Water cremation, or alkaline hydrolysis, is a process that uses water, heat, and a gentle alkaline solution to accelerate natural decomposition. Unlike flame cremation, which relies on high temperatures and combustion, water cremation mimics the natural breakdown that occurs in the earth, but does so in a matter of hours instead of years. The process is sometimes called aquamation, bio-cremation, or resomation. It is recognized for its low environmental impact and is increasingly available at funeral homes across the United States and beyond.
The water cremation process involves placing the body in a specialized stainless steel vessel. The vessel is filled with a solution of 95 percent water and 5 percent alkali, then gently heated and circulated. Over several hours, the solution breaks down organic material, leaving behind only bone fragments and a sterile liquid. The bone fragments are then processed into a fine powder, similar to traditional cremated remains, and returned to the family in an urn. The liquid byproduct is completely sterile and can be safely returned to the environment.
