TerraCycle  has gotten a lot of media attention for its unusual business model: Basically, it takes waste and turns it into a wide range of products, from fertilizer to computer bags to kites. Co-founded by Tom Szaky, who dropped out of Princeton University to start the company, TerraCycle, which is based in Trenton, N.J., has been the subject of an Inc. magazine  cover story, a National Geographic reality show, and a recent profile in the Wall Street Journal. But in 2009, the privately held company says it lost $2.2 million on sales of $7.6 million. The problem, according to Mr. Szaky, TerraCycle’s chief executive, was that the company didn’t really know how to manufacture its many products. You can find out how he addressed the problem — and why he’s projecting a $3.2 million profit on sales of $16 million in 2010 — by watching the video below.
