Flame vs. Flow: Is Water Cremation the Next Big Funeral Industry Disruptor?

DFS Memorials, affordable cremations nationwide.

Okay, I want to start today with a phrase that um honestly it feels like it shouldn’t exist. It’s like a glitch in the matrix or maybe a really bad oxymoron.

What jumbo shrimp?

Exactly. Like jumbo shrimp or deafening silence. Are you ready for it?

I am. Lay it on me.

What Is Water Cremation? Understanding Aquamation and Alkaline Hydrolysis

Water cremation. It really does stop you in your tracks, doesn’t it? It just feels like a complete contradiction.

It does. When I think cremation, I have a very, very specific image in my head. I think fire, combustion, flames, you know, ashes, but water cremation. It feels like we’re trying to break physics here, right?

But according to all the research we’ve pulled for this podcast, not only is it real, it’s causing the biggest shakeup in the death care industry in, I don’t know, a century.

That’s not an exaggeration at all. I mean, if you look at the history. For over a hundred years, the American way of death had exactly two things on the menu. You had option A, traditional burial,

casket, vault, the whole deal,

the whole thing. And option B was flame-based cremation. That was it. Those were the pillars. But what’s happening right now is what industry analysts are calling a period of structural disruption.

Structural disruption just sounds like a very polite business term for everything is changing and people are freaking out.

That’s pretty much it. And at the absolute center of that storm is this technology. we’re unpacking today. Now, its official scientific name is alkaline hydrolysis,

but you’ll see it marketed as aquamation or bio cremation, sometimes resomation.

I think I’m going to stick with aquamation. Alkaline hydrolysis is giving me flashbacks to my high school chemistry final. It’s a lot.

It is a mouthful. But the mission here isn’t just to look at some, you know, weird new machine. We’re really looking at a convergence. It’s chemical engineering meeting environmental stewardship. And it’s all colliding with this massive cultural shift in how we process grief.

So, is this just a niche science experiment for like eco-warriors?

Or is this really the future of how we

well how we die?

Well, looking at the data, it is absolutely looking like the future. It’s the necessary evolution of an industry that is literally running out of space and running into some very serious climate concerns.  But, and this is my favorite part, to understand the future of death, we actually have to go all the way back to 1888.

1888. Okay. This is the fact that just completely threw me. I assume this was some Silicon Valley tech, you know, invented 3 years ago in a lab somewhere. But you’re telling me the patent is Victorian.

That’s right. An English analytical chemist named Amos Herbert Hopson. He patented a method for processing animal carcasses using an alkaline solution. But here’s the twist. He wasn’t trying to change funerals.

He wasn’t thinking about grandma.

Not at all. He was trying to make fertilizer.

Fertilizer. So the modern brochures talking about a gentle water bath are based on a machine designed to turn farm animals into plant food.

It was purely about nutrient recycling. You have to get into that Victorian mindset. They were obsessed with industrial efficiency and chemistry.  Hopson saw that nature is well kind of slow at decomposition. If you bury a cow, it takes a long, long time. He figured if he could speed that process up, he could turn the nitrogen-rich tissues of an animal into high quality food for crops. It was just an agricultural tool.

So, it was all about getting nutrients back into the food cycle as fast as humanly possible.

Exactly.

So, how on earth do we get from Victorian farm equipment to a funeral home in 2026? That feels like a huge leap.

The History of Alkaline Hydrolysis: From 1888 Fertilizer Patent to Modern Funeral Homes

It took a long time. It tech pretty much just sat on a shelf for a century. It wasn’t until 1993 that Albany Medical College installed the first commercial scale system. But again, it wasn’t for public funerals. It was for disposing of cadavers used in medical research.

Right. I saw that in the notes. The Mayo Clinic, UCLA, University of Florida,

they all started using this way before the public heard about it. Why them? Was it just cheaper?

It was safety primarily. And this gets into the biology. The process is incredibly effective at destroying pathogens. Even prions.

Prions. Those are the weird misfolded proteins that cause things like mad cow disease.

Exactly. Creutzfeldt-Jakob mad cow. Prions are notoriously hard to kill. You can blast them with incredible heat in a standard cremation and they can sometimes survive. They’re just incredibly resilient.

But this al line process. It destroys them completely. It just unravels them.

So for a medical research facility that’s handling donated bodies, this is basically a bio-security measure.

Precisely. And there’s another benefit for a medical school. It leaves the skeletal remains incredibly clean. So if you need to return bones to a donor’s family or keep them for study, this is the best way to get them pristine without any damage.

