Researchers created eco-friendly adsorbents from reishi (Ganoderma lucidum) and its calcined form to remove the hormone progesterone—an endocrine-disrupting chemical—from water. Under optimal conditions, the calcined reishi removed up to 118.1 mg/g, outperforming many conventional methods. Even better, the used adsorbents doubled as agricultural enhancers, improving seed germination by 95%, shoot-to-root ratio, and soil fertility, all while scoring a 94/100 on the eco-sustainability scale.
