Aquamation (also called water cremation, alkaline hydrolysis, or bio-cremation) is an eco-friendly alternative to traditional flame cremation. It uses water, gentle heat, and alkaline solution to naturally decompose the body, leaving only clean bone ash. The process produces 20% more ashes than flame cremation and has a much smaller carbon footprint.
The average cost of pet aquamation is $150 to $400, with an average of $250 — about 20–30% more than traditional flame cremation.

| Medium dog | 25–50 lbs | $89–$129 | $219–$289 |
| Large dog | 50–80 lbs | $99–$149 | $249–$329 |

Aquamation vs. Flame Cremation
| Feature | Aquamation | Flame Cremation |
|---|---|---|
| Process | Water + alkaline solution + gentle heat | Fire (1,400–1,800°F) |
| Temperature | 200–350°F (low energy) | 1,400–1,800°F (high energy) |
| Duration | 6–8 hours (pets) or 18–20 hours | 1–3 hours |
| Carbon footprint | ~90% less CO₂ than flame | High — significant emissions |
| Ashes returned | ~20% more ashes, fine sand texture | Standard amount, coarse texture |
| Ash color | White to light tan | Gray to dark |
| Cost (private) | $150–$400 | $100–$400 |
| Eco-impact | Very low — no mercury, no emissions | Moderate — CO₂, mercury from fillings |
| Availability | Growing but limited | Widely available everywhere |
How Aquamation Works
The process is gentle and natural:
- Body placed in chamber: Your pet is placed in a stainless steel chamber filled with water and an alkaline solution (potassium hydroxide).
- Gentle process: The chamber is heated to 200–350°F and gently agitated for 6–20 hours.
- Natural decomposition: The alkaline solution breaks down organic tissue into amino acids, peptides, sugars, and salts — all natural compounds.
- Bone collection: Only clean bone remains — processed into fine, white-to-tan ash.
- Ashes returned: You receive about 20% more ashes than flame cremation, with a softer, sand-like texture.
- Water treatment: The remaining solution (effluent) is sterile and treated — safely returned to the water cycle.
Frequently Asked Questions
How much does pet aquamation cost?
Pet aquamation costs $150 to $400, with an average of $250. Private aquamation for a cat or small dog costs $189–$249. For a large dog, it costs $249–$329. Communal aquamation (no ashes returned) costs $79–$200. It's about 20–30% more expensive than flame cremation but much more eco-friendly.
Is aquamation available in my area?
Aquamation is available in many U.S. states but not everywhere. Search "pet aquamation near me" or "water cremation pets [your city]." States with the most providers include California, Florida, Texas, New York, and Minnesota. Availability is growing rapidly — check with your vet or local crematory.
Why is aquamation better for the environment?
Aquamation uses about 90% less energy than flame cremation and produces no direct emissions. It releases no CO₂, mercury, or particulate matter. The process uses water and alkaline solution, and the remaining liquid is sterile and safe. It's the most eco-friendly aftercare option available.
Are aquamation ashes different from flame cremation ashes?
Yes. Aquamation produces about 20% more ashes with a finer, sand-like texture and a white to light tan color. Flame cremation ashes are coarser and gray-to-dark colored. Both are safe to keep in an urn, scatter, or bury. Many owners find aquamation ashes more pleasant to handle.
