Tom Szaky is the young CEO of TerraCycle, a liquid, organic plant food that comes in a spray bottle and works wonders feeding plants and making them grow. What makes TerraCycle unique is that it is garbage wrapped in garbage. The packaging is recycled plastic soda bottles rescued from the waste stream, and the plant food is worm poop. In 2003, Szaky and Jon Beyer entered the Carrot Capital business plan contest, which involved dozens of America's top universities and offered $1 million in seed capital to the winning team. Szaky likes to call it guerrilla marketing: using free media coverage, school outreach campaigns, and word-of-mouth promotion based on the effectiveness of the product. TerraCycle has also innovated in the way they obtain their packaging. They encourage schools, community groups and yoga studios to collect used soda bottles for them. But judging from the smarts and high-voltage energy of CEO Tom Szaky not to mention the success of the product.