Okay, so it’s safe enough for the Mayo Clinic. That’s a pretty good endorsement. But let’s get into the how.

I need to understand that. mechanics. You said it’s not burning. So, what is actually happening inside that tank?

It’s what’s called a reductive chemical process. So, flame cremation is oxidation, rapid burning, lots of oxygen.   This is hydrolysis. The best way to think about it is accelerated natural decomposition.

So, we’re just speed running nature.

That’s a perfect way to put it. If you were buried in the ground without a casket, the bacteria and the alkaline soil would eventually do the exact same thing. It just takes decades. This machine does the same chemical work in a few hours.

And the recipe is what? It’s surprisingly simple. A stainless steel vessel, 95% water and 5% alkali.

And alkali is what? Like lye.

Usually potassium hydroxide or sodium hydroxide. Then you just add some heat and circulation.

That mixture just dissolves the body.

Dissolves is the word everyone uses. But what’s really happening chemically is that the alkali is acting as a catalyst. It targets the peptide bonds that hold all your proteins together. It basically unzips the molecular chains.

Okay?

So, Proteins break down into simple amino acids. The fats go through a process called saponification.

Saponification. Wait a second. I remember this. Isn’t that how you make soap?

It is exactly how you make soap. The body’s fats are converted into soap and glycerol. And the DNA, it’s completely disintegrated into sugars and phosphates. There is zero genetic material left. You’re just reduced to your basic chemical building blocks.

It’s wild to think that we’re essentially just this complex arrangement of chemistry and the machine just sorts it all back. into the original bins.

It is a very humbling thought, isn’t it? It strips away all the biology and just leaves the chemistry.

How Water Cremation Works: The Science Behind Aquamation

Very.  So, let’s visualize the hardware.

I’m picturing some kind of sci-fi pod.

Is it like a sleeper tube from a spaceship?

You’re not that far off. It’s a specialized airtight vessel made of 316 L-grade stainless steel. You need that high grade to resist the corrosion. And generally, a funeral home has two choices for how they run it. High temp or low temp. Is that just like a speed setting? Gentle cycle versus heavy duty.

Sort of, but the physics are different. The high temp systems are pressurized like a giant industrial pressure cooker. They run at about 300 to 350° F.

And because of the pressure, the water doesn’t boil.

Correct. But the reaction happens fast. You can finish a cycle in maybe 4 to 8 hours,

which is incredibly fast. That’s a single work shift. You could, I don’t know, drop grandma off in the morning and pick up the remains by dinner.

Exactly. High volume facilities love those, but they’re expensive. And because they’re pressurized, They’re regulated like boilers. You need inspections, special operators.

Then you have the low temp systems. These run at atmospheric pressure, so no danger of explosion at about 200°, just below boiling,

but I’m guessing it takes a lot longer without the pressure.

Much longer. We’re talking 14 to 18 hours. It’s the low and slow method, but they’re cheaper to install, easier to get permits for.

Okay, we have to address the elephant in the room. This is the question I feel like every listener is probably screaming right now. You put a body in, you add water and chemicals, You wait, you open the door. What happens to this stuff?

The soft tissue. Where does it go?

This is what the industry calls the “icky factor”. And honestly, it’s the biggest hurdle in public perception. The soft tissue becomes what is technically called effluent.

Effluent. That sounds

Yeah.

extremely clinical.

It is. It’s a sterile coffee colored liquid. It has the consistency of soapy water. And chemically, it’s just a solution of amino acids, sugars, salts, and soap. It’s totally organic. There’s no tissue left, just the chemical components of tissue.

And where do they put it?

In most cases, it goes right down the drain into the municipal wastewater system.

I can just hear people recoiling. “You’re putting grandma into the sewer.”

It sounds harsh when you say it that way. And that visceral reaction is exactly what opponents latch on to. It feels disrespectful. But if we look at it from the perspective of say a wastewater treatment plant engineer,

this is actually good stuff.

How could it possibly be good? It’s human remains.

Water Cremation vs Flame Cremation: Key Differences in Remains and Process

Well, remember, wastewater plants use bacteria to break down waste. This effluent is nutrient-rich organic material. It’s like an energy drink for those bacteria. It actually helps the plant work better. The only technical issue is the pH.

Right. Because of the alkali.

Exactly. The liquid comes out very basic, a high pH of around 11 or 12. So before they release it, they usually bubble carbon dioxide through it. That neutralizes it right down to the level of normal tap water.

So by the time it actually hits the sewer system, it’s just neutral,  soapy water with some extra nutrients.

