As the movement toward greener, more natural burials gains steam, a Swedish biologist who specializes in soil production thinks she's got the best method, reports the Walrus magazine. It's called promession, and it's a doozy: Corpses are frozen with liquid nitrogen, then shattered into tiny pieces on a vibrating table. A vacuum removes moisture, and the tiny bits are buried in shallow topsoil in a bag made of corn starch. In a few months, nothing is left.
“We wanted to make the body unrecognizable without using any kind of an instrument that you would see in a kitchen or garage,” said the biologist. The first so-called promatorium opens soon in Sweden, and she has hopes to expand worldwide. Still, "people may be leery of this new fandangled technology," said an advocate of natural burial, but of a type that doesn't involve liquid nitrogen.
