Casella Waste Systems is acquiring Mountain State Waste. The company offers residential, commercial and industrial waste collection services in West Virginia and parts of Ohio, Pennsylvania and Kentucky.
Casella expects the deal to generate approximately $30 million of annualized revenues. The transaction is expected to close in the fourth quarter, pending regulatory approvals.
The deal helps Casella expand into new territories for the company, as well as strengthen its footprint in Pennsylvania, where it already operates. CEO John Casella noted the deal especially helps position the company to expand in West Virginia.
“Mountain State Waste has excelled operating in the franchise markets of West Virginia and has built a strong reputation for reliable service and community engagement, and we look forward to building on that legacy,” he said in a statement.
Mountain State Waste has four hauling operations, as well as a fleet of about 60 vehicles, according to federal records. It also operates a transfer station in Mt. Morris, Pennsylvania.
Mountain State Waste, which pitches itself as a hauler that understands West Virginia’s “geographically challenging” environment, has spent the last few years expanding its presence in the region. In 2022, Mountain State Waste acquired Republic Services’ trash collection routes in West Virginia’s Lincoln, Mason, Boone and Logan counties. In May 2024, it acquired Greene Waste Services, a hauling company based in Greensboro, Pennsylvania. In December, it acquired B&M Sanitation in Ohio.
J.P. Phillips, vice president and co-founder of Mountain State Waste, will join Casella’s team “to help realize opportunities to further enhance service offerings, invest in infrastructure, and support the communities in the new markets we now serve,” John Casella said in the statement. He thanked Phillips, along with co-founder and CEO Randie Lawson, for their work building a successful company.
Company executives have previously said their M&A focus has largely been on densifying Casella’s existing footprint, establishing new markets adjacent to its current operations and growing its presence along the Eastern Seaboard. During the company’s Q1 earnings call, John Casella estimated an active M&A pipeline of about $500 million in revenue.
He also noted the company had completed four other acquisitions so far in 2025. That included Boston-based Save That Stuff, as well as deals filling in its service areas in Maryland, Pennsylvania and western New York.
