Current practices burial and cremation, the traditional ways of dealing with human remains.
After death, a body will decay and it’s completely natural and not an direct health hazard nevertheless from the prehistoric times there has always been a strong urge to bury or cremate the deceased bodies.
With the rise of Christianity and the believe in resurrection, burial became the preferred method in ancient Europe and cremation was only used in wars and during epidemics. Modern day Cremation became a necessity in big cities in the 1800 and with the abundance of fossil fuels like coal, oil and gas.
Burial in our present day and age is stretching the limits what an area can take as it’s competing with our living arrangements and other uses of land. Cremation can take up to 40m³ of natural gas and emits nearly 2 kilo of CO2 for every m³ gas used.
With the rise of the population and the time people live the big bulge of people born during the population explosion are yet to die, presenting further pressure up the scarce resources. And so a whole arrangement of new “green” alternatives is presented.
Freezing the body with liquid nitrogen till -196 degrees Celsius and fragmenting the corpse to pieces and dry freezing it to remove moisture and bury the remains. It’s a process called Cryomation for more details see their website
An other proposed method is Resomation dissolving the human remains in potassium hydroxide(KOH) and flushing the resulting organic soup in the sewer.
According to their website it is: “Resomation is a water/alkali based alternative to burial and cremation with a number of environmental benefits and is both dignified and respectful”
With al it’s high-tech stance removed it’s simply not sustainable; the contamination of water, the irresponsible way of using potassium that is much better used as compound in fertilizer. Deposits of potassium, where it can be mined economically, are rare and deep underground.
