A Cornell University-led research team has developed a novel method to recover gold from discarded electronics and utilize it as a catalyst to convert CO2 into valuable organic compounds. This dual approach addresses the growing concerns of e-waste recycling and CO2 reduction.
The team’s innovation recovers gold from discarded electronics and uses it as a catalyst to transform CO2 into useful organic materials.A novel method developed by a Cornell-led research team offers a dual solution to two pressing environmental problems: e-waste recycling and carbon dioxide reduction .
With approximately 50 million tons of electronic waste generated annually—and only 20% of it recycled—this approach could help alleviate the environmental burden, according to Amin Zadehnazari, lead researcher and postdoctoral scientist in the lab of Professor Alireza Abbaspourrad at Cornell University.Electronics waste is a surprisingly rich source of gold, containing at least 10 times more of the metal per ton than natural gold ore.
“We can use the gold-loaded COFs to convert CO2 into useful chemicals,” Zadehnazari said. “By transforming CO2 into value-added materials, we not only reduce waste disposal demands, we also provide both environmental and practical benefits. It’s kind of a win-win for the environment.”

Gold Entrapment: How Earth's Vulcanoes Drive Gold to the SurfaceScientists have uncovered the mystery behind gold's journey from Earth's mantle to the surface. A specific type of sulfur, under extreme pressure and temperature, acts as a catalyst, enabling gold to bond and be transported by volcanic activity. Subduction zones, where tectonic plates collide, are key areas for this process, explaining the concentration of gold deposits near volcanoes.
