If you are asking “Is aquamation legal in Minnesota?”, the short answer is: Yes, human aquamation is legal and actively available in Minnesota.
Aquamation, scientifically known as alkaline hydrolysis or water cremation, was authorized in Minnesota under Minnesota Statutes Chapter 149A. Minnesota holds a significant milestone in eco-friendly aftercare as the first state in the nation to legalize alkaline hydrolysis for human remains.
As eco-conscious families across Minneapolis, St. Paul, Rochester, Duluth, and Bloomington seek gentle, green alternatives to traditional burial and flame cremation, water cremation remains a widely accessible, established choice statewide.
This 2026 guide explains Minnesota’s aquamation laws, environmental benefits, average costs, and key tips for selecting an urn for bone ash remains.

-
Regulatory Body: Minnesota Department of Health (MDH) – Mortuary Science Section.
-
Final Returned Remains: Pure, pale white bone powder.
-
Volume Yield: Yields approximately 20% to 30% more ash volume than traditional flame cremation.
What Is Aquamation (Water Cremation)?
Aquamation also called green cremation, bio-cremation, liquid cremation, or flameless cremation is a gentle, water-based final disposition method.
Instead of using direct high heat and fossil fuels 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 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 in Minnesota?
In Minnesota, aquamation pricing varies depending on regional provider availability and service package selection:
-
Direct Human Aquamation: $2,200 – $3,980 (varies by funeral home and inclusive direct cremation options)
-
Full-Service Aquamation (with Memorial Services): $4,000 – $6,000+
-
Pet Aquamation: $150 – $450 (varies by pet weight)
Direct aquamation is competitively priced alongside traditional flame cremation while offering a significantly smaller carbon footprint.
Choosing an Urn for Aquamation Remains
Because aquamation preserves more 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, keeping internal capacity in mind is crucial:
-
Adult Full-Sized Urns: Look for urns with a volume capacity of 220 to 250+ cubic inches (rather than the standard 200 cu. in.) to comfortably accommodate aquamated ashes.
-
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, or private land.
Frequently Asked Questions (FAQ)
Is aquamation eco-friendly?
Yes. Water cremation produces zero direct stack emissions, uses roughly 10% of the natural gas energy of flame cremation, and returns safe, pathogen-free water to municipal water treatment systems.
Can I keep aquamation ashes at home in Minnesota?
Yes. Minnesota law permits families to bring returned cremated remains home, place them in a columbarium niche, bury them in a cemetery, or scatter them on private property with landowner permission.
What size urn do I need for water cremation ashes?
A standard cremation urn typically holds 200 cubic inches. For aquamation remains, selecting an urn rated for 220+ cubic inches ensures all returned ashes fit comfortably.
