TEMPE - The apple cores, half-eaten sandwiches and other unappetizing scraps thrown out at Arizona State University's Barrett Dining Hall would usually end up in a landfill. Instead, it will become compost to grow gardens and trees.
Sarah Appleby, 19, writes down the weight of the bin that
Jessica Thompson, 21, is weighing. The two are part of the
University of Arizona Compost Cats, and they pick up scraps from
the Student Union and campus-area restaurants.
