Waste pickers have drawn the increasing attention of scholars in a range of academic disciplinary fields. These have included environmental and sanitation engineering, political economics, urban anthropology, urban geography, and other scholarly works (Dias 2016). Waste pickers collect materials thrown away by others, including metal, food, clothes, paper, and plastics. They collect these materials from different sources such as streets, on landfills and open dumpsites areas (WIEGO 2020a).
