The use of plastic as a household fuel among the urban poor in the Global South
Increasing plastic waste pollution has led to a rising prevalence of the open burning of plastic waste, especially in locations lacking formal waste management systems. Urban slum communities face particularly acute challenges in accessing both organized waste-collection services and low-cost traditional energy sources, and clean cooking-fuel alternatives tend to be unaffordable for their low-income residents. Here we examine the potential risk these unseen communities face and describe the need for a new research agenda to better understand and quantify the scope of the problem.
