Fourteen years ago, Blanca Cecilia Lopez began combing the streets of [Bogota, Colombia] in search of sellable articles to feed her family. She typically earned only a few dollars a day scavenging bottles, cans, paper and any other reusable items that she could find. Two years ago, however, her life changed dramatically thanks to a grassroots organization that found her a position at a city recycling center with a monthly salary and health benefits. The 50-year-old mother of seven owes her new life to Nohra Padilla, who began organizing waste pickers like Lopez in 1990 into the Bogota Recyclers' Association. For her work, Padilla is one of six recipients of the [2013] Goldman Environmental Prize. Over the years, the association, which has 2,000 members, has battled city officials and private sanitation companies vying to monopolize trash collection from Bogota's 8 million inhabitants. In the 1980s and 1990s, Padilla and other organizers were threatened by right-wing paramilitaries who regarded organizing the poor as subversive. Several waste pickers were murdered in what the militias called social cleansing." A talent for organizing and motivating others emerged, turning Padilla into a leader of an estimated 17,000 waste pickers who are a common sight on Bogota streets pushing hand carts or riding on horse carts piled high with scavenged trash. "If she (Padilla) weren't around, the recyclers would have to compete with the big trash companies," said Federico Parra, regional coordinator for a global nonprofit that helps improve conditions for the working poor.
