Your old phone could be a gold mine for the climate

What this episode covers

Drilling into the ground isn’t the only way to source metals for clean energy. You can also get them from castoff phones, laptops and TVs. It’s called urban mining. We speak with Maria Holuszko at UBC’s Urban Mining Innovation Centre about developing more efficient techniques for harvesting the gold, copper and other materials in old electronics. And Craig Wisehart of the Electronic Products Recycling Association takes us to a depot to find out how to drop off your old stuff and where it goes.
