Green burials are a popular way to a person's funeral in order to provide a non inhibiting way for the body to decompose. Many of these green burials use burial shrouds. A burial shroud is an item, generally cloth, that is used to wrap the body when it is buried.
Shrouded funerals are considered green because they allow easy decomposition in a very natural way. More importantly, people find a comfort in the shrouds.
