Plastic consumption is projected to double in the world’s 20 biggest economies by 2050, new research has found. The Group of 20 nations account for 80 per cent of global plastic consumtion and waste and are currently on track to produce an estimated 53 million metric tons of plastic waste per year by 2030, up from 40 million metric tons in 2015. By 2050, this figure could double to 110 million metric tons per year if no action is taken, said the study by research group Back to Blue. It pointed out that existing national bans and curbs have failed to address the pollution crisis and called for a sweeping set of new global policies, including worldwide bans on some single-use plastic products to effectively combat growing plastic pollution. “Proper plastic management is the biggest challenge facing us today,” said Aafrin Kidwai, the editor-in-chief of Solid Waste India, a portal that carries news about the waste sector. “With mounting evidence that the world is generating more single-use plastics than ever before, the Back to Blue report plays a crucial role in identifying countries that are likely to become major sources of such waste.” Increasing demand for single-use plastics and limited recycling capacities in many countries are major drivers of this trend, the study said, and called for urgent measures to reduce plastic consumption, improve recycling rates and promote alternative materials.
