If you haven't got a compost bin in your garden, even if it is a very small garden, then you should definitely put a compost bin in your garden.
Put all of your 'organic' shit like peelings and 'tops & tails' into it, and watch it NEVER actually fill up. Keep feeding it more and more - watch it take more and more and still not be anywhere near even half full.
It's like fecking magic.
If you have enough space, plant something next to or near to it, and it will grow like a triffid, even if you have no use for the end product, a compost bin will eat everything you might otherwise throw elsewhere, and will free up space to chuck what can't be chucked any other way.
If you haven't already got a composter, you should definitely get one.
