## Abstract

An improved material and process for decontaminating an organic chemical spill and animal waste is made by: partially composting plant material; adding spent mushroom compost; mixing some of the partially composted plant material with the dry plant material; inoculating the mixture with a small amount a petroleum hydrocarbon; adding iron sulfate, ammonium nitrate, or a mixture of iron sulfate and ammonium nitrate; adding water; and adding a clump preventing material. A nutrient may also be added to this mixture. The final product is mixed with the spilled organic chemical and allowed to incubate for a suitable time at ambient temperature. A similar material may be used as a pet litter.

## Claims

### Claim 1

A neutralizing material for absorbing and decontaminating an organic chemical spill comprising a mixture of:
a) partially composted plant material containing micro-organisms;
b) spent mushroom compost containing micro-organisms;
c) dry plant material containing micro-organisms;
d) a petroleum hydrocarbon;
e) iron sulfate, ammonium nitrate, or a mixture of iron sulfate and ammonium nitrate; and
f) a clump preventing material;
said neutralizing material capable of neutralizing an organic chemical spill when said neutralizing material is mixed with an organic chemical spill and allowed to incubate for a suitable time at ambient temperature.

### Claim 2 (depends on 1)

The material of claim 1 in which said plant material is selected from the group consisting of cotton, legumes, alfalfa, tomatoes, rice hulls, cotton gin trash, alfalfa hay, and their mixtures.

### Claim 3 (depends on 1)

The material of claim 1 in which said organic chemical is selected from the group consisting of diesel fuel, oil, gasoline, aviation fuel, paint solvent, trichloroethylene and their mixtures.

### Claim 4 (depends on 1)

The material of claim 1 in which said clump preventing material is selected from the group comprising mill cut saw dust, vermiculite, a diatomaceous earth, and mixtures thereof.

### Claim 5 (depends on 1)

The material of claim 1 further comprising a nutrient.

### Claim 6 (depends on 5)

The material of claim 5 in which said nutrient is selected from the group comprising raw sugar and sugar beet residue.

### Claim 7

A neutralizing material for absorbing and decontaminating animal waste comprising a mixture of:
a) partially composted plant material containing micro-organisms;
b) spent mushroom compost containing micro-organisms;
c) dry plant material containing micro-organisms;
d) a petroleum hydrocarbon;
e) iron sulfate, ammonium nitrate, or a mixture of iron sulfate and ammonium nitrate; and
f) a clump preventing material;
said neutralizing material capable of absorbing and decontaminating animal waste when said neutralizing material is mixed with animal waste and allowed to incubate for a suitable time at ambient temperature.

### Claim 8 (depends on 7)

The material of claim 7 in which said plant material is selected from the group consisting of cotton, legumes, alfalfa, tomatoes, rice hulls, cotton gin trash, alfalfa hay and their mixtures.

### Claim 9 (depends on 7)

The material of claim 7 in which said clump preventing material is selected from the group comprising mill cut saw dust, vermiculite, a diatomaceous earth, and mixtures thereof.

### Claim 10 (depends on 7)

The material of claim 7 further comprising a nutrient.

### Claim 11 (depends on 10)

The material of claim 10 in which said nutrient is selected from the group comprising raw sugar and sugar beet residue.
