The Gentle Alternative: Understanding Water Cremation Ashes
Water cremation ashes are the powdered remains resulting from alkaline hydrolysis, an eco-friendly alternative to flame-based cremation. For funeral directors seeking quick information:
| Water Cremation Ashes: Key Facts |
|---|
| • 32% more volume than flame cremation ashes |
| • Fine, white powder (primarily calcium phosphate) |
| • No DNA or tissue remains after processing |
| • Safe for scattering, burial, or memorial products |
| • Produced through alkaline hydrolysis (using water, heat, and alkali) |
| • Legal in approximately 26 U.S. states (as of 2024) |
Water cremation, also known as aquamation or alkaline hydrolysis, is gaining popularity as families seek gentler, more environmentally conscious end-of-life options. The process uses warm water and alkali instead of fire to accelerate the body's natural decomposition, resulting in sterile remains that are kinder to our planet. While the concept might seem new, the technology has existed since 1888 and has been used in medical facilities since the 1990s before becoming available to the public in 2011.
"If more people respect the planet in death, it bodes well for how they'll treat it while they're still alive," notes one industry professional, highlighting the growing awareness of environmental impacts in end-of-life decisions.
I'm Mortuary Cooler, a national supplier of mortuary equipment with experience in water cremation systems and handling water cremation ashes. My work with funeral homes transitioning to alkaline hydrolysis has provided knowledge of how water cremation ashes differ from traditional remains and the specialized equipment needed for this innovative process.
Water cremation ashes terms explained:
Understanding Water Cremation Ashes
As we talk with funeral directors from New York to Los Angeles, we've noticed a surge in questions about water cremation. The science behind water cremation ashes is truly remarkable, offering a gentle alternative to traditional flame-based methods.
Alkaline hydrolysis works with nature rather than against it. The process uses a solution of 95% water and 5% alkali (usually potassium hydroxide) to accelerate what would naturally happen during decomposition. This gentle mixture, combined with warm temperatures and sometimes a bit of pressure, helps return the body's soft tissues to their basic elements – simple amino acids, peptides, sugars, and soaps.
What's left behind are the inorganic bone minerals, primarily calcium phosphate. These minerals become what we call water cremation ashes. Unlike traditional cremation that burns at scorching temperatures above 1500°F, water cremation preserves these minerals more completely and naturally.
Here's something important for both families and funeral directors to know: water cremation ashes yield about 32% more volume than flame cremation. This practical difference means families will need slightly larger urns or containers for their loved one's remains.
The liquid that remains after the process is completely sterile and contains no DNA or tissue. This pH-neutral solution actually benefits wastewater treatment facilities due to its nutrient content – another way this process gives back to the earth.
The Water Cremation Ashes Process
At American Mortuary Coolers, we help funeral homes across the country implement this gentle process. Here's how water cremation ashes come to be:
The journey begins with placing the body in a specially designed stainless steel vessel – think of it as a dignified cradle for this final transition. Next, we introduce that special mixture of water and alkali. Depending on the system, the vessel is then heated to either a lower temperature (around 200°F) for 14-16 hours, or a higher temperature (around 300°F) under pressure for just 4-6 hours.
Throughout this time, the solution gently circulates, working with nature to accelerate the decomposition process. When the cycle completes, only bone minerals and any metal implants remain. The bone minerals are carefully dried and processed into a fine powder using a cremulator, similar to what happens after flame cremation. Finally, these water cremation ashes are collected and placed in an urn or container for the family.
Every step of this journey is handled with dignity, care, and respect by trained professionals. Modern alkaline hydrolysis chambers include sophisticated safety features and are designed with both efficiency and minimal environmental impact in mind.
Composition & Appearance of Water Cremation Ashes
When families receive water cremation ashes, they often notice several distinct differences from traditional cremation remains:
The color is remarkably brighter and whiter than flame cremation ashes, which tend to appear gray or dark due to carbon content. The texture feels finer and more powdery, with a consistent quality throughout – the particles are typically smaller and more uniform.
