Recycling is great, but that's not exactly what I'm thinking about. Before you recycle or throw something away, decide if it might have a second life somewhere else. The bag your bread and bagels came in will go in the garbage eventually, so why not use it for your dog's next walk?
You can use the containers sour cream or cottage cheese came in to freeze things in. I also fill water bottles again and put then in the freezer -- your freezer will run more efficiently when full and when you need the space, you can thaw the bottle and use it to water plants.
Even the baking soda that's used to keep your fridge fresh can be used elsewhere. Put it in your garbage disposal, then pour some vinegar down and cover it with the drain stop. An hour later, run the water. This will keep your disposal odor free.
So before you toss something, think about if you can use it again. If not, check your local ordinances to see if it can be recycled.
