Okay, I just don’t see what is the supposed environmental benefit of this.
For one thing, there’s this irrational fear of carbon dioxide. Our bodies contain a lot of carbon; no matter how the disposal takes place, the carbon still exists, and is used by other living organisms that incorporate it into their bodies.
For another, dissolving the body in lye and then pouring it down the sewers seems very polluting. In a research laboratory, if I were to pour lye down the sink, I would face legal repercussions. It has to be neutralized with acid, carefully, since acid/base reactions can be quite vigorous.

There is none. Even if one were to fear CO2, it’s a natural byproduct of decomposition, which God, if you wish to look at Genesis 3:19 or if you prefer, nature desires should happen when plants and/or animals die. The bacteria which decompose life perform respiration, and release CO2 and heat as a result. In all honesty, I am going to put in my will as long as I have a say that when I die, I should decay after death, and be returned to the Earth. At least decaying and fertilizing the soil sounds better to me than getting liquified and dumped into the sewers, right?
