    Composting—Turning Garbage into Black Gold

    Forty percent of our food is wasted, but through composting, food waste can be turned into black gold—so called because compost, the mixture of decayed organic matter, is valuable as a nutrient-rich soil additive. In the United States, however, less than 3 percent of food waste is composted.
