 The program came out of the University of Arizona's Compost Cats, as did the person who heads it up, Jose Garcia of the city's Environmental and General Services Department. Composting isn't new to Tucson. There's so many grassroots, local gardens, community gardens, school gardens that have been doing composting in a small scale. The University of Arizona Compost Cats started their compost facility in 2013, I believe, at the San Javier Co-op Farm.
