Chromium dioxide may be another feasible option, as it is found in cassette tapes and can be recycled with them. Inhalation of dust causes irritation of nose and throat. They can, however, be converted to aluminium sulfate, which is safe to dispose of in soil, though it will cause a decrease in pH (it is used as a fertilizer for this purpose), and in diluted form can be poured down the drain, as at low concentrations it's used in the treatment of water. Examples of these are sulfide, sulfate, chloride, chlorate, nitrate, nitrite, thiocyanate.[1]. For quicker results, alkali bases can be neutralized with any acid, though for practical and economical purposes, acetic acid or citric acid are sufficient.

Always check the local laws before choosing the disposal method. Although small amounts can be diluted with large amounts of water and poured down the drain, 1,4-dioxane does not undergo significant biodegradation and most will end up in the environment. The resulting cyanates will slowly hydrolyze in basic environment to ammonium carbonates, while excess bleach/oxidizer will further convert them to nitrogen and carbon dioxide. Office of Response and Restoration, cooking salt) activates the etch by diminishing the bond with water. The resulting solutions contain moderate concentrations of hydrogen ions and have pH's of less than 7.0.
