Houston-based Waste Management has invested in Waltham, Mass.-based Harvest Power, a firm that builds and operates facilities that produce energy from organic waste. Waste Management did not reveal the amount of its investment.

“We want to extract more value from the materials we manage than anyone else in our industry through new and emerging processing and conversion technologies,” said Tim Cesarek, managing director of organic growth at Waste Management, in a press release. “Combining Waste Management's industry leadership and expertise in the collection and management of a wide range of segmented waste streams with Harvest's leading technologies and industry knowledge will be key to developing new, high value added end markets for organic materials and accelerating the growth of organics recycling across North America.”
