About Us
ReEnergy Holdings LLC is a company dedicated to environmental sustainability that owns assets in the renewable energy sector and the waste and recycling industry. Its mission is to optimize the recovery of materials from construction and demolition waste and to generate biobased energy and products while prioritizing workplace health and safety.
ReEnergy Holdings was formed in 2008 by a senior management team comprised of experienced industry professionals along with an energy-sector focused private equity fund. In 2019, the management team completed a buyout of this fund’s ownership interest.
Primary Holdings
ReEnergy’s primary holdings are ReSource Waste Services LLC, which operates facilities in New England that recycle construction and demolition waste materials, and ReEnergy Biomass Operations LLC, which owns and operates bioenergy facilities that utilize forest-derived, sustainably harvested woody biomass and other waste residues to produce renewable clean energy.
In overseeing its two divisions, ReEnergy Holdings stresses:
Health & Safety
Environmental Compliance & Sustainability
Positive Community Engagement
Renewable Energy Projects
ReEnergy Biomass Operations owns and operates bioenergy projects in the eastern United States, utilizing sustainably harvested forest and agricultural residue to generate renewable electricity and steam.
In June 2021, ReEnergy Biomass Operations entered into a joint venture with Ember Infrastructure to create ReGenerate Energy, an industry-leading bioenergy platform. ReGenerate currently owns 137 MWs of operating biomass power generation across three facilities, including Albany Green Energy in Georgia and ReEnergy Stratton and ReEnergy Livermore Falls, both located in Maine.
ReEnergy Biomass Operations also owns and operates a 60-MW facility, ReEnergy Black River, that is located inside the fence at Fort Drum, the U.S. Army installation located outside Watertown, NY.

Recycling Facilities
ReSource Waste Services, New England’s largest processor of construction and demolition (C&D) material, operates an integrated network of strategically located facilities that process a wide variety of waste material and recover a high percentage of that material into high-quality end products for reuse. The company is committed to its mission to reduce the volume of waste that otherwise would be sent to landfills, improving the region’s environment and economy.
In November 2021, GCM Grosvenor, a leading global alternative asset management solutions provider, acquired a majority ownership stake in ReSource Waste Services. GCM Grosvenor’s investment, as well as its expertise as a leading infrastructure investor, is expected to propel ReSource and its team into a new stage of growth, allowing it to continue to expand its network and provide world-class services to an even greater number of customers throughout the region.