Precisely. And to bring it full circle back to 1888, in some specific cases, maybe on conservation land, that effluent can be used as fertilizer.  It’s rich in potassium and nitrogen. You’re literally returning the nutrients to the earth.

That is kind of poetic. Yeah.

But for the family, they don’t get the liquid. They get the remains. And this was another thing that surprised me. The difference between ashes from fire and ashes from water.

It’s a striping visual difference. If you’ve ever seen cremated remains from a flame cremation. They’re usually gray, gritty, kind of like coarse sand. They can be charred. That’s the oxidation at work,

right? It looks like ash from a fireplace mixed with gravel.

With Aquamation, the remains are pure bone calcium phosphate. They come out incredibly clean. We’re talking pure white to a light tan. And because there’s no fire, there’s no carbon, no char.  When they process them into a powder, it doesn’t look like grit. It looks like fine flour. It’s very soft.

And the sources mentioned there’s more of it, too.

Significantly more families can get 20 to 32% more remains back compared to a flame cremation.

Why? I mean, bone is bone, right? How is that possible?

Think about a flame cremation. You have this turbulent hot air blasting up a chimney. You inevitably lose some of that fine particulate matter, some of the ashes right out the stack. It just goes into the atmosphere.  With water, it’s a closed loop. Nothing leaves the vessel. So, you retain 100% of the skeletal mass.

So, practically speaking, you actually need a bigger urn.

You do. It’s a detail funeral directors actually have to warn families about that standard ern might be a tight fit.

That is just wild. Let’s talk about the branding of this gentle death care.

It seems like the marketing is really leaning into the psychology of water versus fire.

That’s the core emotional pitch. Fire is viewed by many as well violent. It burns. It destroys. Water is viewed as cleansing.  A warm water bath. It feels more natural.

It sounds like a spa treatment.

And that’s intentional. And it isn’t just cynical marketing. It appeals very strongly to a specific group. Parents of infants or stillborn babies.

Oh wow. I hadn’t even thought of that. That hits hard.

The idea of putting a small child into a fire is often just intolerable for grieving parents. It feels aggressive, final in a scary way. The concept of water feels much softer, more maternal.  It completely changes the emotional landscape.

That makes total sense. It’s a softer exit. But let’s pivot to the cold hard cash because this is an industry. Funeral homes are businesses. Why are they investing in this? I tell the price tag. It is not pocket change.

The Cost of Water Cremation: Why Funeral Homes Are Investing in Aquamation

No, it’s a massive investment. A single machine can cost anywhere from $175,000 to over $330,000 and you need to reinforce the floor. You need special plumbing, permits. It’s a huge capital expense.

So, why do it? Why take on that kind of debt if you already have a perfectly good cremation oven?

Because of something the analysts call the ‘cremation cliff’.

That sounds ominous.

It is. If you’re a funeral homeowner, look at the stats. By 2045, the cremation rate in the U.S. is projected to at 82.3%. The problem is cremation makes way less money than a traditional burial. There’s no expensive casket, no embalming, no plot, no headstone.

So their revenue is just tanking because everyone is choosing the cheaper option.

Exactly. They’re watching their margins evaporate. They need a premium product, something they can charge more for that feels different from the standard cremation. Aquamation is that premium product.

Environmental Benefits of Aquamation: Carbon Footprint, Mercury, and Energy Use

How much more are we talking?

The average cost to the consumer is around $2,500. A direct flame cremation might only be $1,000, maybe $1,500. So, it allows the business to upsell in a big way.

But does it cost them more to run? I mean, am I eating that profit in utility bills?

And that’s the beauty of it for the business owner. It costs a fortune to buy, but pennies to run. Flame retorts use huge amounts of natural gas. Aquamation uses electricity and the energy cost per cycle is about 90% less.

90% less. That’s a huge margin.

Huge. Plus, think about maintenance. Flame retorts are ovens. They have specialized bricks inside that wear out and cost thousands to replace.  These are just stainless steel tanks. They can last 25 years with minimal upkeep.

So, it’s a long-term play. High upfront cost, low operating cost, and a higher price point for the family.

Precisely. It solves the economic problem of the cremation while also solving the environmental problem.

And that leads right into the biggest selling point, probably the one that gets the most press, the environment. We talked about energy, but what about the broader impact?

This is the green argument, and it is statistically very strong. Aquamation reduces the carbon footprint of disposition by about 90% compared to flame cremation. You’re not burning fossil fuels. You’re not releasing greenhouse gases.

