Superior Waste Industries, LLC (d/b/a Superior USA Waste), a Shawnee, OK-based environmental services holding company, completed its first acquisition by acquiring Central Disposal, a fully-integrated solid waste management company offering residential and commercial collection services, industrial / construction roll-off services, and recycling, a transfer station in Shawnee, and disposal at its CenterPoint landfill in Prague, OK. Superior is led by Billy Dietrich, a waste industry veteran with over 25 years of experience at leading environmental services companies such as Superior Services / Onyx North America and Deffenbaugh Industries. “Superior’s mission is built around the idea of ‘local people serving local people,’” said Billy Dietrich, Superior’s CEO. Dietrich continued, “We don’t want to be just another waste company providing service to local communities from afar. Central will continue to be run by the founding family who truly know the market and their customers’ needs.”

“I’ve known Billy for a long time, and it was an easy decision to sell to Superior [Waste USA],” said Mike Adcock, the founder of Central Disposal. Adcock added, “He did everything he promised to do, and I know Superior will be a great home for the business my family and I built.” The Adcock family made a significant investment in Superior as part of the transaction, and Mike’s sons, Jon-Mark and Todd Adcock, will continue to run the Central Disposal and CenterPoint operations.

Superior intends to be the “partner of choice” for waste industry entrepreneurs seeking growth capital or to transition their businesses. Superior partnered with Red Dog Equity LLC, an Atlanta-based private equity firm, which, through its partnership with Monroe Capital and Tom Pritzker’s family business interests (advised by The Pritzker Organization), has additional equity capital available to fund Superior’s future acquisitions. Monroe Capital also provided debt financing and an acquisition facility to Superior.
