Founded 43 years ago and headquartered in Boston, Clean Harbors generates over $5.2 billion in revenue, primarily serving North America. Their core mission revolves around environmental stewardship: collecting and safely processing hazardous waste generated by various industries, including pharmaceuticals and manufacturing, to ensure minimal environmental impact.
Despite their significant footprint—avoiding 5.2 million metric tons of greenhouse gases annually—most people outside their industry remain unaware of their existence. This quiet yet vital work underscores a core principle: excellent environmental practices often operate behind the scenes, driven by technologies that need not always be in the limelight.
