Investopedia: Clean Harbors Goes Back To Its Roots In A Big Way
Clean Harbors (NYSE:CLH)
is an interesting company. Built around hazardous waste collection and
disposal, the company remains a leader when it comes to these services,
but perhaps not as many investors are aware of how it has also built a
large oil and gas services business (largely through acquisitions). At the end of October, however, the company took a big step back to its roots in announcing the acquisition of Safety-Kleen.
