I have actually just had a thought about trash. Back when I was a wannabe tree-hugger, I learned a lot about how much crap gets thrown away that doesn't really need to be: after recyclables are sorted out and organics are composted, there is practically nothing left to go in the bin. Newspapers, magazines, phone books, any glass, most sturdy plastics, cardboard, aluminium/tin cans are all recyclable; any extra paper can be saved as a fire-starter for when it's cold; any food that is meat- or dairy-free can go in the garden or, if necessary, in a plastic air-tight tub to cure until you can find someone who wants it, because it really doesn't smell (except for coffee grounds); meat trimmings can be given to pet cats or dogs, or fed to strays. If you take the time to set up a well-organised sorting system like the one I did a few years ago for my parents, this stuff becomes second-nature in no time (note: parents managed it). If there isn't a recycling service center* nearby, check and see if your work has one and totally dump your shit in with theirs, they won't care.
Now, I know that some places charge a lot for rubbish pickup and other places don't. My neighborhood charges $20 per month (my landlady pays this, along with the homeowner's association fee, because it's required by the neighborhood covenant), but my boyfriend's apartment complex covers it in the rent price so it's essentially free. Basically what I am getting at is that, unless you would have to make extra (costly) trips to the recycling center or pay for a pickup service for that instead, you could feasibly cancel your garbage service. It might only save you $5, but even then it's still another $5 you wouldn't have had.
Lots of places that are not near me, I think, also do that lovely "old-fashioned" practice of making deposits on things like glass bottles at stores, and you can get like 5˘ or something back on every empty item you return!
Plus, either way, you get to feel warm and fuzzy inside for being a good hippie.
*Make sure to do a little investigation into any purported "recycling" that garbage companies do. Companies in the south are pretty notorious for spreading word around that they pick up recycling as well as your rubbish, or they have separate dumpsters for recyclables and trash, and then they just dump it all into the same truck, which completely defeats the purpose.
