Gold Recycling Goes Green with Biodiesel Innovation

Chalmers University of Technology researchers have developed an environmentally friendly method for recycling and purifying metals. Using gold earrings from a pawnshop in Gothenburg and biodiesel from the nearest filling station, the discovery could change an industry that is currently dependent on large amounts of fossil oil. The scientific article ‘Sustainable solvent extraction of gold and other metals with biomass chemicals’ has been published in the journal RSC Sustainability (Available Open Access). The authors of the study are…
