“Chemical disposal of...”

I was much impressed by the letter "Chemical disposal of the dead” (Readers’ Forum, Parsiana, April 7, 2015) by Dr Syrus Darvish Irani.
I have read earlier that body parts are burned. The work must be very gruesome for the nassessalars. If chemicals really help in quick disposal of bodies, I would like to register myself for the same so that my body is disposed of with dignity.
