Harsco, a provider of industrial services and engineered products, has acquired Clean Earth, a provider of processing and beneficially re-using specialty waste, from Compass Group Diversified and certain other minority stockholders for $625m. “This acquisition is expected to create significant strategic and financial benefits for our shareholders and customers, including higher margin and recurring revenues, cost savings and potential cross-selling opportunities beyond what either company could achieve on its own. Clean Earth brings a proven management team and talented employees with a strong track-record of growth and environmental and safety performance.” Nick Grasberger, Harsco Chairman and CEO.
