The City of Tucson's FoodCycle Program is a full-service composting program operated by Environmental Services in partnership with the University of Arizona Compost Cats and the San Xavier Co-op Farm.

The University of Arizona Compost Cats is a student-operated program that works to divert food waste, manure and other organic materials from local landfills and transforms them into high-quality compost for local agriculture and landscaping use.

Tank’s Green Stuff is a locally produced organic compost product made from landscape trimmings (green waste) that would otherwise go to the landfill.
