Overview

Back in 2002, San Francisco began giving away green bins for free home compost collection. Composting became mandatory in 2009 for all city residents. But the process of collecting and storing kitchen compost scraps for weekly pickup was messy. Many well-intending residents collected their home compost in plastic bags, which defeats the whole purpose. Others opted for backyard compost bins, compost tumblers, and worm composting, but those require constant maintenance and care. "There's got to be a better way!" thought Russ Cohn. The MIT-trained engineer and garage tinkerer vowed to find a better way to make compost.
