[Recyclable material waste pickers: an analysis of working conditions and operational infrastructure in the south, southeast and northeast of Brazil].

This work is a survey of information gathered from waste pickers in the south, southeast and northeast of Brazil in order to provide input for the development of a waste collection vehicle and a support system to define waste collection routes. Thus, the research sought to establish the profile of waste pickers, diagnose their working conditions and identify the physical and operational structure of the organizations to which they are linked. To achieve these objectives it was necessary to apply questionnaires to waste pickers from organizations who performed the collection of recyclable materials using human- and animal-drawn vehicles and the waste picking organizations themselves.
