If practices and public policies do not change, the mass of mismanaged plastic waste in the world will double to 121 million tonnes per year by 2050, according to a study published in Science. The article also assesses the potential impact of global measures, such as those envisaged by the forthcoming UN global treaty on plastic pollution, which begins its final negotiating session at the end of this month.
More than 52 million tonnes of plastic waste are emitted around the world every year, according to a study published in Nature that inventories plastic pollution in 50,702 cities. It concludes that littering is the largest source of plastic emissions in the global North, and uncollected waste is the largest source in the South.
In 2022, 62 million tonnes of e-waste were generated worldwide, a figure 82% higher than the 34 million tonnes recorded in 2010, according to a United Nations report. The 2022 figure represents an average of 7.8 kilograms per capita per year worldwide, compared to 19.6 kg in Spain. Only 22.3% of this amount of global e-waste was documented as properly collected and recycled, says the Global E-waste Monitor 2024.
A spill of plastic pellets from containers from the merchant ship Toconao has reached several areas of the Galician coastline. For its part, the Government of Asturias has upgraded the Accidental Marine Pollution Plan to phase 2 due to the detection of microplastics on the coast.
