The Cremation Association of North America (CANNA), an international non-profit organization, defines aquamation, or alkaline hydrolysis, as flammable cremation. In this procedure, the body is placed in an alkaline hydrolysis machine, which consists of a hermetic chamber filled with water and a solution based on alkaline chemicals. Afterwards, the chamber is heated and at the end of the process only bones remain as per the organization.
Once the bones are dry, they can be pulverized. The CANA website states, “This process results in approximately 32% more funeral rites than flame-based cremation and may require a larger urn.”
