Brazil. Sao Paulo state. Sao Paulo. "El Gringo" is a buy-off center for recycled materials sold by the "catadores" who are men collecting paper, metals, bottles ... in order to sell these items as recycled materials and make a living. Every day, "El Gringo" buys these recycled products to hundreds of men, all waste collectors, then resells them to various industrial factories. A worker unloads the paper and carboards from a cart. © 1994 Didier Ruef ..
