Marty Metro, founder and CEO of UsedCardboardBoxes.com, returns to Green is Good to share his empowering story as a former struggling entrepreneur who now heads the premier marketplace for used boxes. What started as a grassroots operation going door to door to service new homeowners is now a buyer and reseller of packaging from some of the world’s most renowned Fortune 500 companies. Since its beginnings in 2005, UsedCardboardBoxes.com has saved more than 500,000 trees (and counting). “Nobody told businesses 100 years ago that they shouldn’t be cutting down trees — they thought it was a natural resource,” Metro says. “However, times have changed. We realized we don’t need to be cutting down more trees to make boxes. Why don’t we just use the boxes that we already have?”
