Methods of cheaply disposing of the recently departed without polluting the environment & using up wood for coffins, or filling the air with smoke from cremations, get steadily more bizarre :
Promessa, in Sweden, has come up with a method of burial that negates the worst aspects of the disposal of remains. They want to freeze human bodies, then shatter them into a million pieces. The body is chilled to around negative 18 degrees Celsius. Once it's cold enough, it's submerged in liquid nitrogen. As the body becomes colder, it gets more brittle. Once it's brittle enough, it's shocked with soundwaves that crumble it into powder.And that's just the start.
And that's just the start.
