Superior Waste is a holding company formed by Red Dog in March 2022 to acquire and consolidate waste services providers in Oklahoma. Red Dog partnered with Billy Dietrich, a veteran of the environmental services industry, Monroe Capital, and Tom Pritzker’s family business interests (advised by The Pritzker Organization).
Superior Waste closed the following add-on acquisitions under Red Dog ownership: Shawnee, Oklahoma-based Central Disposal (March 2022); Tulsa, Oklahoma-based Harley Hollan Companies (September 2022); Vian and Eufaula, Oklahoma-based Sue’s Recycling and Sanitation (June 2024); and Shawnee, Oklahoma-based SDS Roll-off Dumpsters (March 2024).
GFL Environmental (NYSE: GFL) is a provider of waste management, infrastructure, and soil remediation services across Canada and the United States. Specific services include solid waste collection, landfill and transfer station operations, soil remediation, and liquid waste services under brands such as GFL Environmental and GFL Infrastructure.
Customers of GFL include residential households, commercial businesses, industrial operations, and municipalities. GFL Environmental was founded in 2007 by CEO Patrick Dovigi and is headquartered near Toronto in Vaughan, Ontario, Canada, with 400 facilities in all Canadian provinces and over 27 U.S. states.

The solid waste and environmental services sectors are undergoing accelerated consolidation as scale and geographic reach yield operational efficiencies and improved asset utilization. Mid-size platforms are increasingly being aggregated into larger networks, especially in regions still fragmented among local haulers. Meanwhile, pressure on environmental regulatory compliance, sustainability mandates, and recycling economics adds complexity and cost to operations. The strategic acquirer model remains potent in this space, capitalizing on synergies in logistics, landfill access, and cross-selling of services.



Monroe’s independent sponsor group provided both debt financing and equity co-investment to back Superior Waste’s expansion, enabling the company to pursue multiple add-on acquisitions. This group specializes in delivering flexible, “one-stop” capital—including both debt and equity co-investments—for acquisitions, mergers, growth initiatives, recapitalizations, and business combinations.
Monroe Capital (NASDAQ: MRCC) provides senior and junior debt financing to middle-market businesses with at least $3 million of EBITDA, special situation borrowers, and private equity sponsors. Investment types include unitranche financings; cash flow, asset-based, and enterprise value-based loans; and equity co-investments. Sectors of interest include healthcare, business services, technology, consumer, and niche manufacturing.

“We’ve partnered with Monroe across several of our portfolio companies,” said Mr. Chambers. “Their unique ability to provide debt and equity at scale allowed us to achieve a successful result on Superior.”
Stifel was the financial adviser to Superior on this transaction.
