Brazil. Sao Paulo state. Sao Paulo. 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. A worker from the centre sort outs the empty bottles. © 1994 Didier Ruef .
