Promession is an ecologically-conscious method for disposing of human remains by freeze drying. It was invented and patented in 1999 by the Swedish biologist Susanne Wiigh-Mäsak.
The method is based on three steps:
1. Reducing the body of the deceased to a fine powder, thereby allowing subsequent decomposition to be aerobic. This is achieved by submerging the body in liquid nitrogen, making the remains so brittle that they shatter into a powder as the result of slight vibrations. The powder is then dried, reducing the deceased remains to around 30% of their original body weight.
2. Removing and recycling metals within the powdered remains.
3. Shallow-burying the powder in a biodegradable casket.
