Urban households in developing countries are burning plastic waste in their homes to dispose of waste and as a cooking fuel to a greater extent than realized, according to a new study.Researchers surveyed urban households in 26 Global South countries in Africa, Asia and Latin America, revealing that this practice is widespread in some regions — particularly in parts of sub-Saharan Africa.Data suggest that urban households are burning plastics as fire starters, as a secondary fuel source and due to no alternatives to waste disposal.The burning of plastics is linked to serious health risks as well as environmental pollution. The authors urge further studies, along with targeted solutions to support marginalized communities with better fuel alternatives for cook fires and for plastic disposal.

Burning plastic waste for household fuel, or to manage household waste, may be far more prevalent in poor urban areas in developing countries than previously thought, raising serious environmental pollution and public health concerns for individuals, families and communities.

That’s according to a new global study that surveyed more than 1,000 “key informants,” including researchers, government workers and community leaders, from cities in 26 countries across the Global South. The researchers found that one-third of respondents are aware of households that are burning plastic, while 16% stated they’ve burned plastic in their own household.
