May 2: Safety-Kleen, a subsidiary of Clean Harbors, has acquired Noble Oil Recycling in an all-cash transaction. Financial terms of the transaction were not disclosed. North Carolina-based Noble Oil is one of the largest privately held companies that offers used oil recycling and re-refining services in the U.S. It operates in 12 Eastern states, according to a news release.

Founder Jim Noble, who started the company more than 40 years ago, died in 2023. His wife, Carol Anne Noble, said the sale to Safety-Kleen was the right move for the company’s employees, suppliers and customers. “We are very confident Safety-Kleen is the right company to carry on my husband’s legacy of quality service, fair dealing, and family values,” she said in a statement. A.E. Rosica & Co. advised Noble in the transaction.

Other recent deals include Meridian Waste acquiring North Carolina-based Tin Cans and WM acquiring Minnesota-based Hometown Haulers.
