Abstract
Provided are a structure and a method of forming a structure that includes a core made, at least in part, of a rice hull composition. The rice hull composition including a combination of separate, unground rice hulls; ground rice hulls; and a rice hull powder, that each have a different particle size. A polymeric binder, such as a recycled plastic polymeric binder binds the separated unground rice hulls, the ground rice hulls and the rice hull powder together.
Claims14
A method of forming a structure comprising rice hulls, the method comprising:
- forming a rice hull composition comprising:
- combining separated unground rice hulls, ground rice hulls and a rice hull powder, wherein the separated unground rice hulls, the ground rice hulls and the rice hull powder each comprises a different particle size, with a polymeric binder selected from the group consisting of polyethylene, high density polyethylene, low density polyethylene, polypropylene, polyethylene terephthalate, nylon, Teflon, polystyrene, acrylonitrile butadiene styrene, fiber-reinforced plastic, and combinations thereof;
- introducing the rice hull composition to an extruder to form a rice hull extrudate, wherein the extruder is pre-heated to a temperature of from about 270° F. to about 450° F.;
- and
- cooling the rice hull extrudate to obtain the structure.
