Liquefication, promession & the mushroom death suit

Have you ever considered the manner in which your body is disposed of when you die? Often I have pondered my existence on this comparatively tiny blue planet of ours, but never have I really considered this.

Until recently I thought that there were really only two options, burial and cremation, but prompted by a recent article by Neil Bowdler on the BBC News website, I started to research the subject in more depth, and now I realise that body disposal has become quite creative.

In his article, titled “New body ‘liquefaction’ unit unveiled in Florida funeral home‘ neil describes a device which works by:

Submerging the body in a solution of water and potassium hydroxide which is pressurised to 10 atmospheres and heated to 180C for between two-and-a-half and three hours.
Body tissue is dissolved and the liquid poured into the municipal water system. Mr Sullivan, a biochemist by training, says tests have proven the effluent is sterile and contains no DNA, and poses no environmental risk.

Whilst it may seem macarbe, this technique is far more environmentally friendly that tradition cremation techniques. For example, through the use of cremation, a single person can contribute over 200kg of air emissions.

In contrast to this method, Neil also discusses an alternate approach titled ‘Promession’. Promession is the brain child of a Swedish biologist named Susanne Wiigh-Masak, and is likened to a method of composting.

Promession is described as:

The process involves a fully automated and patented machine. Coffins are fed in one end, and the body removed from the coffin within the unit and then treated with liquid nitrogen.

The body is then vibrated until the body fragments, after which the remains are dried and refined further, and then passed through filters to remove metals, including dental amalgam. The remains are then poured into a square biodegradable coffin, again automatically, for shallow burial.

The combination of the tiny body fragments and the square biodegradable coffin, results in a smaller burial plot and hastens the decomposition process. Whilst I like the sound of my body getting so jiggy with it, that it breaks into thousands of pieces allowing for bite sized morsels for all sorts of soil bacteria and underground creatures, it is nowhere near as cool as the mushroom death suit!

The mushroom death suit is the work of an artist by the name of Jae Rhim Lee. Basicallly, it is a body suit embroidered with thread infused with mushroom spores. The design of which is inspired by the dendritic growth of mushroom mycelium.

According to Jae Rhim Lee the suit:

Is accompanied by an Alternative Embalming Fluid, a liquid spore slurry, and Decompiculture Makeup, a two-part makeup consisting of a mixture of dry mineral makeup and dried mushroom spores and a separate liquid culture medium. Combining the two parts and applying them to the body activates the mushroom spores to develop and grow.

The project is currently growing and training various mushroom cultivars in the hope of producing what she refers to as the ‘infinity mushroom’.

Jae Rhim Lee is training fungi to consume her own body tissue and excretions–skin, hair, nails, blood, bone, fat, tears, urine, feces, and sweat. The fungi have been chosen for their potential to utilize the nutrients in human tissue and to remediate industrial toxins in soil.

How do you plan to go in the end?
