The news below comes from Inhabitat. If this information is accurate this is "legal in thirteen states: Colorado,
Florida, Georgia, Idaho, Illinois, Kansas, Maine, Maryland, Minnesota,
Missouri, Oregon, Vermont, and Wyoming."
Brace yourself. You've been warned:
"A Canadian funeral home called Hilton’s AquaGreen Dispositions is the first in Ontario to use a pioneering “flameless” cremation method
to dispose of dead bodies. Unlike a conventional cremation, the process
does not release carbon dioxide or other pollutants into the
atmosphere, instead using a combination of water, salt, and potash to dissolve organic material into a sludge that can be filtered and then safely disposed of using the existing sewer system.
The solution used to dissolve the body is heated to about 300 degrees,
hot enough to destroy any microbes or infectious prions present in the
body, so that there is no health risk from being exposed to the remains.
As such, it can simply be treated with normal sewage." [emphasis added]
