Water cremation, or aquamation, uses a water-based process to return the body to its basic elements. Unlike traditional cremation, which uses high heat and flame, aquamation relies on a gentle combination of water, heat, and alkaline chemicals. The process mimics natural decomposition but accelerates it, typically taking 6 to 8 hours. The result is a sterile liquid and bone fragments, which are processed into a fine powder and returned to the family, much like ashes from flame cremation.
During aquamation, the body is placed in a stainless steel vessel filled with water and a small amount of potassium hydroxide or sodium hydroxide. The solution is heated to around 300 degrees Fahrenheit under pressure to prevent boiling. Over several hours, the body breaks down, leaving only bone fragments and a harmless liquid. The bones are then rinsed, dried, and processed into a powder for the family.
| Aspect | Water Cremation | Traditional Cremation |
|---|---|---|
| Process | Alkaline hydrolysis with water and alkali | High heat and flame |
| Environmental Impact | Low emissions, uses less energy | Releases carbon dioxide and mercury |
| Remains Returned | Powdered bone (similar to ashes) | Ashes |
One of the main reasons families choose water cremation is its reduced environmental footprint. The process uses about 90 percent less energy than flame cremation and does not release harmful greenhouse gases or mercury into the atmosphere. The sterile liquid byproduct is safe for disposal in the municipal water system. This makes aquamation a preferred choice for those seeking a green funeral option.
Water cremation is legal in a growing number of states and countries, but availability can vary. It is important to check with local funeral providers to see if aquamation is offered in your area. Costs are generally comparable to or slightly higher than traditional cremation, but many families find the environmental benefits outweigh the difference.
