AgCenter scientists have discovered a novel use for rice hulls as a biofiltration medium. The high amount of surface area, low carbon content and unique shape promote the growth of bacteria that degrade pollutants. Because rice hulls are waste materials, they are readily available and affordable for use. In addition, their high silica content prevents them from degrading quickly.
