Hamilton's link in the aluminum supply chain
Many people pass Hamilton's east-end industrial lands without knowing what happens there. One facility takes a by-product of steelmaking and turns it into materials that much of modern industry depends on.
When coal is processed into coke for steel production, it releases coal tar. Rather than treating it as waste, this facility distills it, much as a refinery separates crude oil, into a range of usable products.
The most important is coal tar pitch, which serves as the binder in the carbon anodes used to smelt aluminum. That aluminum goes on to become vehicles, aircraft, beverage cans, and power lines.
The remaining fractions are used in adhesives, tire rubber, construction materials, wood preservation, and specialty chemicals. Hamilton is also now home to research into adapting this carbon chemistry for lithium-ion battery materials.
It's a reminder that Hamilton's industrial story extends well beyond steel itself.
