Superior Waste Industries, LLC (d/b/a Superior USA Waste), a Shawnee, OK-based environmental services holding company, completed its third acquisition by acquiring SDS Roll-Off Dumpsters (“SDS”), a solid waste management company offering commercial and residential roll-off collection services to customers across Central Oklahoma.  

“SDS is a perfect fit for us strategically as we continue our strategy of expanding and densifying within Oklahoma,” said Billy Dietrich, Chief Executive Officer of Superior USA Waste. He continued, “We are very impressed with what the SDS team has accomplished, and we are committed to delivering the same high-quality service to both existing and new customers.”

“It has been a pleasure working with Billy and the Superior USA Waste team, and it is evident they share our commitment to best-in-class customer service,” said Ira Romine, the owner of SDS. 

Superior USA Waste 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 provides debt financing for Superior USA Waste.  Superior USA Waste has significant growth capital at its disposal and is actively seeking acquisitions and development opportunities.
