Rumpke is a privately owned waste collection and recycling company headquartered in Colerain Township, Ohio. Founded in 1932 as a small junkyard and coal delivery operation, it has grown over three generations into one of the largest privately held waste and recycling companies in the United States, employing more than 2,500 people across Ohio, Indiana, Kentucky, West Virginia, and Illinois.
The company's core operations include curbside residential waste and recycling collection, recycling facility operations using single-stream (commingled) processing technology, and broader sustainability and materials recycling initiatives. Drivers completing residential routes typically make 400–600 stops per day. In 2025, Rumpke recycled over 1.4 billion pounds of materials across its service area.
As a third-generation family business, Rumpke operates with a culture centred on safety, teamwork, environmental stewardship, and employee development. The structure of a privately owned company means decision-making remains close to the operational level, and the organisation places explicit emphasis on employees being part of a close-knit team working toward a shared purpose.
