Clean Harbors (CLH) Stock Analysis & Winston Score

Clean Harbors helps businesses safely get rid of dangerous waste. This includes things like toxic chemicals, contaminated soil, and used motor oil. Their customers are factories, hospitals, oil companies, and government agencies — basically anyone who produces hazardous materials that cannot simply be thrown in a regular trash bin. The company makes money by charging fees to collect, transport, treat, and dispose of hazardous waste. It also runs a large used oil re-refining business under the Safety-Kleen brand, turning waste oil back into usable lubricants. Clean Harbors operates mainly across North America, with hundreds of facilities in the United States and Canada, making it one of the largest hazardous waste companies on the continent. Its network of permitted disposal facilities is hard to replicate because getting government approval to build new hazardous waste sites takes years, which protects it from new competitors. The key growth driver is increasing environmental regulation, though a slowdown in industrial activity could reduce the volume of waste its customers generate.
