Momentum Environmental acquires The Environmental Service Group

Momentum Environmental LLC, a Bath, New York-based provider of environmental and industrial services, has announced the acquisition of certain assets of The Environmental Service Group (ESG), American Recyclers Co. and Genesee Soil Recycling.

The acquisition, completed in partnership with ESG President Nicholas Halliday, expands Momentum’s capabilities and operational presence in western New York and supports the company’s broader growth strategy in contiguous geographies, Momentum says.

“ESG represents everything we look for in a partner—deep expertise, operational strength and a commitment to service,” says Bill Hunter, CEO of Momentum. “By uniting our teams and capabilities, we’re expanding the scale, sophistication and speed of the solutions we offer to our customers in our core operating geography.”

This transaction marks Momentum’s third acquisition since 2024. The investment advances the company’s goal of building a robust and scalable regional platform for environmental services and increases its territorial reach and adds operational capacity to better serve industrial and commercial clients in New York, Momentum says.

With this acquisition, Momentum now operates three New York State Department of Environmental Conservation-permitted waste processing facilities and maintains five branch locations in Bath, Lancaster, Rochester, Syracuse and Tonawanda, New York.

Founded in 2003 and headquartered near Buffalo, New York, ESG is an environmental services provider specializing in waste processing and environmental services. Its client base spans both public and private sectors and includes long-standing relationships with manufacturers, environmental service providers, engineering firms, municipalities and general contractors involved in transportation, energy and infrastructure development.

As part of the acquisition, Halliday will serve as senior vice president of Momentum. In this role, Halliday, now a shareholder in Momentum, will support integration efforts and help lead strategic initiatives to enhance Momentum’s environmental service offerings, the company says.

“Partnering with Momentum enables ESG to offer more than ever before,” Halliday says. “Together, we’re delivering a broader, more integrated environmental services experience, driving meaningful value for our customers.”

Momentum is backed by Nonantum Capital Partners, a Boston-based middle-market private equity firm. Momentum’s growth strategy includes additional acquisitions and the development of permitted waste processing assets to build a best-in-class environmental services company.
