However, the disposable nature of these products has linked synthetic plastic microbeads to pollution in marine environments. In this study, we present a sustainable alternative by using brewer's spent grain as our starting material. Through solubilization and regeneration, we transform this brewery residue into spherical lignocellulosic microbeads. Beyond mitigating the environmental impact associated with exfoliating microbeads in personal care items, this method introduces an innovative valorization strategy for brewer's spent grain.
