“The method is based upon preserving the body in a biological form after death, while avoiding harmful embalming fluid. Then it can be returned to the ecological cycle in a dignified manner as a valuable contribution to the living earth,” explains Susanne Wiigh-Mäsak, biologist and head of operations at Promessa Organic AB. An important part of the solution is to remove that which is least important; the water that makes up 70 percent of a normal-sized body. Technically speaking, this is done using an entirely closed individual process in which the corpse is freeze-dried in liquid nitrogen. Within a week and a half after death, the corpse is frozen to minus 18 degrees Celsius and then submerged in liquid nitrogen. This makes the body very brittle, and vibration of a specific amplitude transforms it into an organic powder that is then introduced into a vacuum chamber where the water is evaporated away. The now dry powder then passes through a metal separator where any sur
