was that you should put it in the trash before you add it to the water supply but there are legitimate arguments for both sides.   If you choose to use your garbage disposal, be sure to avoid these items due to the extra efforts/chemicals needed once it’s down the drain and on it’s way through the wastewater treatment facility:

  1. Grease
  2. Starchy or stringy vegetables
  3. Pasta
  4. Egg shells
  5. Rice
  6. Coffee Grounds
  7. Fruit pits or seeds
  8. Bones

Also, if you are using your garbage disposal, always use cold water.  It wastes energy using the heated water.
