As world leaders arrive at United Nations climate talks in the Turkish resort town of Antalya, calling for urgent climate action, co-host Turkey also wants to halve the amount of global waste in the next decade. While the transition away from fossil fuels and the push for electrification through renewables is the cornerstone of this year’s conference, known as COP31, experts say reusing materials and more efficient manufacturing can also play a big role in cutting planet-heating emissions. Analysts say that reusing materials instead of investing in more mining in the creation of new technology, like solar panels and batteries, could be a major cost saver for nations.
