ABSTRACT
Reports that the stalks and leaves left over after hops are harvested to make beer could help decontaminate watercourses and industrial waste water polluted with heavy metals, as illustrated by Kirk Tiemann and colleagues at the University of Texas at El Paso. Effectiveness of hops at stripping metal ions out of water; How acid can be used to separate the metal from the biomass so that both can be reused.
