OAKLEAF Waste Management is in the garbage business, but the firm rarely gets its hands dirty. The company manages waste disposal contracts for customers at more than 90,000 locations, specializing in industries such as hospitality, retail, property management, construction, and health care. To help its customers, OAKLEAF installs trash compactors to reduce the volume of waste and arranges for waste collection and recycling services. The company oversees waste disposal services through a network of 2,500 OAKLEAF-certified trash haulers at more than 100,000 customer locations in the US and Canada. The company was sold by New Mountain Capital to Waste Management in 2011 for $425 million.
