There are many beautiful, beneficial ways to return to the earth! Human Composting “is an accelerated form of decomposition by which a corpse is placed in a vessel with wood chips, alfalfa, and straw. Oxygen is pumped in to increase thermophilic, or heat-loving microbial activity.”
As it is a relatively new method of experimentation, the cost runs around $5,500. In about 30 days time, the compost becomes a couple cubic yards of EPA approved soil.
Another green burial option is to become a Living Urn. This process uses ashes from cremation to be mixed in a potted tree of choice. Over time, the ashes nourish the tree and provide vital nutrients to it’s growth.
The Green Burial Council has additional, useful information for green burial options.
