Brazil. Sao Paulo state. Sao Paulo. The "catadores" are men who collect paper,... 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. Two workers are sorting, carrying and loading reccycled paper materials. © 1994 Didier Ruef ..
