-Phoenix: Recycled City is a pickup service for residents and small businesses. They set you up with a bin for corralling kitchen waste, which they then pick up - and you can choose to donate your soil to local farms and gardens, or take it back for your own use in your yard at home. They also keep a list of local restaurants who compost - take a look here if you'd like to support those local businesses!
