Long Island Waste Services combines with National Waste Services

Long Island Waste Services (LIWS), a Islandia, New York-based Terramont Infrastructure Partners portfolio company, has completed a business combination transaction with National Waste Services (NWS), which provides waste and recycling services throughout Long Island. The combined company will operate under the Long Island Waste Services and National Waste Services names.

Formed in 2020, LIWS offers waste collection services and operates transfer stations as well as recycling facilities, recovering cardboard, paper, metals and construction materials. Through its service and attention to customer needs, LIWS has grown considerably, becoming one of Long Island’s leading companies in the commercial waste industry, according to Terramont, which made an equity investment in the company in late 2024.  

Founded in 2001 by the Leone family, NWS has a reputation as a dedicated full-service provider of collection, disposal and recycling services for commercial, municipal and residential customers, operating in a shared footprint with LIWS in Long Island’s Nassau and Suffolk counties.

Anthony Avellino, president and CEO, leads LIWS’ management team and has led the company’s growth and expansion, achieved partially through purchasing several other waste management service firms, over the previous five years. He will continue in his current role at the combined company.

“We have invested significant capital into the LIWS platform, which strongly positions the company for this truly transformative transaction,” Avellino says. “We’re excited to embark on LIWS’ next chapter as a combined company with NWS."

“The two companies share a similar commitment to their customers and the same ideals for company culture," NWS CEO Joseph Leone adds. "The NWS sales team and operations personnel will remain, ensuring the same high level of service that its customers have come to expect.”

Leone will join the company’s senior leadership team and, with his family members, retains an ownership stake in the combined company.

“We are delighted to support Anthony and the entire LIWS team in this milestone transaction," says Chris Pih, partner at Terramont. This combination exemplifies our shared strategic vision to build an industry-leading waste management platform through disciplined consolidation.”

Environmental Services Investors, a co-investor in LIWS, and its principal, Dickson Suit, served as advisor for LIWS. Comerica Bank, Tecum Capital Partners, Patriot Capital and Colbeck Capital provided debt financing for the transaction. Certilman Balin Adler & Hyman LLP served as legal counsel to LIWS; K&L Gates LLP served as legal counsel to Terramont; and Cole Schotz P.C. served as legal counsel to NWS.
