Clean Harbors has acquired EnviroServe for $470 million, seller One Rock Capital Partners said on October 5. The announcement confirms that the previously disclosed sale is complete, moving the environmental-services business from private-equity ownership into another industry operator.
The Ohio connection is an operating footprint across Cincinnati, Cleveland, Columbus, North Canton and Toledo, all listed on EnviroServe’s official locations page. Its network handles environmental field services and waste collection, processing, recycling and disposal, alongside emergency response work.
EnviroServe’s services include site remediation, rail-related work and industrial cleaning. It also transports and processes both hazardous and non-hazardous waste, bringing a range of routine and emergency assignments into the buyer’s portfolio.
The seller said it had expanded the business through new locations, acquisitions and internal growth. Clean Harbors co-chief executive Mike Battles said the buyer plans to integrate EnviroServe and use the two businesses’ combined capabilities to serve customers across North America.
Clean Harbors already provides hazardous-waste management, spill response, industrial cleaning and recycling. Its operations include facilities for treating, disposing of and recycling waste, as well as field crews that perform cleanup work at customer sites. Those activities put the acquired business within the buyer’s existing environmental-services market.
The release does not announce Ohio hiring, layoffs or location changes. The $470 million is the price for the EnviroServe transaction as a whole, rather than a disclosed valuation of its Ohio operations.
