Abstract: An environment-friendly corpse treatment apparatus comprises: a drying portion for removing moisture contained in a corpse; a pulverization portion for applying an impact to the moisture-removed corpse to pulverize the same into small pieces; and a foreign matter separation portion for separating a foreign matter contained in the pulverized corpse. The corpse loaded at the drying portion is dried in a vacuum state. The apparatus is environmentally friendly since a pollutant such as a toxic exhaust gas or dioxin is not generated, soil is not contaminated when a corpse is buried. A treated corpse is appropriate for natural burial or woodland burial since the treated corpse can be used as a nutrient. A corpse can be used as manure or feed if the corpse is animal waste.
