Disposing old or unused Estes rocket engines is fairly straightforward. Section 13 of this Safety Data Sheet from Apogee states: “To dispose of a small quantity of product, soak in water for at least 24 hours, then dispose of remnants in an ordinary manner. For large quantities, contact manufacturer or incinerate.

A traditional sugar propellant formulation is typically prepared in a 65:35 (13:7) oxidizer to fuel ratio. There are many different methods for preparation of a sugar-based rocket propellant. In the United States, rocket candy motors are legal to make, but illegal to transport without a low explosives users permit.