These ashes are primarily composed of calcium phosphate (the natural mineral component of our bones) and are free from the carbon residue found in flame cremation remains. As mentioned earlier, there's about 32% more volume, which simply means a bit more of your loved one to keep or scatter.
Many families appreciate the purity of water cremation ashes – they're free from contaminants like carbon, smoke particles, or other byproducts of combustion. They're also rich in calcium and phosphorus, making them particularly wonderful for memorial plantings or living urns.
We've heard many touching comments from families about the clean, pure appearance of these remains. Some find this aesthetic difference meaningful, especially when displaying an urn or incorporating ashes into memorial jewelry or art pieces. There's something comforting about the bright, natural quality that reflects the gentleness of the process itself.
Water Cremation vs. Flame Cremation: Safety, Volume & Environment
When families ask us about the differences between water and flame cremation, I often find myself reaching for a simple comparison: one uses gentle water, the other intense fire – and that fundamental difference affects everything from the ashes themselves to their impact on our planet.
At American Mortuary Coolers, we've helped funeral homes across the country transition to offering water cremation. The differences we see between water cremation ashes and traditional remains go far beyond just appearance.
Environmental Impact Comparison
The environmental benefits of water cremation are truly remarkable. While a traditional cremation releases about 500 pounds of carbon dioxide – equivalent to driving over 600 miles – water cremation produces virtually no direct emissions. That's a breath of fresh air, literally!
Water cremation uses about 90% less energy than flame cremation, a significant reduction in resource consumption. Yes, the process does use approximately 400 gallons of water – about what a family of four uses daily – but this water doesn't go to waste. Once the process is complete, the resulting sterile effluent can benefit wastewater treatment or even serve as nutrient-rich fertilizer where regulations permit.
One of the most striking environmental advantages comes from how water cremation handles mercury from dental fillings. Traditional cremation releases this mercury into the atmosphere, contributing to air pollution. Water cremation, on the other hand, safely captures and removes mercury, preventing its release entirely.
| Factor | Water Cremation | Flame Cremation |
|---|---|---|
| Energy Use | Uses approximately 90% less energy | Requires significant fossil fuel consumption |
| Carbon Emissions | Virtually zero direct emissions | Emits over 500 pounds of CO2 per cremation |
| Mercury Emissions | None | Releases mercury from dental amalgams |
| Water Usage | About 400 gallons per process | Minimal water usage |
| Chemical Use | Alkali solution (5% of total volume) | None, but produces various combustion byproducts |
| Resource Recovery | Metals can be recovered intact and recycled | Metals are partially melted and degraded |
According to National Geographic's report on cremation emissions, these environmental considerations are becoming increasingly important to families making end-of-life decisions.
Safety Considerations
Water cremation ashes offer several safety advantages that many families find comforting. The fine powder is more stable and less likely to cause respiratory irritation than the dustier particles from flame cremation. There's also peace of mind knowing that water cremation ashes contain no combustion byproducts like dioxins or furans.
For funeral directors, water cremation simplifies the preparation process. Unlike flame cremation, there's no need to remove pacemakers or other medical devices that might explode under intense heat. This reduces handling risks and preserves these devices for potential recycling – a small but meaningful environmental benefit.
I've had funeral directors tell me how much they appreciate not having to worry about these safety concerns anymore. One director in Colorado mentioned, "It's one less thing to worry about, and one more way we can assure families their loved one is being treated with the utmost care."
Volume and Handling Differences
When families first receive water cremation ashes, they're often surprised by the volume – about 32% more than flame cremation produces. This increased amount creates both practical considerations and meaningful opportunities.
The practical side means families need larger urns or multiple containers. We often recommend funeral homes prepare families for this difference in advance, perhaps by displaying sample containers showing the volume comparison.
But there's a beautiful upside to having more remains – more possibilities for memorialization. With additional ashes available, families can more easily:
Share remains among multiple family members without feeling like anyone receives "too little"
Create multiple memorial items such as jewelry, glass art, or plantings
Set aside portions for different purposes – perhaps some for display at home and some for scattering at a meaningful location
The bright white, fine texture of water cremation ashes also lends itself beautifully to memorial art projects. Many glass artists and jewelry makers comment that the purer composition creates more vibrant results in their creations.
