I just became aware of the process called promession through the RSS feed of the excellent worldwidewords.
This is an ecological alternative to cremation or burial. The corpse is frozen in liquid nitrogen and then shattered into powder by ultrasonic vibration before being buried in a biodegradeable box in a shallow grave. Green campaigners believe the technique could ease the crowding in graveyards and the increasingly harmful emissions from cremations.
The inventor, the Swedish biologist Susanne Wiigh-Masak, claims that the process is good for the environment because the powder (which is essentially compost) breaks down in the soil more thoroughly and quickly than by conventional burial. She suggests that relatives plant a tree or bush above the grave as a long-term memorial.
A quick google search indicates that this idea has been around a while, but, like I said, it is the first I have heard of it.
I can imagine that this might have a certain appeal to geeky types (the liquid nitrogen and ultrasonics aspects) and for those who are environmentally conscientious (the composting and tree planting aspects). It might also have some appeal in places like Japan where I have heard that there is little land for conventional burials.
