EQT-backed Covanta, a provider of environmental services for businesses and communities across North America, completed the acquisition of SGS Recovery, a provider of waste management services, Frontier Fibers, a provider of fiber-based bedding products, and Buffalo Fuel, a provider of transportation and recycling service, from Santarosa Group, a holding company. Financial terms were not disclosed. "The addition of SGS Recovery, Frontier Fibers and Buffalo Fuel to our team is a game changer because it elevates Covanta into the leading provider of alternative fuels in the country. These are exciting early innings in our transformation as we lay the groundwork for more sustainable solutions to carbon intrusive industries. We look forward to this extraordinary opportunity to build upon compelling services that not just meet customers' economic needs, but also present effective solutions that shape a truly circular economy," Azeez Mohammed, Covanta President and CEO.
