TerraCycle’s business model  follows the age-old refrain: one person’s trash is another’s treasure.  The company has collected millions of used bottles, cereal boxes and  packages, and has converted these materials into shopping bags,  backpacks, watches, and pencil pouches. In all, TerraCycle offers more  than 150 products to consumers via large retailers like Target,  Wal-Mart, OfficeMax, Whole Foods, and The Home Depot. In 2009, the  company reported $7.6 million in revenue and its projection for 2010 is  double that. Its number of employees also increased to 75 in 2009 from  50 in 2008.