For families concerned about their environmental legacy, the choice between water and flame cremation often becomes clear when they understand these differences. As one of our funeral home partners put it, "When people realize they can have a final act that's gentler on the earth, many feel it's their last chance to make a positive impact."
From Ashes to Memorial: Handling, Rituals & Environmental Use
After the water cremation process is complete, families have so many meaningful ways to honor their loved ones with water cremation ashes. We've seen how funeral homes across the country help families steer these deeply personal choices.
Urn Selection and Considerations
When it comes to choosing the right container for water cremation ashes, there's one practical detail families should know right away: you'll need more space. Water cremation produces about 32% more remains than flame cremation, which means standard urns might not hold everything.
Many families are choosing biodegradable urns made from recycled paper, salt, or plant fibers that naturally return to the earth when buried. Others prefer companion urns—originally designed for couples but perfect for accommodating the larger volume of water cremation remains. Some families choose to share the memories by dividing the ashes into multiple smaller containers, while others commission artistic vessels that serve as both memorial and home décor.
"We had my mother's ashes placed in a handcrafted ceramic urn that reminds us of her favorite pottery," one daughter told us. "It feels like something she would have chosen herself."
Memorial Options for Water Cremation Ashes
The pure white water cremation ashes open up a world of memorial possibilities. Many families are drawn to living memorials—using special tree urns where ashes nourish a growing sapling, creating memorial gardens enriched by the remains, or even participating in coral reef restoration programs that incorporate ashes into new ocean habitats.
Keepsake items have become increasingly popular, with options ranging from memorial jewelry containing small amounts of ashes to stunning glass art where the remains become part of blown glass creations. Some companies even transform ashes into diamonds or press them into vinyl records containing meaningful music or recorded messages.
Of course, traditional options remain available too. Many families choose cemetery burial in urn plots, placement in columbarium niches, or scattering in places that held special meaning to their loved one (always with proper permissions, of course).
The Unique "Tree Tea" Option
Water cremation offers something no other process can: the liquid effluent—sometimes lovingly called "Tree Tea"—can be used as plant fertilizer. This sterile solution contains nutrients that nourish plants and trees, creating a powerful symbol of life's continuation.
Progressive funeral homes now offer families the option to use this liquid to water memorial plantings. As one widow shared after using Tree Tea to nourish flowers in memory of her husband: "It fulfilled his wish to 'live on' as plants. There's something profoundly comforting about seeing those flowers bloom and knowing they contain his essence."
Ritual and Ceremony Considerations
Families incorporate water cremation ashes into memorial services in many of the same ways as traditional cremation, but with some beautiful differences. Many facilities now offer witnessing options for the water cremation process, which families often find less emotionally challenging than witnessing flame cremation.
Given the water-based nature of the process, some families create ceremonies that incorporate water elements—releasing biodegradable urns into lakes or oceans, or creating flowing water memorials. For religious families, some facilities offer the option to use holy water in the process, creating a meaningful spiritual connection that honors their traditions.
Environmental Applications
For environmentally conscious families—and that's often why they chose water cremation in the first place—water cremation ashes offer several eco-friendly memorial options that complete their loved one's green legacy.
Conservation burials allow ashes to be laid to rest in protected natural areas, supporting land preservation efforts. Innovative companies now create habitat-supporting structures containing ashes, from artificial reefs to bird nesting boxes. When permitted by local regulations, ashes can enrich soil in family gardens, farms, or forestry projects.
As one family member put it: "Dad was a lifelong environmentalist. Using his ashes to help grow new trees in the forest where he used to hike feels like the perfect final chapter to his story."
These options create a consistent approach to end-of-life care that honors both the person who has passed and the planet they cared for. At American Mortuary Coolers, we're proud to support funeral homes as they help families create these meaningful, sustainable memorials with water cremation ashes.
