This video tells the story of making compost on an industrial scale. Making compost is a relatively simple process even when you start with over a million tons of debris. Take 30 parts carbon (usually brown material) and 1 part nitrogen (usually green material), mix with water, air and time. The microbes will do the rest.

Thanks to Will Bakx and Sonoma Compost for sharing this process with Celebrate Sonoma!
