Promession is an idea of how to dispose human remains by way of freeze drying. The concept of promession was developed by Swedish biologist Susanne Wiigh-Mäsak, who derived the name from the Italian word for "promise" (promessa).[1] She founded Promessa Organic AB in 1997 to commercially pursue her idea.[2] The company went bankrupt in 2015 without being able to produce a functioning facility.[3] The idea of promession is questioned and not a functional method according to critics.[4]
The idea of promession involves five steps:
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[5] impossibility to atomize a freeze dried human body in this way.[4][6]
Promessa Organic AB was liquidated in 2015 without being able to produce a functioning module or facility.[3]