Going Green with Water Cremation: An Eco-Friendly Farewell
Availability, Cost & Legal Guide to Water Cremation Ashes
Here at American Mortuary Coolers, we talk with funeral homes across the country every day – from our home base in Johnson City, Tennessee to funeral directors in New York, Chicago, Dallas, and Los Angeles. One thing we've noticed? The growing interest in water cremation is often met with the practical question: "But is it even available where I live?"
Legal Status Across the United States
The legal landscape for water cremation is evolving quickly. As of 2024, about 26 states have given the green light to this gentle alternative, with more considering legislation each year.
Good news if you're in California, Colorado, Florida, Georgia, Idaho, Illinois, Kansas, Maine, Maryland, Minnesota, Missouri, Nevada, New Hampshire, New York, North Carolina, Oregon, Utah, Vermont, Washington, or Wyoming – water cremation is legally available in these states.
That said, even where it's legal, you might need to call around. Not every funeral home has invested in the specialized equipment yet, though we're seeing that change as more families ask about greener options.
"When we installed our first aquamation system in Minnesota," one funeral director told me, "we expected some interest. What we didn't expect was families driving from three states away because they were so committed to this option."
Finding Water Cremation Services
If you're helping families interested in water cremation ashes, here's how to connect them with services:
Start with a simple online search for "water cremation" or "aquamation" in your area. Many providers now proudly advertise this option on their websites. Don't hesitate to call local funeral homes directly – even if they don't offer it themselves, they might partner with a facility that does.
The Cremation Association of North America (CANA) maintains a helpful member directory that can point you toward facilities offering alkaline hydrolysis. Their position paper on alkaline hydrolysis also provides valuable insights for funeral professionals.
For families in states where it's not yet available, don't lose hope. Many funeral homes can arrange transport to neighboring states – something we're seeing more frequently as demand grows.
Cost Considerations
When families ask about price, water cremation ashes services typically range from $2,000 to $4,000, putting them in the same ballpark as traditional flame cremation, though sometimes slightly higher.
What affects the cost? Location matters a lot – prices in urban centers like Los Angeles or New York tend to be higher than in smaller communities. The package chosen makes a difference too – a simple direct cremation versus a full-service option with viewing and ceremony.
If transport to another state is needed, that will add to the cost. And of course, the urn selection can range from simple containers to beautiful handcrafted pieces designed to hold the larger volume of water cremation ashes.
Many providers understand this is a difficult time financially for families and offer payment plans or pre-planning options. We've even seen some innovative funeral homes create subscription models for pre-planning that make this option more accessible.
Cultural and Religious Considerations
The conversation around water cremation continues to evolve in religious communities. Some Catholic dioceses have expressed concerns, particularly about the liquid effluent, while others have found the process acceptable. It's a mixed picture that continues to develop.
Jewish perspectives vary widely, with some rabbinical authorities embracing it as an alternative to burial while others prefer traditional practices. Interestingly, some Native Hawaiian communities have found water cremation aligns beautifully with their traditional bone-cleaning practices.
Most Protestant denominations, along with Buddhist and Hindu traditions, have generally accepted water cremation alongside flame cremation. The respectful, gentle nature of the process resonates with many spiritual perspectives on death and change.
For families with religious questions, a conversation with their spiritual leader is always the best starting point. The landscape is changing rapidly as more religious authorities learn about the process and its benefits.
Equipment and Facility Requirements
For our funeral home partners considering adding water cremation, we're transparent about what's involved. The specialized alkaline hydrolysis equipment represents a significant investment – typically between $150,000 and $400,000 depending on the system's size and features.
Beyond the equipment itself, funeral homes should plan for potential facility modifications. These might include plumbing upgrades, electrical work, or structural changes to accommodate the vessel. Staff will need training not just on operating the equipment but also on the unique properties of water cremation ashes and how they differ from flame cremation remains.
The regulatory requirements vary widely by location – something our team at American Mortuary Coolers helps funeral homes steer across our service regions. We've guided many funeral directors through the process of adding this option to their services, from equipment selection to installation to staff training.
As one funeral director in Oregon told us after installing their system: "It was a significant investment, but the response from families has been overwhelming. They're grateful for a choice that aligns with how their loved ones lived – with care for the earth."
