Brazil. Sao Paulo state. Sao Paulo. Two young boys and a wheelbarrow full of plastic to sell at "El Gringo". The "catadores" are men who collect paper, metals, bottles ... in order to sell these items as recycled materials and make a living. "El Gringo" is a buy-off center. Every day, it buys these recycled products to hundreds of men, all waste collectors, then resells them to various industrial factories. © 1994 Didier Ruef ..
