They’re a familiar sight in Johannesburg—a procession of people, usually men, balaclavas drawn over faces against the cold, hauling mountains of recyclable stuff on homemade trollies across the suburbs. Writer Tanya Zack and photographer Mark Lewis track several of these entrepreneurs, following them for miles from their homes in the city, to the lucrative dustbins of Parkwood, Melville and Windsor, to the waste depots, and back home. In Good Riddance, Zack and Lewis give us more stories about the people whose livelihoods form another important layer of the economic fabric of the city.
