resomation
Meet Amy. In a few hours Amy will be coffee-colored liquid with the consistency of motor oil and a strong ammonia smell. She will then be poured down the drain.
But we are getting ahead of ourselves.
Amy is 34 and works at an investment bank. She is a keen environmentalist. Amy bikes to work, does not eat meat and recycles. The environment is such a big part of Amy’s life, she’s not only interested in living green. She wants to die green.
This is how Amy's final day will go.
There is no service, no viewing of Amy, she is taken to a resomation facility on an industrial estate.
Amy's naked body is placed in a porous metal basket that will allow fluid to exchange throughout her resomation cycle.
The basket is slid on teflon rails into the resomator. In concept, the resomator is a mechanical stomach where Amy will be digested into soft, soapy and wet bone remains and liquefied tissues.
The integral load cells weigh Amy, and the appropriate amount of water and alkali are added automatically to the vessel. 500 litres of water mixed with potassium hydroxide (a strong alkali pH 14) in a 1:21 ratio are used to dissolve Amy away. Gas-powered steam generators build up pressure within the vessel as the temperature rises up to around 170 degrees Celsius. Amy is not boiled because the pressure in the vessel is sufficiently high that the water does not boil.

All Amy's tissue, muscle, hair and nails dissolve. A re-circulation pump creates a whirlpool effect that helps Amy to dissolve. The alkali digests Amy by the forced insertion of water molecules into her proteins, fats, carbohydrates and genetic material. In this way it dissolves her tissues. Amy's DNA is totally broken down to its constituent compounds, and her proteins to amino acids and a few very small peptides. The fat in her body is decomposed to fatt acids.

The whole process is like a (very) hot bath in which the alkali eats away at Amy. It takes about 30 minutes to dissolve Amy's tissues once the alkali gets going, and the time for the whole process is about an hour.
Amy's resomation is controlled by a Siemens touch-screen and PLC. (Programmable Logic Controller - a device used to automate monitoring and control of industrial equipment). The PLC collects all the data about Amy's dissolution and allows downloading of this information to a remote PC. The unit also allows any faults to be diagnosed via the Internet.
After an hour of the resomation experience Amy has disappeared totally. Calcium phosphate outlines of her bones remain. The calcium phosphate is very soft and can be crushed in the hand. This wet, soft and soapy bone residue must be dried (under a heat lamp overnight) before it can be pulverized. The calcium phosphate is great fertilizer, and gets spread over rose bushes.
Amy's filling can be clearly seen and picked out. If Amy had any metal implants these would be in excellent condition and could be removed and recycled.
Also remaining are many litres of a liquid containing building blocks Amy was made from: amino acids, peptides, sugar and mild soap. The liquefied tissue and chemicals are pre treated with additional chemicals to balance the PH before it is flushed out of the resomation unit into the local sewer system.

Amy has been reduced to liquid spread throughout the sewer system, and to calcium phosphate that has been spread over the ground and washed away by rain. It was like she never existed. There is no physical record of her left.

Resomation has all the advantages of cremation:
Amy would be frozen down to -18 C. Her coffin would then be lowered into liquid nitrogen. At this point she becomes very firm and brittle. Amy's coffin is exposed to light vibration. She shatters into dust.
