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.

Waste food, used teabags, coffee grounds and so on can be placed in a sealed biodegradable bag and frozen. The food won't decompose, so won't taint other freezer contents, nor will your kitchen or bins smell.
With prices now so high, this idea is not only frugal but also helps to save our land fills and helps to organize the trash. Of course I reuse my Ziploc bags over and over after rewashing them several times.
If you don't want your discarded food remains to sit in your trash can, and more than likely turn foul smelling, pop them into a plastic bag and freeze them until you put your trash bins out at the curb for your pick up.
Save money and use less trash bags. I try to flatten boxes that cereal, cake mix, crackers, etc. come in. This way I can get more trash in the trash bag before it needs replaced.
