Waste Dive has tracked more than 100 mergers and acquisitions in the MSW and environmental services sector this year, with dealmaking continuing in October. Publicly traded companies and those backed by private investors disclosed several deals over the last month.
Publicly traded companies
Republic Services acquired Queen City Disposal, a family-owned hauler in the Springfield, Missouri, area, the Springfield News-Leader reported. The local hauler provides residential and commercial waste and recycling services, as well as roll-off containers.
GFL Environmental acquired Wisconsin-based Big Hook Trucking & Disposal in October, a provider of residential and commercial dumpster rental services in La Crosse, Vernon and other nearby counties. Local officials expressed concerns that this could reduce volumes at the Vernon County Landfill, according to the Vernon Reporter. GFL is expected to now route volumes through a local transfer station to one of its own landfills in the state.
GFL also acquired Texas-based Four Seasons Disposal, a provider of roll-off and commercial service in the San Antonio area. The company had eight vehicles as of 2025, according to federal records. GFL’s presence in the area expanded earlier this year with the purchase of Frontier Waste Solutions.
Casella Waste Systems acquired Maine-based Dave’s Disposal, according to The Lincoln County News and a notice to customers. The small hauler was founded in 2024, offering a range of residential and commercial services in the state’s Mid-Coast region.
Finally, Clean Harbors in October completed two transactions to acquire EnviroServe and ES&H.
In August, the company announced a $470 million deal to acquire EnviroServe from private equity firm One Rock Capital Partners. It announced the $305 million deal to acquire ES&H in July as part of its second quarter earnings release. The deals are expected to bolster Clean Harbors’ emergency and field services and add combined annual revenues of $340 million.
Private equity-backed deals
Blue Castle Waste Solutions announced its formation through the acquisition of multiple companies: Lee’s Sanitation in Minnesota; and Carter-Miller Trash Service and Bridge City and Commercial Sanitation in Iowa. Blue Castle is a portfolio company of private equity firm Blue Sage Capital.
Meridian Waste acquired select assets from Virginia-based Lafferty Disposal, a residential collection company. The assets will integrate into Meridian’s Lunenburg Hauling and Lunenburg Landfill operations in southern Virginia. Meridian is backed by Warren Equity Partners.
GreenWaste acquired Certified Blue Recycling, which operates a recycling and waste transfer station in San Leandro, California. The facility accepts C&D, carpet and other materials. GreenWaste is a portfolio company of Macquarie Asset Management.
Biogas M&A deals
Divert acquired two anaerobic digesters from Anaergia, Waste Dive confirmed in October. The Rhode Island Bioenergy Facility is described as the largest of its kind in New England and can produce RNG. The Charlotte Bioenergy Facility, in North Carolina, is also substantial but has been idle since 2024.
Vanguard Renewables acquired Generate Upcycle’s five anaerobic digestion facilities in New York and Ontario. The deal will add an estimated 565,000 tons of processing capacity and 1.1 billion cubic feet of renewable natural gas production to Vanguard’s operations. Vanguard is a portfolio company of BlackRock.
In another biogas deal, Berq RNG announced a deal to acquire the Rialto Bioenergy Facility in California from Sevana Bioenergy. The deal also includes a pipeline of dairy and swine manure RNG development projects in Idaho, California, and Kansas, per a news release. The Rialto facility was built by Anaergia in 2020, but struggled and was placed into Chapter 11 bankruptcy proceedings in 2023. Sevana acquired the facility in 2024 for $20 million.
