Swedish biologist Susanne Wiigh-Mäsak is the founder of Promessa Organic AB, the developer of promession. “Promessa,” the Italian word for “promise,” touts promession as a gentle, ecologically-friendly body disposition option that ethically addresses the protection and preservation of our natural resources, including land space. Promession produces an organic powder that reintroduces carbon into the soil and should not be confused with cryogenics, a process that also utilizes freezing to preserve the body rather than reduce it to fertile remains. 


The Promession process begins with cooling the body to – 0.4ºF. The body is then placed in the Promator (promession machine) and frozen with liquid nitrogen to – 320ºF. Once frozen, the body becomes very brittle and easily reduced, via gentle vibration, to an odorless powder. Any dental fillings, pacemakers, implants, or other medical devices are left behind and separated out before the powder remains are placed in a bio-degradable container. The container and remains, once buried in shallow soil, will degrade to mulch in approximately six to 18 months. Promessa describes their process as allowing the deceased to be “One with nature, for eternity.”


Despite being developed by Wiigh-Mäsak 20 years ago, promession is not yet available. Efforts to raise awareness of the process in the U.S. have resulted in five U.S.-based Promessa representatives/franchisees (to date) actively working to educate the public and legislators on its benefits. Promessa continues to invite interested people to pursue representative opportunities in the U.S., in an effort to have all 50 states advocating to bring promession to the U.S.

What are you questions or concerns about Promession? How do you view it as an alternative to cremation or resomation? Would you choose it for yourself or a loved one if/when it becomes available in the U.S.?
