rice hulls
Milled cereal casings
Rice hulls are the hard outer coverings of rice grains, removed during milling.
These lightweight, fibrous husks have numerous uses: as animal bedding, garden mulch, brewing filtration material, and fuel.
In construction, rice hulls serve as insulation or filler in composite materials.
Also called rice husks.
