The site, located in the Roxbury neighborhood of Boston, has been in operation for more than 40 years.
"This addition to our portfolio exemplifies our strategy to build a vertically integrated renewable energy company. The UWM facility will increase ReEnergy's presence in the construction and demolition processing and recycling market in Eastern New England," said ReEnergy CEO Larry D. Richardson in a statement.
"In particular," he continued, the acquisition "will enhance our ability to recycle the C&D debris generated in the City of Boston, converting a significant percentage of the recovered wood into high-quality fuel that will be used to generate renewable energy."
ReEnergy operates eight renewable energy generation facilities in New England and northern New York State. The company also has two C&D debris wood processing facilities in Salem and Epping, N.H.
ReEnergy recovers an average of 70% of nearly 500,000 tons of C&D material it processes annually, the company said.
