From KQED Science, find out how San Francisco’s 600 tons of compostable waste can be transformed into a dark, nutrient-rich material that will not only feed plants to improve the quality of what we eat and drink, but that also has the potential to offset America’s carbon emissions by over 20%. Above, agronomist Bob Shaffer takes us Inside the Compost Cycle.
