A private equity firm has invested in medical waste company Curtis Bay Energy.

The Buffalo, N.Y.-based Summer Street Capital III L.P. invested an undisclosed amount in Baltimore-based Curtis Bay Energy, which provides regulated medical waste disposal (RMW) services to hospitals and health care providers in the East Coast Region, Summer Street said in a news release.
“This partnership with Summer Street will further enhance Curtis Bay Energy’s strong capital position, enabling us to accelerate our growth plans,” said Steven Groenke, Curtis Bay president and CEO. “We’re actively evaluating opportunities for external expansion in the RMW market, even as we invest in our infrastructure and service offerings.” Curtis Bay employs 82.

Summer Street looks to continue to invest in the RMW industry, which complements its presence in solid waste disposal. The company recently acquired Apple Valley Waste, which provides solid waste collection, recycling and disposal services for Berkley and Jefferson Counties in West Virginia and Washington County, Md.