And I read something about mercury. I didn’t realize flame cremation was a mercury issue.

It’s actually a major source of airborne mercury pollution. It comes from dental fillings, the old amalgam fillings.

Oh, right. The silver fillings.

When you burn a body, that mercury vaporizes and goes right out the chimney into the atmosphere. Then it settles in the water gets into the fish we eat.  In aquamation, the mercury stays solid. It just sinks to the bottom.

So, you can just scoop it out.

You can collect it and recycle it. And it’s not just mercury. This is one of the wildest details in implants.

Yeah. Pacemakers and hips.

Pacemakers, artificial hips, titanium pins, you name it. In a flame cremation, pacemakers are a nightmare. They have lithium batteries. If you put one in the oven, it explodes. It can destroy the brick work. It’s dangerous for the staff.

Exploding pacemakers that It’s not good.

Not good at all. So, directors have to cut them out beforehand. But in Aquamation, you just leave them in. The process doesn’t touch metal or plastic. At the end, you just reach in and pick out a perfectly clean sterilized titanium hip joint. It can actually be recycled.

So, we have a cheaper to run machine, a greener process, a solution for medical waste, and a gentler sell the families.  Sound like a slam dunk. So, why isn’t this everywhere? Why can’t I just go down the street and get this done?

Is Water Cremation Legal? State Laws, Religious Opposition, and Future Adoption

Because we live in a complex society. with deep religious and legal roots. The technology is ready, but the culture is still fighting it out. The growth is largely being driven by the NONEs.

The NONE [None Religious, No denomination]

Yep. Secular Americans. People who check none on the religious affiliation box on a survey.

Yeah.

They don’t have loyalty to traditional religious burial rights. So, they’re open to new options. And that group is growing fast. But not everyone is a nun.

I’m guessing traditional institutions might have some strong thoughts on this. The Catholic Church is the biggest one. In 2023, the US Conference of Catholic Bishops issued a statement officially opposing alkaline hydrolysis.

And what’s their core argument? Is it the science?

No, it’s about dignity. It comes right back to that liquid we talked about. They argue that the human body is a temple of the Holy Spirit. And they believe that pouring the dissolved remains of a body down a drain into a sewer system, it just doesn’t show the required respect for that temple.

So for them, the end result, the clean bones, doesn’t justify the means the sewer.

Correct. To them, flushing the remains, even if it’s chemically sterile, is indistinguishable from flushing waste. They believe the body has to be treated with reverence through the entire process.

And that religious push back isn’t just theoretical. It translates directly into laws.

It certainly does. The legal map of the U.S. on this is a complete patchwork quilt right now. As of 2026, it’s legal in about 28 states. You’ve got states like Pennsylvania and Virginia that are finalizing rules to allow it.

[State-by-State Guide to where Aquamation is legal]

But then you have the hard no States. Take Texas. Texas has explicitly prohibited it. And that’s not an accident.

Yeah.

That is largely due to very successful lobbying by religious groups and frankly traditional funeral entities who want to preserve the sanctity and the economics of the traditional funeral.

It’s just wild how geography can dictate your final options. You could live on one side of a state line and have this and 5 miles away it’s illegal.

That’s the reality. It’s highly localized. But looking at the broader picture, the trend lines are clear. The market for this is projected to grow over 11% a year. It’s moving from the fringe to the mainstream because those environmental pressures, they aren’t going away.

So, bringing this all together, we started with this contradiction, water cremation.

But what we’re really looking at is a fundamental shift in how we view our own biology.

I think that’s the key takeaway. Aquamation is moving from being a medical technology to a commercial reality.  And it’s happening because we are being forced to confront resource scarcity. We’re running out of land for burials. We’re trying to cut carbon. This technology forces us to decide what stewardship really looks like for the dead.

It’s fascinating to me how the marketing uses words like warm bath to sort of hide the fact that this is very serious industrial chemistry. It’s like we need the soft language to accept the hard science of it all.

We do. We’re biological creatures. We’ve always struggled with what to do with the vessel when life is gone.  But as land gets more scarce, as carbon taxes become a reality, this isn’t just a trend. I really believe this is the future of the final act.

Which leaves us with a really big question to chew on. If we accept that our bodies are just biological vessels, where does the dignity of death actually lie? Is it in preserving that vessel in a box for as long as possible? Or does dignity lie in how efficiently we return those nutrients back to the earth to support new life?

That is the ultimate question. Is a good death one that lasts forever or one that feeds the future?

Something to think about. That’s it. for this podcast. Thanks for listening.
