I wash the plastic storage, freezer, sandwich bags and sealer bags and reuse them unless they have had meat/fish or something rotten in them.

If I use foil on top of something, I keep it and wrap the leftovers up in it. This is usually meat like a roast. Or if I use foil for something and it doesn't get dirty at all I keep it and try and use it for something else.

I rarely use paper towels. I keep a dishcloth beside the sink and use it to wipe the counter, wipe out the sink etc.
