Barriers and opportunities for waste pickers within solid waste management policy in Colombia.

• Low- and middle-income countries are characterized by the presence of waste pickers. • Few studies deal with traditional waste pickers' role and their formalization. • We analyze the transition into formality of waste picker organizations in Colombia. • Results from a national survey of individual waste pickers and recycling firms. • The second source was information analysis from workshops with waste picker leaders. • We report barriers and opportunities for waste pickers and their organizations. Low- and middle-income countries are lagging in research related to waste management initiatives and practices involving the informal sector and the problems faced by this population. Many case studies focus on waste management, but few deal with waste pickers' role and their formalisation process. In particular, there is a need to document the opportunities and barriers to transition for this population and the appropriate pathway from informal to formal work in the Latin American context. The objective of this article is to report the findings of an analysis of this transition in Colombia, where the institutional context explicitly promotes a formalisation pathway for waste picker organisations within the public waste management service in the waste picking activity. This analysis mixes quantitative and qualitative methods. The study draws on information from two main sources. First, primary data from a survey of individual waste pickers and waste picker organisations at the national level was considered. The second source was information analysis from workshops with waste picker leaders. The research's findings, conclusions, and recommendations compile barriers and opportunities for waste pickers, their organisations, and their formalisation. It is hoped that the findings will be used to guide similar studies in other developing countries with similar conditions for waste pickers. [ABSTRACT FROM AUTHOR]
