Aquamation in Hawai‘i: A Gentle, Green Alternative to Cremation

What Is Aquamation?

Aquamation, scientifically termed alkaline hydrolysis, is a flame-free method of body disposition that uses water, gentle heat, and an alkali solution (usually potassium or sodium hydroxide) to accelerate the natural breakdown of tissues into bone fragments and nutrient-rich liquid. (Interra Green Burial)

Often described as a “gentle whirlpool bath,” this process returns about 20% more remains than flame cremation—and much smoother, flour-like in texture. The liquid byproduct is sterile and safely returned to wastewater treatment systems, with no toxic emissions, making it a more environmentally friendly option (https://www.hawaiinewsnow.com, Interra Green Burial, Aquamation Info, US Funerals).

Legal Status & Availability in Hawai‘i

In July 2022, Hawai‘i officially legalized aquamation by adding “water cremation” to its legal definition of cremation (Aloha Mortuary New). Though it’s now approved, few facilities currently offer it, largely due to the high cost of equipment and limited public exposure (Nolo).

Why It Matters Here

1. Cultural Alignment Aquamation respects Native Hawaiian burial traditions, which historically involved removing and caring for the bones (iwi) with reverence. Unlike traditional cremation, aquamation produces clean bones that can be honored according to these ancestral practices (Aloha Mortuary New).

   
   

2. Environmental Responsibility Hawai‘i has a deeply rooted connection to land and ʻāina. Unlike flame cremation, aquamation emits no harmful greenhouse gases, eliminates the need for embalming chemicals, and uses much less energy—aligning with regenerative values (Aquamation Info).

Final Thoughts

Aquamation is more than an alternative—it’s an option woven with cultural sensitivity and environmental mindfulness. While still new to our islands, it's gaining traction and may soon become a meaningful choice for those seeking respectful, eco-conscious care at the end of life.
