OREANDA-NEWS.Washington was the first who signed the law providing for the introduction of a new method of dumping people - composting. 

Biologist Susanna Viig-Masak about 20 years ago patented the technology of producing humus by cooling. The material was frozen in a chamber with liquid nitrogen, and then crushed in a mill. After some time, it was added to a biodegradable container and buried in the ground at a depth of up to 25 cm. Near it they planted any plant so that its roots reached the fertilizer. Some experts consider freezing the human body in a promising way. 

American scientists representing the University of Washington in 1998 proposed using a method of composting for the burial of human remains. During the study, the corpse was placed in a capsule with wood chips, a sweet solution was poured in and aerated to create conditions for the growth of bacteria. Other experts said it was possible to bury the dust of a person under a tree to fertilize it.
