Recycling programs in partnership with scavenger associations as a sustainability factor in Metropolitan São Paulo, Brazil

Abstract

The aim of this research was to evaluate waste recycling programs in partnership with scavenger associations in Metropolitan São Paulo, to verify their social, economic, sanitary, and environmental impacts in a sustainability perspective. Methods included bibliographical and data research and structured interviews with representatives of 39 municipalities. The analysis of factors responsible for program continuity was undertaken. It was found that among 39 municipalities, 23 (59%) have developed official recycling programs, 19 in partnership with scavenger associations. Indicators analysed showed that the programs resulted in social, and economic gains for scavengers, increased social capital and they contributed to the reduction of waste destined for landfills. However, there are competition factors that have been threatening the continuity of those programs.
