Composite product formed of coffee grounds

1 . A method of manufacturing a composite product with spent coffee grounds, comprising:

acquiring spent coffee grounds;

pre-drying the spent coffee grounds;

drying the spent grounds that have been pre-dried, to form base material;

organizing the base material by size;

forming base products from the base material, including a resin product and a hardener product;

forming a mixed product from the base products; and

forming a final product from the mixed product, wherein the final product is the composite product,

wherein organizing the base material by size includes:

screening or sifting the base material into fine and course granules;

vacuum sealing the spent grounds based on size; and

storing the spent grounds.

2 . The method of claim 1 , wherein acquiring spent coffee grounds includes:

storing the spent grounds in a recycling receptacle; and

removing inorganic material.

3 . The method of claim 1 , wherein pre-drying the spent coffee grounds includes:

draining the spent grounds of water;

air drying the spent grounds; and

transferring the spent grounds into a drying vat.

4 . The method of claim 1 , wherein drying the spent coffee grounds includes:

monitoring a moisture content of the spent grounds until a target moisture content is obtained;

transferring the spent grounds into a powered dryer;

transferring the spent grounds onto a baking pan;

transferring the pan into a humidity-controlled environment; and

periodically agitating or mixing the spent grounds.

5 . The method of claim 4 , wherein transferring the pan into the humidity controlled environment includes transferring the pan into an oven.

6 . The method of claim 4 , wherein drying the spent coffee grounds further includes utilizing open air convection, conduction, radiation.

7 . The method of claim 1 , wherein organizing the base material by size further includes milling a quantity of the base material into a flour.

8 . The method of claim 1 , wherein forming the resin product includes:

mixing resin with one or more of flour, fine, and course granules of the base material to define a resin product; and

degassing the resin product.

9 . The method of claim 8 , wherein degassing the resin product includes one or both of:

manual degassing; and

powered degassing.

10 . The method of claim 1 , wherein forming the hardener product includes:

mixing a hardener with one or more of flour, fine, and course granules of the base material to define the hardener product; and

degassing the hardener product.

11 . The method of claim 1 , wherein forming the mixed product from the base products includes:

heating the resin product and the hardener product to a first working temperature;

mixing the resin and hardener products with each other; and

degassing the mixed product.

12 . The method of claim 11 , wherein forming the mixed product from the base products further includes introducing one or more additives into the mixed product.

13 . The method of claim 11 , wherein degassing the mixed product includes one or both of:

manual degassing; and

powered degassing.

14 . The method of claim 1 , wherein forming the final product from the mixed product includes one or more of:

pouring the mixed product into a mold;

pouring the mixed product into an injection molding device; and

forming a filament for additive manufacturing.

15 . The method of claim 14 , wherein forming the final product from the mixed product includes:

pouring the mixed product into the mold;

introducing a structural insert in the mixed product that is in the mold; and

machining a product of the mold into the final product.

16 . The method of claim 14 , wherein forming the final product from the mixed product includes:

pouring the mixed product into the injection molding device; and

injection molding the final product.

17 . The method of claim 14 , wherein forming the final product from the mixed product includes:

forming the filament for additive manufacturing; and

additively manufacturing the final product.

18 . The method of claim 14 , further comprising coating the final product in a resin-based colorant to change its appearance.

19 . A composite product formed by a method according to claim 1 .
