research team led by Cornell University has unveiled an innovative method to extract gold from electronic waste and repurpose it as a catalyst for converting carbon dioxide (<em>CO<\/em><sub>2<\/sub>) into organic materials. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This pioneering technique, detailed in a paper <a href=\"https:\/\/www.nature.com\/articles\/s41467-024-55156-3\" target=\"_blank\" rel=\"noopener\" title=\"\">published<\/a> in the journal Nature Communications, offers a promising solution to the global e-waste problem, which currently sees only 20% of the approximately 50 million tons discarded each year being recycled.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Amin Zadehnazari, a postdoctoral researcher in the lab of Alireza Abbaspourrad, the Yongkeun Joh Associate Professor of Food Chemistry and Ingredient Technology in Cornell&#8217;s College of Agriculture and Life Sciences, has synthesized vinyl-linked covalent organic frameworks (VCOFs) that effectively remove gold ions and nanoparticles from circuit boards in discarded electronics. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Remarkably, one of these VCOFs was able to selectively capture 99.9% of the gold while leaving behind other metals, such as nickel and copper.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">&#8220;We can then use the gold-loaded COFs to convert <em>CO<\/em><sub>2<\/sub> into useful chemicals,&#8221; Zadehnazari, the lead author, said in a <a href=\"https:\/\/news.cornell.edu\/stories\/2025\/01\/e-waste-gold-pathway-co2-sustainability\" target=\"_blank\" rel=\"noopener\" title=\"\">news release<\/a>. &#8220;By transforming <em>CO<\/em><sub>2<\/sub> into value-added materials, we not only reduce waste disposal demands, we also provide both environmental and practical benefits. It&#8217;s kind of a win-win for the environment.&#8221;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">E-waste is often considered a literal gold mine, as a ton of e-waste contains at least 10 times more gold than a ton of traditional gold ore. With projections indicating an increase to 80 million metric tons of e-waste by 2030, the need for effective recovery methods is more urgent than ever. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Unlike traditional gold recovery processes that involve hazardous chemicals such as cyanide, Zadehnazari&#8217;s approach leverages chemical adsorption to capture gold, thereby mitigating environmental risks.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cKnowing how much gold and other precious metals go into these type of electronics devices, being able to recover them in a way where you can selectively capture the metal you want &#8212; in this case, gold &#8212; is very important,\u201d added Abbaspourrad, the corresponding author.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This breakthrough not only paves the way for more sustainable electronic waste management but also highlights the potential of transforming <em>CO<\/em><sub>2<\/sub>, a major greenhouse gas, into valuable organic materials. This dual impact exemplifies innovative thinking in addressing some of the most pressing environmental challenges of our time.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>In a groundbreaking advancement for environmental sustainability, a research team led by Cornell University has unveiled an innovative method to extract gold from electronic waste and repurpose it as a catalyst for converting carbon dioxide (CO2) into organic materials.
