The idea of promession involves five steps:
# [[Coffin]] separation: the body is placed into the chamber
# Cryogenic freezing: [[liquid nitrogen]] at −196 [[°C]] crystallizes the body
# Vibration: the body is disintegrated into particles within minutes
# Freeze drying: particles are freeze dried in a drying chamber, leaving approximately 30% of the original weight
# Metal separation: any metals (e.g.,&nbsp;tooth [[Amalgam (dentistry)|amalgam]], [[Hip replacement|artificial hip]]s, etc.) are removed, either by magnetism or by [[Sieve|sieving]]. The dry powder is placed in a [[Biodegradation|biodegradable]] casket which is interred in the top [[Soil horizon|layers of soil]], where aerobic bacteria decompose the remains into [[humus]] in as little as 6–12 months.
