It seems this is finally becoming legal in Washington State, and there is a company called Recompose lined up to become the first mortuary where you can have your body composted after your death. It costs about $6k, which is pretty good compared to the cost of a traditional burial.
Doesn’t it sound nice to not waste all that energy and generate a ton of carbon dioxide, and instead end up using your remains to grow roses or a nice tree somewhere. The process apparently involves burying you in straw and wood chips for six weeks and turning regularly, and that will decompose the body including the bones into soil suitable for use in a garden. Total energy use is about one eighths of that of cremation.
Sign me up, sounds a perfect way to go.
