During alkaline hydrolysis, a human body is sealed in a long, stainless-steel chamber, while a heated solution of 95 percent water and 5 percent sodium hydroxide passes over and around it. In low-temperature alkaline hydrolysis, the solution reaches a temperature just below boiling, the process is performed at atmospheric pressure, and the body is reduced over the course of 14 to 16 hours; in a higher-temperature version of the process where the mixture tops 300 degrees Fahrenheit and creates more pressure, the body is reduced in four to six hours. The process dissolves the bonds in the body’s tissues and eventually yields a sterile, liquid combination of amino acids, peptides, salts, sugars and soaps, which is disposed of down the drain at the alkaline hydrolysis facility. The body’s bones are then ground to a fine powder and returned to the deceased person’s survivors, just as the bones that remain after flame cremation are returned to families as ash.
