Abstract
Waste pickers make significant contributions to public health, sanitation, and the environment by promoting resource circulation and reducing the amount of landfill. However, they are often not legally recognized as workers and suffer from poor working conditions and lack of social protection. This brief highlights the role of waste pickers' cooperatives and other social and solidarity economy organizations (SSEOs) in integrating and formalizing the work of waste pickers in the recycling value chain and improving their working conditions.
