A solid rocket propellant includes a hydroxy-terminated caprolactone ether binder and an oxidizer. The propellant may be disposed of by contacting it with an aqueous solution of 12 N NaOH or 6 N HCl at a temperature of about 140° F. for about 24 hours to decompose the binder. Solids remaining in the solution after the binder decomposes are removed.

1. A method of disposing of a solid rocket propellant, comprising the steps of:(a) contacting a propellant that comprises a hydroxy-terminated caprolactone ether (HTCE) binder and at least one or more solid compounds dispersed in the binder with a solution capable of hydrolyzing the binder to form hydrolyzed caprolactone and poly(tetramethylene ether), and (b) removing solids remaining in the solution after the binder hydrolyzes. 2. The method of claim 1, wherein the solids are recovered and recycled.3. The method of claim 1, wherein the hydrolyzed caprolactone and the poly(tetramethylene ether) are recovered and recycled.4. The method of claim 1, wherein at least one solid compound comprises an oxidizer that comprises ammonium nitrate, ammonium dinitramide, cyclotrimethylene trinitramide, or cyclotetramethylene tetranitramine and the propellant further comprises a plasticizer that comprises n-butyl nitratoethyl nitramine, trimethylol ethane trinitrate, or triethyleneglycol dinitrate, wherein the propellant comprises about 4 weight % to about 10 weight % HTCE binder, about 45 weight % to about 75 weight % oxidizer, and about 6 weight % to about 18 weight % plasticizer.5.
