We have worked with Rice Hull Ash for many years. It has great qualities for filtration, and as a topping for molten steel. It insulates for slow cooling without leaching carbon into the molten steel.
But another very timely application is Soil Remediation. We just delivered multiple truck loads of Rice Hull Ash to a site in the Northeast where it is being mixed with the soil to remove the volatiles from a site which has long been contaminated.
What a wonderful way to repair the earth.

The first step in product selection is determining the physical characteristics you want to impart to an end product. For example: increase or reduce weight; increase strength, flexibility or rigidity; add absorption characteristics; or introduce non-slip / anti-skid texture. The next step is to quantify the sought after attributes in the Filler or Extender, including particle shape or size; hardness; specific gravity; absorbency; reactive or inert; and temperature.
Some examples of Filler and Extender applications include Extruded Lumber: Rice Hulls, Wood Flour; Plywood Adhesive Extender and Flex Strength additive: Walnut Shell Flour, Wood Flour; Non-Skid / Textured Coatings: Plasti-Grit, Walnut Shell Grit, Clear Thermoset Grit; Composite Flex Strengtheners: Kenaf, Cotton, Rayon Fibers; Ceramic Aeration additive (Burn-out): Walnut Shell Grit.
