Promession is an idea of how to dispose human remains by way of freeze drying. The concept of promession was developed by Sweden biologist Susanne Wiigh-Mäsak, who derived the name from the Italian language word for "promise" ( promessa).
Process
The idea of promession involves five steps:
-
Coffin separation: the body is placed into the chamber
-
Cryogenic freezing: liquid nitrogen at −196 °C crystallizes the body
-
Vibration: the body is disintegrated into particles within minutes
-
Freeze drying: particles are freeze dried in a drying chamber, leaving approximately 30% of the original weight
-
Metal separation: any metals (e.g., tooth amalgam, Hip replacement, etc.) are removed, either by magnetism or by Sieve. The dry powder is placed in a Biodegradation casket which is interred in the top Soil horizon, where aerobic bacteria decompose the remains into humus in as little as 6–12 months.
Criticism
Promession as a functional method is questioned. No facility for promession has been built or put into service. Critics argue that there is a physical
impossibility to atomize a freeze dried human body in this way.
Current status
Promessa Organic AB was liquidated in 2015 without being able to produce a functioning module or facility.
