The world is facing a global plastics crisis with more than 50% of plastics produced only being used once and then discarded. If nothing is done to put an end to plastic pollution, it is projected that by 2050, there will be more plastic (by weight) than fish in the ocean, affecting natural ecosystems, biodiversity and human health. While solutions often target governments and corporations, a crucial group is frequently ignored: informal waste pickers. Despite the limitations of recycling alone, waste pickers significantly impact the plastic recycling chain. This review addresses the gap in our understanding of their role. It argues that waste pickers are an essential component of the larger portfolio of solutions for the plastic crisis but face significant challenges.
