Clean Harbors, a provider of environmental and industrial services throughout North America, terminated the agreement to acquire the used motor oil and re-refinery assets from Vertex Energy, a specialty refiner of alternative feedstocks and marketer of high-purity petroleum products, for $140m. "Clean Harbors and Vertex have mutually agreed to terminate the transaction. We can now refocus our energy on other ways to deploy our capital, including continuing to invest in our Safety-Kleen Sustainability Solutions segment," Alan S. McKim, Clean Harbors Chairman and CEO.
