Unlike traditional burials, which involve embalming fluids, metal caskets, and concrete vaults, natural burials are based on the concept of returning the body to the earth in a biodegradable manner. In a natural burial, the body is not embalmed, allowing it to decompose naturally. This not only eliminates the need for toxic embalming fluids, but also allows the body to return to the earth in a more natural and eco-friendly way. The use of biodegradable materials is also a key component of a green burial. Instead of metal caskets and concrete vaults, natural burials utilize biodegradable caskets or shrouds made from materials such as bamboo, wicker, or recycled cardboard.
