well i don't know about "should have known," but still
What is aquamation?Aquamation, which uses water, is touted as a greener alternative to cremation, which uses fire. Practitioners say it cuts the amount of environmentally harmful carbon dioxide produced by up to 90%.
The technical name for the process is alkaline hydrolysis - and it involves weighing the body, then heating it to 150C (300F) in a mixture of potassium hydroxide and water for up to 90 minutes.
This dissolves the body tissue, leaving only the bones - which are then rinsed at 120C, dried, and pulverised into a coarse powder using a machine called a cremulator.
Once all these steps are complete, the remains can be buried or scattered in accordance with the deceased's wishes - just as would happen in an ordinary cremation.
