Our Leadership Team
Marty Metro, Founder / CEO, is an entrepreneurial trailblazer with an unyielding “if at first you don’t succeed” spirit. In 2002, well before the environmental movement took off as we know it, Marty launched Boomerang Boxes, a chain of eco-friendly retail stores that bought/sold USED moving boxes… But just 3 years in, it became clear his attempt was premature, undercapitalized and riddled with logistic flaws. In short, it was simply not “sustainable”.
Devastated but not discouraged, Metro took a “day job” as a technology consultant (leveraging his then-outdated knowledge of SAP) and spent nights and weekends rehashing his mistakes. After revising the business plan, raising capital, and launching a scalable, tech-centric model – UsedCardboardBoxes.com grew to a national reuse logistics firm working with many of the largest, most trusted companies in the country.
Entrepreneur Magazine featured Metro and in an article entitled:
“From Business Failure to Multimillion-Dollar ‘Green’ Niche“
Metro and his team leveraged the knowledge, experience and technology they had created over the years, to tackle ALL solid waste, via UCBZeroWaste. This new asset-light company is a waste reduction firm that helps its clients manage ALL commodities, ALL vendors, ALL logistics, ALL monthly invoicing and ALL reporting, using its own proprietary software called WATER (Waste Analytics & Tracking for Environmental Reporting). UCBZeroWaste’s program and software are now used by some of the largest, most recognizable brands in the country, including McCormick Spice (#14 Most Sustainable Corporation and #1 in Food).
Additions to the portfolio include both UCBPalletSolutions and UCBOrganicWaste… and UCBEnvironmental was created to manage and support all of these offerings.
Metro graduated Cum Laude from the University of Maryland and holds an MBA in Information Systems & Management from the University of Arizona, before beginning his career as a SAP consultant with Andersen Consulting (now Accenture).
