Aftercare, explained

Aquamation vs. flame cremation: an honest comparison

Aquamation — also called aqua cremation or water cremation — is often described as the gentle, eco-friendly choice. We offer both methods here in Tucson, so we want you to have the full picture before you decide.

When you're arranging aftercare for a pet, you may hear about aquamation, also known as aqua cremation, water cremation, or alkaline hydrolysis. We offer it at our facility for families who want it, and we offer traditional flame cremation too. Because we do both, we don't have a reason to push you either way. We just believe you deserve to know how each one works.

What aquamation is

Aquamation isn't only water. The pet is placed in a sealed stainless-steel vessel with water and a strong alkali, typically potassium hydroxide or sodium hydroxide, from the same family of chemicals known as lye. The solution is heated (around 200°F in most pet systems) and circulated, usually for about 20 hours.

During that time, the alkaline solution breaks down the body's soft tissue into a liquid. What remains is the skeleton, which is dried and then processed into the powder returned to the family.

“Water-based” isn't the same as “just water”

Aquamation is often presented as safe and eco-friendly, and when it's done properly it is a controlled, careful process. But we think families should know one thing that rarely comes up: the alkali used is strongly caustic. At these concentrations it can cause serious burns to skin and eyes.

That's why the people who handle it wear protective equipment such as chemical-resistant gloves, eye and face protection, and protective clothing, and why the whole process runs inside a sealed vessel. That isn't a criticism of anyone who offers aquamation; it's simply what the chemistry requires. In our opinion, it's worth knowing that the solution is strong enough to need that level of protection before you decide which method feels right for your pet.

Where the liquid goes

After the process, the remaining liquid (water, the spent alkali, and the broken-down tissue) is typically released into the wastewater system. Some providers collect it for use as fertilizer instead. Most families never ask about this step, so we mention it here.

What aquamation does well

Aquamation has real advantages, and it's the right choice for some families:

  • Lower direct emissions. The machines run on electricity rather than burning fuel.
  • More remains returned. Families typically receive about 20–30% more powder, and it's lighter in color.
  • Comparable cost. Pricing is generally in the same range as flame cremation.

How flame cremation works

Traditional cremation uses heat alone. Your pet is placed in a cremation chamber where high temperatures reduce the body to bone fragments over a few hours. There's no chemical solution and nothing to drain off. The remains are cooled, carefully processed, and returned to you, usually in a signature urn.

Because it takes hours rather than a day or more, flame cremation also makes witness cremation possible, so you can be present, along with same-day return.

What we recommend, and why we offer both

For most families, our recommendation is traditional flame cremation. It's simple and proven, it uses no chemicals, and it allows you to be present and bring your companion home the same day. It's what we've always done and what most families choose.

We also know some families feel strongly about aquamation, and that's a valid choice. So we now offer it here at our Tucson facility, handled by the same local family with the same care. Whichever you choose, your pet stays close to home.
