Aquamation: How It Works and Its Environmental Impact

The process, the science, and why it significantly reduces environmental impact compared to traditional cremation.

Aquamation, also known as alkaline hydrolysis or water cremation, is one of the newer aftercare options available to pet owners – and one of the most misunderstood. The name alone raises questions for a lot of families: what does it actually involve, is it really as different from cremation as it sounds, and does it still give you the same outcome – your pet’s ashes, returned to you? Here’s what actually happens, and why it matters both practically and environmentally.

A Brief History of Aquamation

Alkaline hydrolysis is not a brand-new invention. The underlying chemical process has been used for decades in research and medical settings, and it has been used for human and animal aftercare in various forms since the early 2000s, gaining wider adoption over the past decade as more states have clarified its legal status and more families have asked for eco-conscious options. It’s sometimes marketed under different names – aquamation, water cremation, bio-cremation, or resomation – but the underlying process is fundamentally the same.

How the Pet Aquamation Process Works

Instead of flame, aquamation uses a combination of water, heat, and a small amount of alkali to accelerate the same natural breakdown that occurs during decomposition, just condensed into a period of hours rather than months or years. Your pet is placed in an individual, sealed vessel, where the solution – roughly 95% water and 5% alkali – circulates at a controlled temperature for a number of hours. What remains afterward is bone mineral, which is processed into ashes and returned to you, just as with flame cremation.

The main practical difference is time: aquamation typically takes considerably longer than flame cremation, since it relies on chemistry and water flow rather than high heat. Where flame cremation might take a few hours, aquamation is closer to a full day. For most families, this simply means slightly longer to wait for your pet’s ashes to be ready – the outcome, in terms of what you eventually receive, is functionally very similar.

What the Ashes Look Like

One common question is whether aquamation ashes look different from those produced by flame cremation. The answer is: slightly, but not in a way most families notice or mind. Aquamation ashes tend to be a bit lighter in color and finer in texture, since the process is gentler on bone mineral than high heat. Functionally, they can be placed in an urn, scattered, or kept as a keepsake in exactly the same way as ashes from flame-based cremation.

Aquamation vs. Cremation: The Environmental Impact

Aquamation uses substantially less energy than flame-based cremation – independent sources studying the process commonly cite reductions in the range of 90% or more – and it does not rely on burning fossil fuels or release the airborne emissions associated with combustion. For families thinking about their environmental footprint even in small, personal decisions, this can make a meaningful difference without requiring any compromise on the outcome that matters most.

“It uses only five percent of the energy of cremation and creates 10 percent of the carbon footprint. In addition, it produces zero methane gas, unlike burials.”

Lap of Love

For families who want to make an environmentally conscious choice during an already difficult decision, aquamation offers a meaningful way to reduce that impact without changing what matters most: your pet’s ashes are still returned to you, in the same way, to be kept, scattered, or memorialized however feels right to you.

Common Misconceptions About Aquamation

Because aquamation is less familiar than traditional cremation, a few misconceptions tend to come up. One is the assumption that it’s somehow less respectful or less “complete” than flame cremation – in reality, it’s simply a different mechanism for achieving the same result, and many families who choose it describe feeling more, not less, at peace with their decision, precisely because of its gentler environmental footprint.

Another common question is whether aquamation is available for pets of all sizes. In most cases, it is, though very large pets may need to be accommodated at a specific facility equipped for their size – our team can help confirm availability based on your pet’s size and your location.

Is Aquamation Right for Your Family?

• You want an eco-friendly pet cremation option instead of flame-based cremation.
• You still want your pet’s ashes returned to you afterward.
• You’re comfortable with a somewhat longer processing time in exchange for a smaller environmental footprint.
• You understand that witness appointments are not available for this specific process.

As with every option we offer, there’s no wrong choice here – only the one that best matches what matters to your family. If you’re drawn to Aquamation but still have questions about logistics, cost, or availability at your nearest location, we’d rather you ask than guess.

How Aquamation Compares to Flame Cremation, Side by Side

Families weighing Aquamation against traditional flame cremation often find it helpful to think through a few key factors side by side, rather than treating it as a single all-or-nothing choice. In terms of outcome, both processes return your pet’s ashes to you, and both allow those ashes to be placed in an urn, scattered, or kept as part of a memorial keepsake – so the end result, in terms of what you’re left with, is very similar.

Where they differ most is in the process itself: flame cremation uses high heat over a shorter period, while Aquamation uses water and gentle chemistry over a longer period. Flame cremation supports Witness Cremation, allowing you to be present as your pet is placed into the chamber, while Aquamation does not currently offer that option at our facilities. And environmentally, Aquamation offers a meaningfully smaller footprint, without any airborne emissions.

How Aquamation Fits Into Broader Environmental Choices

For many families, choosing Aquamation is part of a broader set of values that show up in other areas of life as well – how they think about energy use, waste, or their footprint on the planet more generally. There’s no need to have a fully developed environmental philosophy to choose this option; plenty of families simply appreciate having a lower-impact choice available to them at a moment when they’re already thinking carefully about how to honor their pet well. Whatever your reasons, Aquamation is offered with the same level of individualized care as every other service we provide.

Questions Families Often Ask About Aquamation

Because Aquamation is newer to many pet owners than traditional cremation, we find that families often arrive with similar sets of questions. One of the most common is whether the process is somehow less thorough or complete than flame cremation – it isn’t; it’s simply a different mechanism that achieves a comparable result through water and chemistry rather than heat. Another common question is about odor or mess during the process itself – Aquamation takes place in a fully sealed, contained system, with nothing visible or noticeable to families waiting on an update.

Some families also ask whether choosing Aquamation means giving up a more “traditional” send-off. We’d gently push back on that framing: what makes any form of aftercare feel meaningful isn’t the specific mechanism used, but the care, respect, and intention behind how your pet is treated throughout, and the way you choose to remember them afterward. Aquamation is held to exactly the same standard of individual, dedicated care as our Pet Cremation and Memorialization Services.
