Clean Harbors disposes of hazardous waste — the kind that cannot simply be taken to a landfill.
A chemical plant, a refinery or a hospital has to put its solvents, sludges and contaminated soil somewhere. The company collects, treats and incinerates them in its own furnaces. Hazardous waste incinerators in the country number in single digits, and building a new one is close to impossible because of permitting — that is the main asset.
The second line is collecting used oil and re-refining it into base oil: the feedstock is cheap and the product sells at market price. Demand is steady, because waste is generated regardless of the cycle and regulatory requirements only tighten. Risks: base oil prices, the industrial cycle, environmental claims. The company pays no dividend.
