“Think About Death” the inscription at the Gothenburg cemetary reads.
Remember the story a few years back about an environmentally-friendly form of burial that sifted the toxic and valuable metals from corpses and put resulting nutrient-rich dust into biodegradable caskets to replenish the earth as compost?
OK, maybe you haven’t heard. But this type of eco-burial was the passion of researcher and business owner Susanne Wiigh-Mäsak, who formed a company, Promessa Organic AB, to help dead people that wish to quickly return to the earth. According to Wiigh-Mäsak, her method is much more sustainable than our current embalming in caskets, or cremation. Traditional casket-buried bodies are deeply buried, rot slowly and release methane as they do so, Wiigh-Mäsak has said. With Promessa’s process, powdered bodies will be shallowly buried and break down much more quickly.
Except that in Sweden, the freeze-drying and shallow burial of corpses has no precedent, so this new form of eco-burial has yet to go forward.
Thus the body of Jane Günther, who had herself frozen upon her death in 2009, is still waiting (thus far in vain) for the Swedish state to comply with her last wishes. Recently, the Swedish Tax Authority threatened to force conventional burial of Günther’s body against those wishes, as it seems there’s a legal limit for how long corpses can remain unburied.
Gunther is one of 12 Swedes to undergo the deep-freeze in anticipation of a Promessa-style eco-burial, while Wiigh-Mäsak waits for approval of her technique.
The main problem is that Swedish law only allows for two forms of burial – cremation, or burial in a casket. At Promessa, a body is first chilled down to -18C. Once she’s obtained permission for her process, Wiigh-Masäk’s clients will be dunked in liquid nitrogen (obtained as a byproduct of the medical industry) which freezes them to -196C. Wiigh-Mäsak says this makes a body very brittle, and subsequent agitation causes the body to break apart and eventually disintegrate. Heavy metals are then filtered out by means of magnets, and the remains put into a biodegradable corn casket and buried in a shallow grave. Wiigh-Mäsak says in 6 – 12 months the body will be rich compost.
“Whether we burn our body or bury it six feet under, we neglect the possibility of bringing our organic remains back to nature, thereby becoming part of a balanced process.” – Susanne Wiigh-Mäsak
Researcher Bengt Johansson isn’t convinced that the method will work. Wiigh-Mäsak has said she’s tested the method on hundreds of pigs, but she hasn’t publicly shared her research findings.
Johanssom, a professor of anatomy at Sweden’s Sahlgrenska Academy who has worked with freezing technology, told a Swedish newspaper he doesn’t believe bodies will react in the way Wiigh-Mäsak says they will, and wants further scientific, peer-reviewed proof.
So it’s a fight to the death, or beyond.
Wiigh-Mäsak is planning to build a Promessa facility this year to handle more burials with her method, which she calls promession.
