As a former sewer plant worker, I’m here to tell you that it’s true that they’ll put anything down the sewer. But this effort to liquify human remains and then send it down the sewer is one for the sludge books.
It seems one funeral home in Ohio started doing this before the health department intervened. The British are looking into it. Some say the process is environmentally friendly because it reduces air pollution from crematoriums. But there are a lot of other issues.
I could be wrong, but I don’t think this process will fly. For one thing, it appears that the liquifaction process requires addition of alkali (lye, sodium hydroxide, etc.) Without going into the chemistry, discharging this type of solution to a sewage system is not permitted by all sorts of sewer use ordinances on the local, state and EPA federal level. So, to those who are promoting this process, it’s back to the drawing room.
