If your rubbish bin is filling up way too fast to be convenient, you can save space and money on bin liners by compressing your garbage. All you need is two large buckets of the same size.
Just toss some garbage into one, place the other on top, and sit down or jump on it to compress the contents. I'd definitely only do this outdoors, and I probably wouldn't do it with loose food scraps. But this is handy for those times when you have a lot of paper or packing supplies to get rid of.
