As many great companies do, this one started in a dorm room. Yet the light-bulb idea that emerged from these tight living quarters was... collecting trash? TerraCycle, founded by Tom Szaky, is a company that "upcycles" waste into affordable, eco-friendly products ranging from worm-waste fertilizer to messenger bags and school supplies. A company that has mobilized over 10 million people to collect trash, diverted over 1.9 billion units of waste from landfills, boasted a revenue of $7.5 million, and donated $1 billion to schools and nonprofits, TerraCycle’s road to success was a result of hard work, persistence, and the courage to take risks. A college drop-out with nothing but a firm belief in his vision, Szaky recalls, "In those early days, no one returned my phone calls. I would literally be laughed at when I tried to call retailers to sell them my fertilizer." But today, nothing is impossible. Szaky resolves, "I hope in five years from now there will be a TerraCycle upcycling bin in every school, church, and retail location in America!"
