New idea in mortuary science: Dissolving bodies with lye

2008-05-09 07:15:16

Since they first walked the planet, humans have either buried or burned their

dead. Now a new option is generating interest dissolving bodies in lye and

flushing the brownish, syrupy residue down the drain.

The process is called alkaline hydrolysis and was developed in this country 16

years ago to get rid of animal carcasses. It uses lye, 300-degree heat and 60

pounds of pressure per square inch to destroy bodies in big stainless-steel

cylinders that are similar to pressure cookers.

No funeral homes in the U.S. or anywhere else in the world, as far as the

equipment manufacturer knows offer it. In fact, only two U.S. medical centers

use it on human bodies, and only on cadavers donated for research.

But because of its environmental advantages, some in the funeral industry say

it could someday rival burial and cremation.

"It's not often that a truly game-changing technology comes along in the

funeral service," the newsletter Funeral Service Insider said in September. But

"we might have gotten a hold of one."

Getting the public to accept a process that strikes some as ghastly may be the

biggest challenge. Psychopaths and dictators have used acid or lye to torture

or erase their victims, and legislation to make alkaline hydrolysis available

to the public in New York state was branded "Hannibal Lecter's bill" in a play

on the sponsor's name Sen. Kemp Hannon and the movie character's sadism.

Alkaline hydrolysis is legal in Minnesota and in New Hampshire, where a

Manchester funeral director is pushing to offer it. But he has yet to line up

the necessary regulatory approvals, and some New Hampshire lawmakers want to

repeal the little-noticed 2006 state law legalizing it.

"We believe this process, which enables a portion of human remains to be

flushed down a drain, to be undignified," said Patrick McGee, a spokesman for

the Roman Catholic Diocese of Manchester.

State Rep. Barbara French said she, for one, might choose alkaline hydrolysis.

"I'm getting near that age and thought about cremation, but this is equally as

good and less of an environmental problem," the 81-year-old lawmaker said. "It

doesn't bother me any more than being burned up. Cremation, you're burned up.

I've thought about it, but I'm dead."

In addition to the liquid, the process leaves a dry bone residue similar in

appearance and volume to cremated remains. It could be returned to the family

in an urn or buried in a cemetery.

The coffee-colored liquid has the consistency of motor oil and a strong ammonia

smell. But proponents say it is sterile and can, in most cases, be safely

poured down the drain, provided the operation has the necessary permits.

Alkaline hydrolysis doesn't take up as much space in cemeteries as burial. And

the process could ease concerns about crematorium emissions, including carbon

dioxide as well as mercury from silver dental fillings.

The University of Florida in Gainesville and the Mayo Clinic in Rochester,

Minn., have used alkaline hydrolysis to dispose of cadavers since the mid-1990s

and 2005, respectively.

Brad Crain, president of BioSafe Engineering, the Brownsburg, Ind., company

that makes the steel cylinders, estimated 40 to 50 other facilities use them on

human medical waste, animal carcasses or both. The users include veterinary

schools, universities, pharmaceutical companies and the U.S. government.

Liquid waste from cadavers goes down the drain at the both the Mayo Clinic and

the University of Florida, as does the liquid residue from human tissue and

animal carcasses at alkaline hydrolysis sites elsewhere.

Manchester funeral director Chad Corbin wants to operate a $300,000 cylinder in

New Hampshire. He said that an alkaline hydrolysis operation is more expensive

to set up than a crematorium but that he would charge customers about as much

as he would for cremation.

George Carlson, an industrial-waste manager for the New Hampshire Department of

Environmental Services, said things the public might find more troubling

routinely flow into sewage treatment plants in the U.S. all the time. That

includes blood and spillover embalming fluid from funeral homes.

The department issued a permit to Corbin last year, but he let the deal on the

property fall through because of delays in getting the other necessary permits.

Now he must go through the process all over again, and there is gathering

resistance. But he said he is undeterred.

"I don't not know how long it will take," he said recently, "but eventually it

will happen."
