Aquamation, also known as alkaline hydrolysis or water cremation, is an eco-friendly alternative to traditional flame cremation. It uses a combination of water, alkaline chemicals, and heat to break down the body in a process that mirrors natural decomposition. This method avoids the use of fire and greatly reduces environmental impact, making it an increasingly popular option.
How Long Does Aquamation Take?
The aquamation process typically takes between 6 to 16 hours, depending on the temperature and equipment used. Higher-temperature systems can complete the process faster, while lower-temperature systems may take longer. Despite the extended timeframe, aquamation is considered a gentle and environmentally conscious method of body disposition.
How Does This Compare to Traditional Cremation?
By comparison, traditional flame-based cremation generally takes 2 to 3 hours to complete. The body is exposed to intense heat, reaching temperatures of 1,400 to 2,000°F (760 to 1,093°C), which rapidly reduces the body to bone fragments and ash. After cremation, the remains are processed into fine ashes and returned to the family, similar to the aquamation process. However, flame cremation has a larger environmental footprint due to energy consumption and emissions.
What Happens During Aquamation?
- Preparation: The body is placed in a stainless steel chamber filled with water and an alkaline solution, usually potassium hydroxide or sodium hydroxide.
- Decomposition: The chamber is heated to between 200–300°F (93–150°C). Over the course of several hours, the water and alkaline chemicals break down the body’s tissues, simulating natural decomposition in a much shorter time.
- Completion: Once the soft tissues have dissolved, only the bones remain. These are removed, dried, and processed into a fine, white ash.
- Returning Ashes: The ashes are returned to the family, much like in flame cremation.
Why Consider Aquamation?
Aquamation offers a greener, more sustainable alternative to flame cremation. It uses up to 90% less energy and produces fewer emissions. The process results in a non-toxic liquid that can be safely returned to the water system, reducing the environmental impact. While it takes longer than traditional cremation, aquamation is gaining popularity for its environmental benefits and gentler handling of remains.
For those seeking an eco-conscious approach to final arrangements, aquamation provides a meaningful option with a lower environmental footprint.
