A Swedish company has come up with a different approach to dealing with bodies after people die – freeze drying – that turns out to be one of the greenest ways to go.
The body is cooled to around -18°C and then submerged in liquid nitrogen. As the body becomes colder, it gets brittle enough that when shocked with soundwaves it will crumble into powder. The powder is then put in a vacuum chamber, which instantlyboils away all the water, reducing the mass by about 70%.
