Waltham, Mass.-based Harvest Power, a firm that builds and operates facilities that produce energy from food waste and yard waste, has raised nearly $52 million in financing.

London-based Generation Investment Management, a company co-founded by former Vice President Al Gore, led the round of financing. DAG Ventures and Keating Capital also contributed, as did four companies that have previously invested in Harvest Power: Kleiner Perkins, Munich Venture Partners, TriplePoint Capital and Waste Management.

“Investors recognize our platform as the smart, cost-effective choice for managing organic waste,” said Paul Sellew, CEO of Harvest Power, in a press release. “Communities trust us to carry their organic management plans forward and provide local renewable energy and nutrient-rich soil amendments with disposal costs lower than landfills.”
