rice hulls

The hard, protective shells formed over rice grains resist moisture penetration and are excellent insulation materials, with a thermal resistance of about R 3.0 per inch. They are fire resistant and resistant to rot, molds, mildew, insects, rodents, and fungus. Rice hull interlocking panels exhibit excellent load bearing capability, sound absorption and fire resistance. See also: Biomaterials

Traditionally, rice husk/rice hulls are being used as a component in cattle and poultry feeds in limited quantity due to low nutrients digestibility, high silica/ash content and coarse feeding characteristics (Naseer et al., 2017) Rice hulls contains lowest total digestible nutrients, among all cereal by-products (Sataar et al.,2015).
The company uses the following sustainable materials: * Kenaf, a tropical plant in the cotton family, is used in the door bolsters of Ford Escape * Rice hulls are used to reinforce plastic in the Ford F-150 electrical harness * Soy-based foams are used as seat cushions, seatbacks and head restraints * Wheat straw is used in Ford Flex to reinforce storage bins * Cellulose tree fibers are used to replace glass-filled plastic; this industry-first material weighs 10 percent less, is produced 30 percent faster, and reduces carbon emissions.
