Water cremation is a process that uses water, heat, and alkaline chemicals to accelerate the natural decomposition of the body. Unlike flame cremation, which uses high temperatures to reduce the body to bone fragments, water cremation gently dissolves soft tissue, leaving only the bone remains. The process is sometimes called aquamation or resomation, and it is recognized for its minimal environmental impact.
The procedure takes place in a specially designed stainless steel vessel. The body is placed inside, and a solution of water and potassium hydroxide is added. The vessel is heated to around 300 degrees Fahrenheit and pressurized to prevent boiling. Over several hours, the solution breaks down organic material, leaving behind only the bone fragments and a sterile liquid. The bones are then processed into a fine powder, similar to traditional cremated remains, and returned to the family.
| Method | Environmental Impact | Remains Returned |
|---|---|---|
| Water Cremation | Low - minimal emissions, low energy use | Powdered bone (ashes) |
| Flame Cremation | Moderate - CO2 and mercury emissions | Powdered bone (ashes) |
| Traditional Burial | High - land use, embalming chemicals | Body (in casket) |
Water cremation is legal in a growing number of states and provinces. However, availability varies by region, and not all funeral homes offer this service yet. If you are interested, check with local providers or consult resources like The Funeral Program Site for up-to-date information.
