## Abstract

A solid composite material is suitable for construction and industrial uses. The solid composite material consists of at least an effective amount of assorted agricultural remnants with additives of calcium carbonate and antimony trioxide bound in an effective volume of cured resin. The cured material tolerates wet environments, is fire resistant, resistant to caustic substances and can be finished to provide a product having a desired appearance.

## Claims

### Claim 1

A solid composite material suitable for industrial and household uses, the material comprising an effective amount of assorted non-wood, fiberous agricultural remnants and effective amounts of additives comprising calcium carbonate and antimony trioxide, bound in an effective volume of cured resin, the assorted non-wood, fiberous agricultural remnants comprising:
cottonseed husk remnants;
pecan shell remnants;
rice seed hull remnants;
peanut shell;
soy bean remnants;
wheat remnants;
effective amounts of one or more additional components selected from the following: recycled plastics; fiber glass matting; E-glass and Q-cells; and
effective amounts of one or more additional additives selected from the following: talc, cobalt, titanium dioxide, graphite, hydrocal clay, and wollastonite, wherein the non-wood, fiberous agricultural remnants have an average fiber length sufficient to provide a three-dimensional amorphous weave.

### Claim 2 (depends on 1)

The composite material of claim 1, wherein the resin comprises a polyester resin.

### Claim 3 (depends on 1)

The composite material of claim 1, wherein the additives further comprise one or more selected thixotropes.

### Claim 4 (depends on 1)

The composite material of claim 1, wherein the additives further comprise one or more selected pigments.

### Claim 5

A solid composite material resistant to fire and caustic substances and suitable for industrial and household uses, the material comprising an effective amount of assorted non-wood, fiberous agricultural remnants and effective amounts of additives comprising calcium carbonate and antimony trioxide, bound in an effective volume of cured resin, the assorted non-wood, fiberous agricultural remnants comprising:
cottonseed husk remnants;
pecan shell remnants;
rice seed hull remnants;
soy bean remnants;
wheat remnants;
effective amounts of one or more additional components selected from the following: recycled plastics; fiber glass matting; E-glass and Q-cells; and
effective amounts of one or more additional additives selected from the following: talc, cobalt, titanium dioxide, graphite, hydrocal clay, and wollastonite,
whereby the solid composite material does not ignite upon exposure to temperatures up to 1400° Fahrenheit for five minutes and does not blister upon immersion in household bleach or a 40% v/v sulfuric acid solution for up to 8 hours, wherein the non-wood, fiberous agricultural remnants have an average fiber length sufficient to provide a three-dimensional amorphous weave.
