Eighty percent of drinks walk out of Starbucks stores. An astonishing 3 billion of the 200 billion-plus paper cups thrown into US dumps each year bear its familiar green logo.

This lofty-yet-laudable goal has led Starbucks to move from solo redesign efforts to enlisting paper mills, NGOs, and municipal governments to help. Getting more cups out of the waste stream and into places like composting service Cedar Grove, though, has proven to be a lot more complicated than expected. "Think about it," writes Anya Kamenetz.
