Choosing aftercare for your beloved companion is a deeply personal decision. Two common options are aquamation and cremation, each with its own process, cost, and environmental impact. Understanding the differences between aquamation vs cremation can help you make an informed choice that honors your pet's memory.
The short answer: Aquamation is a water-based alternative to flame cremation, often considered gentler and more eco-friendly. It typically costs 10–30% more than cremation. Pet aquamation is available in most U.S. states, but providers are still far fewer than flame crematories, so availability may be a factor in your decision.
Aquamation vs cremation: Comparison at a glance
Here's a quick comparison to help you understand the key differences:
| Factor | Flame Cremation | Aquamation (Alkaline Hydrolysis) |
|---|---|---|
| Process | High-heat incineration | Water-based alkaline solution |
| Cost | Typically less expensive | Typically 10-30% more expensive than private cremation |
| Environmental Impact | Higher greenhouse gas emissions, higher energy use | Lower emissions, lower energy use, less carbon footprint |
| Availability | Widely available | Available in most states; far fewer providers |
| What You Get Back | Cremated remains (ashes) | Remains consist of bone minerals, similar to cremation ashes |
How does flame cremation work?
Flame cremation uses intense heat to reduce your pet's remains to bone fragments. These fragments are then pulverized into what most people know as "ashes". The process typically takes 1-3 hours, depending on the size of your pet.
You can choose between private cremation (where your pet is cremated alone) or communal cremation (where multiple pets are cremated together). With private cremation, you receive only your pet's remains. To find local providers, use our directory.
How does aquamation (alkaline hydrolysis) work?
Aquamation, also known as alkaline hydrolysis or water cremation, is a gentler process. It uses water and alkali to break down organic matter.
The body is placed in a stainless steel vessel and submerged in a solution of 95% water and 5% alkali. The solution is gently heated and circulated for several hours, leaving behind only the bones. These are then processed into a powder similar in appearance to cremated remains.

How much does aquamation vs cremation cost?
The cost of both aquamation and cremation varies. Prices depend on your location, the size of your pet, and the type of service you choose (private vs. communal). Here's a breakdown of typical costs based on data from FindPetCremations.com:
- Private Cremation (National Average): \$326 (range: \$283–\$368)
- Communal Cremation (National Average): \$217 (range: \$204–\$230)
- Aquamation: Median \$215 (range: \$80–\$4,995). Note: this is based on a smaller pricing sample.
Private cremation costs by pet size:
- Small pet: mean \$338, median \$325
- Medium dog: mean \$378, median \$379
- Large dog: mean \$416, median \$425
- Giant dog: mean \$469, median \$560
Communal cremation costs by pet size:
- Small pet: mean \$222, median \$250
- Large pet: mean \$260, median \$300
As a general rule, aquamation typically costs 10-30% more than private flame cremation. To see more details, explore our guides on pet aquamation cost and pet cremation cost. Remember that prices can vary significantly by state. For example, private cremation in West Virginia averages around $102, while in Michigan, it averages $572.
What is the environmental impact of aquamation vs cremation?
Aquamation is often touted as a more environmentally friendly option than flame cremation. It uses significantly less energy and produces fewer greenhouse gas emissions.
A study by the University of Minnesota found that aquamation uses about one-eighth the energy of flame cremation. It also reduces greenhouse gas emissions by about 90%. While aquamation does use water, the wastewater is sterile and can be safely discharged into the sewer system.
Where is aquamation legal?
The "legal in roughly half of states" maps you may have seen refer to human aquamation, which is approved state by state under funeral law. Pet aquamation is regulated separately as animal aftercare, and providers operate legally in most U.S. states today; the practical limit is how many providers serve your area, not the law. We cover the confusion in more depth in what is pet aquamation, and our state regulations pages explain how pet aftercare is overseen where you live.
