To omit odors from our garbage can inside the house, if we have anything that may start to smell after a day or so (examples: the styrofoam that meat comes on, banana peels, etc.), I simply put it in a plastic grocery bag and put that in my freezer. I add to that bag all week long if I have items that may start to smell before garbage day. I also scrape our dinner plates into this bag after meals.

I hate the way that rolls of trash bags get unrolled, so I found a great solution. I cut a small square hole in the top of the container with my jig saw, making a slot for the trash bags to "pop up" like they do on the baby wipe box.
