Empty fruit bunches (EFB) from oil palm processing are being explored as a source of nanolignin for environmentally friendly heavy-metal adsorption. Research shows the biomaterial can remove lead ions (Pb²⁺) from water, opening opportunities for higher-value applications of palm oil waste. Photo: Sawit Fest 2021/ Nealsen Nathaniel
