DETAILED DESCRIPTION OF THE EMBODIMENTS
While the present invention is described herein with reference to illustrative embodiments for particular applications, it should be understood that the invention is not limited thereto. Those having ordinary skill in the art and access to the teachings provided herein will recognize additional modifications, applications, and embodiments within the scope thereof and additional fields in which the present invention would be of significant utility.
2 It is contemplated that the present invention provides a building component that can be comprised of comminuted paper, sawdust including hemp dust, and adhesive.
It is contemplated that the building component is made by forming a wet mixture comprising the comminuted paper, the sawdust including hemp dust, and the adhesive. This mixture can then be formed into the desired shape using a mold or, in other embodiments, extruded into the desired shape.
It is contemplated that the comminuted paper is preferably prepared by milling paper material in a mill such as but not limited to a hammer mill. It is contemplated that the paper material for comminution can be sourced from waste paper or waste cardboard.
It is contemplated that the saw dust can be ordinary sawdust from a sawmill including hemp stalks ground into saw dust.
It is contemplated that the adhesive can be any suitable adhesive. For indoor use where waterproofing is not necessary, a flour-based glue can be used. For use that requires a waterproof building component, such as a roof tile, a waterproof adhesive such as PVA glue is preferred.
In some embodiments, it is contemplated that the building component further comprises a biocide.
In some embodiments, it is contemplated that the building component further comprises a compression-resistant filler such as sand and/or a binder such as cement to improve the load-bearing properties of the building component. It will be appreciated that the inclusion of a compression-resistant filler and/or binder is preferred where the building component is expected to be load bearing.
It is contemplated that the building component is made by forming a wet mixture comprising the comminuted paper, the sawdust including hemp dust, and the adhesive. This mixture can then be formed into the desired shape using a mold or, in other embodiments, extruded into the desired shape.
It is contemplated that the comminuted paper is preferably prepared by milling paper material in a mill such as but not limited to a hammer mill. It is contemplated that the paper material for comminution can be sourced from waste paper or waste cardboard.
It is contemplated that the saw dust can be ordinary sawdust from a sawmill including hemp stalks ground into saw dust.
It is contemplated that the adhesive can be any suitable adhesive. For indoor use where waterproofing is not necessary, a flour-based glue can be used. For use that requires a waterproof building component, such as a roof tile, a waterproof adhesive such as PVA glue is preferred.
In some embodiments, it is contemplated that the building component further comprises a biocide.
In some embodiments, it is contemplated that the building component further comprises a compression-resistant filler such as sand and/or a binder such as cement to improve the load-bearing properties of the building component. It will be appreciated that the inclusion of a compression-resistant filler and/or binder is preferred where the building component is expected to be load bearing.
3 In some embodiments, the building component is shaped like a brick or a block.
In those embodiments, a conventional concrete block mold can be used to mold the building component.
In some embodiments, the building component is molded with through passages that extend transversely, vertically or laterally through the building component. It is contemplated that these channels reduce the amount of material required to manufacture them and further serve to reduce the weight of the product. In some embodiments the through passages are adapted to receive reinforcing rods. It will be appreciated that building components that are reinforced in this way are more suitable for use around door and window apertures.
In at least one embodiment, the building material is generally comprised of two parts comminuted paper to one part saw dust, which in some embodiments can include hemp dust.
The adhesive is generally in an amount roughly one tenth of the saw dust (including the hemp dust) and the comminuted paper. However, the ratio of comminuted paper to saw dust (including hemp dust) can be adjusted as high as 4:1 (paper:saw dust) and as low as 1:2 (paper:saw dust) according to the properties of the saw dust and the paper, and according to the desired properties of the building component.
In embodiments where the saw dust is the result of rip-cutting wood, less paper can be used because it will be appreciated that rip-cut saw dust is more fibrous and better able to interlock and reinforce itself between its pieces. In embodiments where the saw dust is the result of cross-cutting wood, it will be appreciated that more paper is desired to provide reinforcement.
Quantities of comminuted paper and saw dust should be measured by weight to ensure consistency because they are both comprised of essentially the same cellulosic material in different forms and having different densities.
In some embodiments, the comminuted paper and saw dust (including hemp dust) are mixed dry.

In some embodiments, the comminuted paper and saw dust (including hemp dust) are mixed dry.
4 In some embodiments, the comminuted paper and saw dust (including hemp dust) are mixed while the comminuted paper is wet, or while both the comminuted paper and the saw dust including hemp dust are wet.
Mixing is sufficient to produce a substantially homogeneous material. In a preferred embodiment, the mixture is sufficiently wet to be poured into molds as for producing roof tiles. In another preferred embodiment, the mixture is sufficiently wet to be shoveled by a hand shovel or trowel for use in individual molds.
In a preferred embodiment, a rectangular array of tile molds is used.
In embodiments wherein the building component further comprises compression-resistant filler such as sand and/or a binder such as cement, it is preferable to add binder in an amount of roughly half the amount of saw dust including hemp dust and comminuted paper;
and to add filler in an amount of roughly three quarters of the amount of cement.
It will be appreciated that having less filler than binder is contrary to normal building practice in which more sand than cement is the typically used.
It will be appreciated that the 2:3 ratio of sand to cement is not strictly required, as the amount of sand can be varied depending on the end user application. In many embodiments, a sand to cement ratio ranging from 2:3 to 2:1 will be satisfactory.
It is contemplated that more cement can also be used. In many embodiments, the ratio of sand to sawdust (including hemp dust) can be varied from substantially 1:1 to substantially 1:4.
Turning to FIG. 1, a diagram of a tile 1 is illustrated according to one embodiment. Tile 1 is molded from a mixture of: 6-8 gallons of wet comminuted paper, 3-4 gallons of saw dust including hemp dust, a half quart of waterproof PVA glue, and a half quart of water.
Tile 1 is molded in a cavity of multi-cavity mold 2 of FIG. 2.
The mixture is thoroughly mixed and pressed into a tile-shaped cavity of a mold such as the cavities of multi-cavity mold 2 of FIG. 2, and then they are left to cure.
Multi-cavity mold 2 is formed of metal and has cavities of suitable width and depth to form tile 1.
In this embodiment, mold 2 has 24 cavities.
The cured tile 1 can be used for roofing in the manner of shingles being nailed in place on battens.

Building block 11 is molded from a mixture of: 6-8 gallons of wet comminuted paper, 3-4 gallons of saw dust including hemp dust, a half quart of flour glue, a half quart of water, 114-2 gallons of sand, and 2%-3 gallons of cement. The amount of water may be adjusted to control the fluidity of the mixture such that it can be stamped into a concrete mold.
Building block 11 of FIG. 3 was molded in concrete block mold 14 of FIG. 4.
Molds such as concrete block mold 14 are known in the art.
The mixture for building block 11 was mixed well, stamped into the cavity of concrete block mold 14, and then left to cure until both the glue and cement have set.

Various modifications and changes consistent with the description as a whole and which are readily apparent to the person of skill in the art are intended to be included.
