Whoops...forgot about garbage/trash collection.
1 can (UK "bin", yes?) of garbage per week might cost $5.
2 cans would cost maybe $12.
3 cans perhaps $25.
You are encouraged to recycle instead of creating non-recyclable garbage. We actually get a (very small) rebate on our trash collection from putting out recyclable materials separately.

A pessimist sees the glass as half empty.
A realist drinks it no matter how much there is.
