Brazil: Jardim Gramacho, Rio’s wasteland
Jardim Gramacho, on the edge of Rio de Janeiro, is the largest landfill in Latin America. But with the UN Summit on Sustainable Development coming to town, it's finally shutting down after 30 years. That means the end of an era for thousands of "catadores" who make their living sorting through the trash - they’ll have to move on. But its closure heralds the dawn of a new age in Rio: separating garbage and recycling it.
