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.
AGU25, the premier Earth and space science conference, takes place December 15-19, 2025 in New Orleans, Louisiana. This year’s theme—Where Science Connects Us—puts in focus how science depends on connection, from the lab to the field to the ballot box. Once again, Lamont-Doherty Earth Observatory and Columbia Climate School scientists, experts, students, and educators are playing an active role, sharing our research and helping shape the future of our planet. #AGU25 Learn More
