Cities are already a major source of raw materials, recycling more than 400 million tonnes a year of paper and metal from their urban ore. In some particularly good countries more than 90 percent of their discarded aluminum cans are ‘mined’ and recycled into new aluminum. In a few cities, old landfills have even been mined to recover past discarded metals. Another link between cities and the mining industry might be replicating contests held by two important mining companies.
