Promession: The Most Ecological Way to Bury Our Dead?

The final product of over 20 years of research and testing from Swedish scientist Susanne Wiigh-Mäsak, promession is a new, eco-friendly burial option for those wishing for their corpse to leave the smallest ecological impact possible. Concerned with the negative impact current burial practices have on the environment, Wiigh-Mäsak came up with this method to return our bodies to the ground in a way that gives nutrients back to the earth instead of damaging it.

There are several steps to promession. The first occurs after the funeral services or ceremonies have taken place and the body is placed into the Promator machine. Once there, the body will be frozen using liquid nitrogen to -196° C (or -321° F). This process takes about two hours, and all of the liquid nitrogen used will evaporate into the air harmlessly. After it has been frozen, the body will then be transported onto a belt, which will use ultrasonic vibrations to shatter the body into tiny, millimeter-sized pieces. It only takes one minute to break the body down in this way. Next, the body is placed into a vacuum chamber where the remaining water is extracted from the body and which will then evaporate into the air. After this, only 30% of the body’s total composition remains. The remaining dry particles go through electrical currents which will remove any metal left in the body (such as dental fillings and prosthetic hips), and this metal will then be recycled. Finally, the remains are placed into a small, bio-degradable coffin, which is then buried very shallowly. The body and coffin will be completely decomposed within 6-12 months, which can be contrasted to the several years it can take for a typical burial.

As someone who tries to live in an environmentally-conscious way, I find this method of burial very attractive. However, with all the expensive equipment and technology that is used, I could easily see this being an extremely expensive way to be buried.
