Green Burial in Hawaii: Natural Options, Rules, and What Is Currently Legal

Hawaii's deep cultural connection to the ʻāina — the land — makes green burial an idea that resonates strongly with many island families. And yet, the practical landscape for eco-friendly disposition in Hawaii is more constrained than many people expect. Land is limited, regulations vary by county, and some disposition methods that are available in mainland states are not yet legal in Hawaii. This overview clarifies what is currently available, what is not, and how families can pursue the most natural option legally accessible to them.

What Green Burial Actually Means

A true natural or green burial aims to return the body to the earth without preservatives, non-biodegradable materials, or energy-intensive processes. The core elements:

• No embalming (or use of natural embalming alternatives)
• No metal casket
• No concrete burial vault
• Shroud, biodegradable container, or direct ground contact
• Shallow burial to allow natural decomposition

The practical benefit of this approach — beyond its environmental values — is cost. A direct green burial, where permitted, is typically significantly less expensive than a conventional burial. No metal casket, no embalming, no vault — those three items alone can eliminate $2,000 to $6,000 from a traditional burial bill.

Embalming: Easy to Decline

The first step in any green burial plan is straightforward: decline embalming. As covered in Hawaii law, embalming is not required by state statute for standard burial or viewing (only for specific rare contagious diseases). Under the FTC Funeral Rule, the funeral provider must give you an itemized General Price List, and embalming must be listed as a separate, optional item. You can simply decline it.

Some funeral homes will push back if you want an open-casket viewing, as they may have internal policies requiring embalming for that service. If natural viewing is important to your family, ask whether the facility accommodates it, or look for funeral homes that specifically offer home funeral or natural burial services.

Vault Requirements in Hawaii

Whether a concrete outer burial container (vault) is required depends on the cemetery's own rules, not state law. Hawaii does not have a statewide law mandating vaults for burial. However, many conventional cemeteries require vaults as part of their own maintenance policies — vaults prevent ground subsidence that makes lawn mowing difficult.

Hybrid cemeteries and natural burial grounds that explicitly accommodate green burial either do not require vaults or have biodegradable container alternatives. If a cemetery claims that vaults are "required by law," ask them to cite the specific statute. They almost certainly cannot, because no such statewide statute exists.

Container Options

For green burial, the main options are:

• Shroud: A simple cloth wrapping, typically linen, wool, or cotton. This is the most traditional and most decomposition-friendly option.
• Biodegradable casket: Willow, bamboo, cardboard, or untreated wood caskets without metal hardware. These are legal for burial in Hawaii.
• No container: Some natural burial grounds permit direct earth burial with no container at all, though this is rare in Hawaii given limited ground availability.

A conventional metal casket is not required by law. If a cemetery or funeral home insists one is required, that is a policy or business practice, not a legal mandate.

Is Human Composting (Natural Organic Reduction) Legal in Hawaii?

No. As of 2026, Natural Organic Reduction (NOR) — also known as human composting — is not authorized in Hawaii. The process converts human remains into nutrient-rich soil over a period of weeks using controlled decomposition in a vessel. Several states (Washington, Colorado, Oregon, and others) have legalized NOR, but Hawaii has not yet enacted enabling legislation.

Families committed to NOR must arrange for the body to be transported out of state to a licensed facility in a legalized jurisdiction. This involves interstate transit permits and airline cargo logistics, adding significant cost and complexity.

What About Alkaline Hydrolysis?

Alkaline hydrolysis (water cremation) was legalized in Hawaii in 2022 via Act 294. While not a burial method in the traditional sense — it returns remains in pulverized bone form rather than whole-body burial in the ground — it is environmentally significantly lighter than flame cremation. No combustion, lower energy consumption, no mercury or dioxin emissions. For families whose green values extend to disposition method but who are not committed to burial specifically, water cremation is a legally available option in Hawaii.

Ash Scattering as a Green Alternative

Scattering cremated remains in the ocean is the most common final disposition in Hawaii for families who want a deeply natural, land-light outcome. The regulatory framework for this is covered separately, but the key points are: ocean scattering must occur at least three nautical miles offshore under EPA rules, EPA notification is required within 30 days, and gatherings of 14 or more people on a single vessel require a free DLNR DOBOR marine event permit obtained at least 14 days in advance.

For land-based scattering on private property (with landowner permission), there are no statewide restrictions. Public land scattering requires checking local county codes.

Practical Steps for Planning a Green Burial in Hawaii

1. Identify whether there are certified natural burial grounds or hybrid cemeteries on your island. The Green Burial Council maintains a directory of certified providers, though availability on neighbor islands is limited.
2. Confirm that the cemetery does not require vaults. Get this in writing.
3. Arrange for a shroud or biodegradable container instead of a conventional casket.
4. Decline embalming. Refrigeration satisfies Hawaii's 30-hour rule.
5. If using a funeral home, request their GPL and identify charges for services you do not want.

For families planning ahead, documenting your preferences in a notarized HRS §531B-5 Written Instrument — specifically designating who has authority to direct your arrangements and what method of disposition you prefer — ensures that your green burial wishes are legally binding, not just a request that family members can override.

The Hawaii Funeral Laws and Consumer Rights Guide covers vault requirements, the full legal framework for home burial, ash scattering regulations, and the disposition authorization hierarchy that determines who has the legal power to follow your wishes after you are gone.
