Nowadays everything is going green, even funerals.
GREEN FUNERALS: Putting Aside Embalming And Tombs.
The Promessa Foundation takes organic burial a step further...
The corpse is freeze-dried in liquid nitrogen, then vibrated until it breaks down into an organic powder, and then, in a vacuum chamber, the water is evaporated away.
The resulting dry powder is ready to be laid in a biodegradable (mulch able) coffin. In about 6-12 months time, the coffin and it's contents become compost.
Freeze-dried people make good mulch.
