If you are asking “Is aquamation legal in Wisconsin?”, the short answer is: No, human aquamation is not currently authorized within the state of Wisconsin.
Aquamation scientifically known as alkaline hydrolysis or water cremation is not defined or authorized under Wisconsin state statutes governing crematory operations (Wis. Stat. Chapter 440). Under current state law, human cremation is defined strictly as a thermal process using heat and flame. While legislation to expand cremation definitions has been introduced in past legislative sessions, human water cremation facilities cannot legally operate inside Wisconsin borders at this time.
However, eco-conscious families across Milwaukee, Madison, Green Bay, Kenosha, and Eau Claire seeking gentle, green aftercare still have options. Families can choose pet aftercare providers within the state or coordinate out-of-state human water cremation services in adjacent states where it is fully authorized—most notably Minnesota or Illinois.
This 2026 guide explains Wisconsin’s legal framework, how water cremation works, out-of-state options, and tips for choosing an urn for returned bone ash remains.
Wisconsin Aquamation Laws at a Glance
-
Human Remains Legal Status: Not authorized for human disposition in-state. State statutes limit human cremation to flame-based thermal processing.
-
Pet Remains Legal Status: Legal and accessible through specialized pet aftercare facilities and veterinary practices statewide.
-
Regulatory Authority: Wisconsin Funeral Directors Examining Board (under the Wisconsin Department of Safety and Professional Services).
-
Workarounds for Human Remains: Families committed to green water cremation can work with a local Wisconsin funeral home to handle arrangements and transport to an authorized provider in a neighboring state like Minnesota.
-
Final Returned Remains: Pure, pale white bone powder.
What Is Aquamation (Water Cremation)?
Aquamation also called green cremation, bio-cremation, liquid cremation, or flameless cremation is a gentle, water-based disposition method.
Instead of using direct high heat and flame to reduce human remains, aquamation uses a solution of 95% warm water and 5% alkali (potassium hydroxide or sodium hydroxide). Over a 6- to 12-hour cycle inside a sealed stainless steel vessel, gentle liquid flow and natural alkalinity accelerate the body's natural breakdown process.
At the end of the process, only soft, mineral bone fragments remain. These fragments are dried and processed into a fine white powder that can be safely kept at home, buried, or scattered.
Aquamation vs. Traditional Cremation: Key Differences
| Feature | Aquamation (Water Cremation) | Traditional Flame Cremation |
| Primary Method | 95% Water & 5% Alkali Solution | Direct High Heat / Open Flame |
| Energy Consumption | Uses ~90% less energy | High fossil fuel consumption (natural gas/propane) |
| Emissions | Zero direct greenhouse gas stack emissions | Direct carbon dioxide and thermal emissions |
| Returned Remains | Fine, pale white powder | Coarser, gray bone ash |
| Ash Volume | ~20% to 30% greater returned volume | Standard baseline volume |
How Much Does Aquamation Cost?
Because human aquamation cannot be performed inside Wisconsin, overall expenses depend on whether you are utilizing local pet services or transporting human remains out of state:
-
Pet Aquamation in Wisconsin: $150 – $450 (varies by pet weight and local provider)
-
Out-of-State Human Aquamation: $2,500 – $4,500+ (includes transportation, out-of-state provider fees, and return shipping of ashes)
-
Standard Flame Cremation in Wisconsin: $1,400 – $3,500 (widely available statewide)
Choosing an Urn for Aquamation Remains
Whether receiving returned ashes from an out-of-state aquamation provider or choosing traditional flame cremation locally, selecting the correct urn volume is essential. Because water cremation preserves more mineral bone material than high-heat incineration, the returned remains typically occupy 20% to 30% more space than standard flame cremation ashes.
When shopping for an adult memorial vessel, keep internal capacity top of mind:
-
Adult Full-Sized Urns: For water cremation remains, select urns with a volume capacity of 220 to 250+ cubic inches (rather than standard 200 cu. in.) to ensure all ashes fit comfortably.
-
Keepsake Urns: Small mini urns designed to hold a small portion of ashes, allowing multiple family members to share a token memory.
-
Cremation Jewelry: Keepsake pendants and bracelets engineered with tiny inner chambers to carry a small piece of your loved one near your heart.
-
Water-Soluble & Scattering Urns: Specially designed for natural ash-scattering ceremonies in rivers, lakes, private land, or designated outdoor spaces.
Frequently Asked Questions (FAQ)
Will human aquamation become legal in Wisconsin?
Efforts to legalize alkaline hydrolysis have been introduced in the Wisconsin State Legislature (such as Senate Bill 228) with support from trade groups like the Wisconsin Funeral Directors Association. Future legislative sessions may revisit passing authorization laws.
Can I bring aquamation ashes back to Wisconsin from Minnesota or Illinois?
Yes. Once the process is performed legally in another state, you can bring or ship the returned ashes back to Wisconsin. TSA permits cremated remains on flights in carry-on luggage provided the container passes X-ray inspection (e.g., wood, ceramic, or glass urns).
Can I keep cremated remains at home in Wisconsin?
Yes. Wisconsin law permits families to keep returned ashes at home, place them in a columbarium niche, bury them on private property, or scatter them with landowner permission.
