## Abstract

Animal bedding having one or more solvents and a lignocellulosic fiber, wherein the lignocellulosic fiber has been processed by ruminant digestion and anaerobic digestion. A method for preparing pelletized animal bedding is also disclosed including the steps of providing excrement from a cow which has undergone ruminant digestion, introducing the cow excrement into an anaerobic digester, modifying the cow excrement to a first wet product, drying the first wet product to generate a first dry product, and densifying the first dry product to, in turn, generate pelletized animal bedding.

## Claims

### Claim 1

Animal bedding, comprising:
at least one solvent; and
a lignocellulosic fiber, wherein the lignocellulosic fiber has been processed by ruminant digestion and anaerobic digestion.

### Claim 2 (depends on 1)

The animal bedding according to claim 1, wherein the at least one solvent comprises water.

### Claim 3 (depends on 1)

The animal bedding according to claim 1, wherein the at least one solvent is present in a concentration of less than approximately 70% by weight.

### Claim 4 (depends on 1)

The animal bedding according to claim 1, wherein the at least one solvent is present in a concentration of less than approximately 50% weight.

### Claim 5 (depends on 1)

The animal bedding according to claim 1, wherein the lignocellulosic fiber compromises processed lignin, hemicellulose, and cellulose.

### Claim 6 (depends on 1)

The animal bedding according to claim 1, wherein the density fiber of the animal bedding ranges from approximately 0.950 grams per cubic centimeter to approximately 1.40 grams per cubic centimeter.

### Claim 7 (depends on 1)

The animal bedding according to claim 1, wherein the pH of the animal bedding is alkaline.

### Claim 8 (depends on 1)

The animal bedding according to claim 1, wherein the pH of the animal bedding ranges from greater than approximately 8 to less than approximately 10.5.

### Claim 9 (depends on 1)

The animal bedding according to claim 1, wherein average particle size of the lignocellulosic fiber is less than approximately 10 microns.

### Claim 10 (depends on 1)

The animal bedding according to claim 1, wherein animal bedding is pelletized.

### Claim 11 (depends on 10)

The animal bedding according to claim 10, wherein the specific density of the animal bedding pellets ranges from approximately 0.400 grams per cubic centimeter to approximately 0.850 grams per cubic centimeter.

### Claim 12 (depends on 10)

The animal bedding according to claim 10, wherein the at least one solvent is present in a concentration of less than approximately 25% by weight.

### Claim 13 (depends on 10)

The animal bedding according to claim 10, further comprising an odor suppressant.

### Claim 14 (depends on 13)

The animal bedding according to claim 13, wherein the odor suppressant comprises an organic ester.

### Claim 15 (depends on 1)

The animal bedding according to claim 1, further comprising 3-amino-7-dimethylamino-2-methylphenazine hydrochloride.

### Claim 16 (depends on 1)

The animal bedding according to claim 1, further comprising 3,3-bis(4-hydroxy-2-methyl-5-propan-2-ylphenyl)-2-benzofuran-1-one.

### Claim 17 (depends on 1)

The animal bedding according to claim 1, wherein the lignocellulosic fiber is present in a concentration of greater than approximately 40% by weight.

### Claim 18 (depends on 1)

The animal bedding according to claim 1, wherein the lignocellulosic fiber is present in a concentration of greater than approximately 50% by weight.

### Claim 19

Pelletized animal bedding derived from cow excrement, comprising:
at least one pellet comprising a solvent and a lignocellulosic fiber, wherein the lignocellulosic fiber has been processed by ruminant cow digestion and anaerobic digestion.

### Claim 20

A method for preparing pelletized animal bedding, comprising the steps of:
providing excrement from a cow which has undergone ruminant digestion;
introducing the cow excrement into an anaerobic digester;
modifying the cow excrement to a first wet product;
drying the first wet product to generate a first dry product; and
densifying the first dry product to, in turn, generate pelletized animal bedding.

### Claim 21 (depends on 20)

The method according to claim 20, further comprising the step of bleaching the first dry product before the step of densifying the first dry product.
