Olive Waste Biochar Boosts CO2 Conversion to Methane

Chemical engineers at the University of Castilla-La Mancha in Spain found that olive stones, when treated with zinc chloride at high temperatures, yield activated biochars with exceptionally high surface areas that can host nickel nanoparticles for carbon dioxide methanation


Every year, the olive oil industry leaves behind mountains of stones and pomace—hard, carbon-rich residues that are usually burned as…
