Aquamation is now legal in Tennessee, and the change took effect on July 1 2026. The state’s General Assembly amended its burial‑and‑cremation statutes to recognize “alkaline hydrolysis” as a permissible method of final disposition, placing Tennessee among the growing number of jurisdictions that allow this eco‑friendly alternative to traditional cremation.
Legislative Background
Prior to 2026, Tennessee’s burial statutes listed only traditional interment, embalming, and flame‑based cremation as authorized methods (Tenn. Code Ann. § 44‑12‑101). The absence of language addressing alkaline hydrolysis left funeral directors without a clear regulatory pathway, effectively barring the practice despite its approval in neighboring states such as Kentucky and Virginia.
What Changed in 2026
In the 2025 legislative session, Senate Bill 322 was passed and signed into law. The amendment added a new subsection to § 44‑12‑101 defining “aquamation” (also called alkaline hydrolysis) and setting minimum standards for equipment, temperature control, and waste disposal. The law also requires the Tennessee Board of Funeral Directors to issue a specific license for facilities performing the procedure. Compliance dates were set for July 1 2026, giving providers a six‑month window to meet the new requirements (Tenn. Code Ann. § 44‑12‑101(b) (2026)).
How Aquamation Works
Aquamation uses a pressurized solution of water and potassium hydroxide, heated to approximately 160 °F (71 °C). The body’s tissues dissolve over 3‑4 hours, leaving only bone fragments, which are then milled into a fine powder. The process reduces carbon emissions by up to 90 % compared to flame cremation and eliminates the release of mercury from dental amalgams (Environmental Protection Agency, “Green Disposal Technologies,” 2025).
Implications for Families and Funeral Homes
For families, aquamation offers a lower‑impact option that can be as affordable as standard cremation. Funeral homes must invest in certified equipment and undergo staff training, but many view the upfront cost as offset by growing consumer demand for sustainable services. The new licensing protocol also ensures that facilities meet health‑and‑safety standards, providing added confidence for consumers (Tennessee Board of Funeral Directors, Licensing Guidelines, 2026).
Key Takeaways
- Aquamation is legal in Tennessee as of July 2026.
- The change resulted from Senate Bill 322, which added a clear statutory definition and regulatory framework.
- The process is environmentally friendly and aligns with a national trend toward greener disposition methods.
- Funeral providers must obtain a specific license and adhere to equipment standards.
- Families now have a third, sustainable choice for final disposition.
Is aquamation the same as traditional cremation?
No. Aquamation is an alkaline hydrolysis process that uses water, chemicals, and low heat, whereas traditional cremation relies on high‑temperature flame. The end result—bone ash—is similar, but the environmental impact and chemical by‑products differ significantly.
Do families need to sign a separate consent form for aquamation?
Yes. Tennessee law requires explicit written consent for any disposition method not covered by standard interment or flame cremation forms. Funeral providers must include a specific aquamation consent clause to comply with § 44‑12‑101(b).
How are the bone fragments disposed of after aquamation?
After the tissue dissolution, the remaining bone fragments are rinsed, dried, and milled into a fine powder. Families may receive the powder in an urn, scatter it, or incorporate it into memorial products, just as with cremated remains.
Are there any religious restrictions on using aquamation in Tennessee?
Tennessee law does not impose religious restrictions on disposition methods. However, individual faith traditions may have their own teachings. Funeral homes typically discuss options with families to respect cultural or religious preferences.
What penalties exist for providers who perform aquamation without a license?
Operating without a valid aquamation license constitutes a violation of § 44‑12‑101(b) and can result in fines up to $2,000 per offense, possible revocation of the funeral director’s primary license, and civil liability for improper handling of human remains.
