In my city (Italy) composting is mandatory (i.e. you might get fined if you an inspector discovers you put too much of it in generic waste bins). We have separate brown bins for curbside picking. It's simple to separate organic matter from non-organic matter, and reduces how much waste ends up in landfills. You can pick up bags of compost from the municipal utility, and you can then use it as mulch.
