Abstract
A method of manufacturing an erosion, sediment and pollution control product comprises heat treating a rice hull filler material for sterilizing the rice hull filler material and increasing the pollutant affinity of the rice hull filler material; filling a tubular containment member with the rice hull filler material in a manner allowing fluid to flow through the containment member and the rice hull filler material. The containment member is a geotextile which may include cellulose based threads treated to be hydrophobic.

A method of manufacturing an erosion, sediment and pollution control product comprising:
- Sterilizing at least a portion of an erosion, sediment and pollution control product filler material, wherein the filler material includes rice hulls;
- Homogenizing the filler material;
- Providing a tubular mesh member geotextile which exhibits a fabric flow test of at least 100 Gallons per minute based upon permittivity test results in a ASTM 4491 type C testing protocol;
- Filling the tubular mesh member with the homogenized filler material containing the rice hulls and wherein the filled tubular mesh member and filler material is configured to allow fluid to flow through the mesh member and the filler material.
