## Abstract

A process and composition for the beneficial utilization of waste materials which contain energetic materials are disclosed. Predetermined quantities of the waste material containing energetic materials are placed in admixture with commercial blasting agents causing the energetic materials to participate in the detonation process thereby utilizing energetic materials which would otherwise enter the waste stream. The waste material, in particulate form, that contains the energetic material is introduced into the blasting agent when the latter is in a relatively fluid state. The modified blasting agent is suitable for use in the normal manner such as in bulk or packaged form.

## Claims

### Claim 1

A modified blasting agent comprised of a high velocity detonation wave blasting agent and waste material which contains an energetic material, the waste material being in particulate form in admixture with the high velocity detonation wave blasting agent wherein the quantity and particulate size of said waste material is such that the ingredients in the waste material participate in the high velocity detonation process, wherein the energetic material is a composite solid propellant designated class 1.3, and wherein the blasting agent in admixture with the waste material is a slurry blasting agent and wherein the upper limit of size of the waste material is the point where a further increase in size will cause the detonation process not to occur and the upper limit in quantity of the waste material is the point where a further increase in quantity of waste material will cause the detonation not to occur.

### Claim 2 (depends on 1)

A modified blasting agent as in claim 1 wherein the slurry blasting agent is a watergel.

### Claim 3 (depends on 1)

A modified blasting agent as in claim 1 wherein the slurry includes an emulsion.

### Claim 4 (depends on 1)

A modified blasting agent as in claim 1 wherein the waste material contains a stoichiometric excess of ingredients which are predominantly fuel in character.

### Claim 5 (depends on 4)

A modified blasting agent as in claim 4 wherein the waste material further contains items contaminated with composite propellant.

### Claim 6 (depends on 4)

A modified blasting agent as in claim 4 wherein the waste material further contains items contaminated with 1.3 or 1.1 composite propellant.

### Claim 7 (depends on 4)

The modified blasting agent of claim 4 further comprising a stoichiometric amount of an oxidizer.

### Claim 8 (depends on 1)

The modified blasting agent of claim 1 wherein the waste material contains a stoichiometric excess of ingredients which are primarily oxidizer in character.

### Claim 9 (depends on 8)

The modified blasting agent of claim 8 further comprising a stoichiometric amount of a fuel.
