The Raw Materials Hidden in Our Cities - Gareth Byatt

We recycle steel. We're rather good at it. But recycling isn't the same as reuse, and that gap is quietly costing us. 

In the latest episode of the Responsible Raw Materials podcast, engineer Gareth Byatt makes the case with a simple question: can a steel beam simply remain a steel beam? Today, when a building comes down, we crush much of it, downcycling steel into low-grade rebar and burying valuable niobium, copper and nickel along with it. The materials survive, but their value doesn't. 

Gareth's argument is that reuse has to be designed in from the very start. If we only ask what we can recover once the demolition crew arrives, most of the important decisions have already been made. He also reframes our towns and cities as mines in their own right, full of steel, copper and concrete we've already paid to extract. 

What would our cities look like if we designed every building to be taken apart?
