Brazil is ranked as a world leader when it comes to aluminum can recycling, though for its catadores—the independent pickers who collect those cans from city streets—making a living from the work isn't easy. But a project in São Paulo could give them another stream of revenue—by turning some of their collected aluminum cans into sellable merchandise.
Can City is a mobile foundry operating on the streets of São Paulo. Free waste cooking oil, collected from local cafés, powers a furnace that melts the cans. The liquefied aluminum is poured into molds to create products that can be sold.
