10 Sep 2024 --- Researchers at the University of Leeds, UK, are being criticized by environmentalists over a recent study into global macroplastic pollution, which highlighted disproportionate levels of waste incineration and emissions in countries in the Global South. The study authors say their findings could inform the UN Global Plastic Treaty, but critics say the research ignores a fundamental “waste colonialism” narrative. Macroplastics are plastic items with a diameter larger than 5 mm, distinguished from microplastics, which are smaller than 5 mm.
