It starts from the moment you pass. Your organs begin to shut down. Hair stops growing, skin recedes. Some parts of the body take longer than others, but eventually, as with all things, it all starts to break down.

If you opt for a traditional burial, your remains will spend years nestled within a casket underground, progressing into a deeper state of decomposition. If you opt for a traditional flame-based cremation, you eliminate any further decomposition by burning it to a halt.

But there's also another alternative -- one designed to accelerate the decomposition process through the medium of water. It's known as alkaline hydrolysis, or water cremation. One part spa, one part chemical blend, a few hours of a swirling soak, and your earthly remains are no longer.

There are undeniable benefits to this process. In 2011, a study from the University of Groningen compared conventional burial, cremation, alkaline hydrolysis and cryomation and found that alkaline hydrolysis had the lowest overall environmental footprint.
