Green burial is an alternative to 6' under in a vault.
Three types of cemeteries are certified by the GBC*:
hybrid, an area within a conventional cemetery where burial occurs without a concrete vault, chemical embalming, and with a biodegradable container,
natural, where all three elements are employed in a cemetery dedicated to natural burial, and
conservation, where a land trust entity preserves land that is in part used for burial.
