Natural Burial and Newer Authorized Methods
Methods beyond burial and flame cremation exist only where a legislature has defined and licensed them. The definitions are short, the licensing is specific to the facility as well as the process, and what comes back to the family differs in each case.
The rule in short
State law authorizes disposition methods by name. Conventional burial and cremation are available everywhere; alkaline hydrolysis and natural organic reduction exist only where a statute defines the process and licenses the facility. Natural burial is not a separate legal method but a set of cemetery rules on chemicals, containers and vaults. What each produces differs, and the destination rules that follow depend on how the statute classifies the output.
Disposition methods are creatures of statute. A funeral establishment cannot offer a process simply because it works or because a neighboring state permits it; the legislature has to name the method, define it, and license the facility that performs it. That is why the map of what is available changes at state lines, and why the first question about any newer method is not whether it is safe but whether it is defined.
The two methods available everywhere
Burial and flame cremation are authorized in every state, and the machinery around them is mature. Both run through the same front end: a death certificate filed by the certifying physician or medical examiner, a disposition permit issued by the registrar or local health authority, and authorization from the person the priority statute identifies. Cremation adds the identification, clearance and waiting requirements described in the sequence a crematory must complete.
Everything else in this area is a variation on those two, either a change in what happens to the body or a change in what may be placed in the ground with it. Keeping that framing straight avoids the common confusion between a method, which the legislature authorizes, and a practice, which a cemetery permits.
Natural burial is a rule set, not a method
Natural burial, sometimes called green burial, is conventional burial with restrictions layered on top. The body is not embalmed with formaldehyde-based chemicals, or is not embalmed at all. The container is a shroud or an untreated wooden or wicker casket. No outer burial container or vault is used, so the ground settles naturally, and markers are often flat stones or plantings rather than monuments.
None of that requires a special statute, and none of it is prohibited by one. It requires a cemetery willing to permit it. The two obstacles are practical: many cemeteries require a vault so that the grounds stay level for mowing equipment, and grave depth and access rules are set by the cemetery rather than by law. A family planning a natural burial should confirm in writing that no vault is required before buying an interment right, since the recorded rules bind subsequent holders as explained in what a cemetery plot conveys.
| Method | Legal basis | What it produces | Where availability breaks down |
|---|---|---|---|
| Conventional burial | Authorized in every state | An interment in a cemetery or authorized burial ground | Cemetery rules on containers, vaults and markers |
| Natural burial | Conventional burial under stricter cemetery rules | An interment without vault or chemical preservation | Few cemeteries accept it; sections fill quickly |
| Flame cremation | Authorized in every state, with added procedural gates | Processed bone fragments returned to the family | Waiting periods and coroner clearance can delay it |
| Alkaline hydrolysis | Only where a statute defines it and licenses the facility | Bone fragments, processed like cremated remains, plus a liquid effluent | Not authorized in many states; facilities are sparse |
| Natural organic reduction | Only where a statute defines it and licenses the facility | Soil, returned in quantity to the family or donated | Authorized in a minority of states; transport costs dominate |
Hydrolysis and organic reduction as statutory categories
Where alkaline hydrolysis is authorized, the statute defines it tightly: the reduction of human remains to bone fragments and essential elements in a licensed facility using heat, pressure, water and base chemical agents. The definition matters because it determines what is licensed and what the output is. The bone fragments are processed and returned in the same way cremated remains are, and several statutes place hydrolyzed remains alongside cremated remains for the purposes of scattering and placement.
Natural organic reduction is defined even more briefly in the states that recognize it, as the contained, accelerated conversion of human remains to soil. The output is soil rather than fragments, and it is returned in a volume most families do not anticipate, which is why statutes and providers address donation to a conservation project as an alternative to taking delivery. Both processes are licensed by facility as well as by method, so a state may authorize the process and still have no place to perform it.
The destination rules follow the classification, not the technology. Where a statute treats hydrolyzed remains as equivalent to cremated remains, the scattering and placement rules for ashes apply directly. Where a newer method's output has no statutory classification, a cemetery, a park agency or a scattering permit office has no category to place it in, and the answer is frequently a refusal for want of a rule rather than a considered objection. That question is worth asking before the method is chosen.
What does not change with the method
Whichever process is chosen, the body reaches it through the same chain of custody. A licensed establishment takes the body into its care, files the certificate with the registrar, obtains the permit, and delivers the body to the facility that performs the process. A family cannot contract directly with a hydrolysis or reduction facility in most states any more than it can with a crematory, because the statute puts a licensed intermediary in the path. Prices for the process therefore appear on the establishment's price list rather than on the facility's.
Three obligations travel with every method. Authorization must come from the person entitled to control disposition, identified by the ranking in the statutory priority list or by a written appointment. The death must be registered and a disposition permit obtained before anything final happens. And the facility must be able to show which remains are whose, through a tracking system that the regulator can inspect.
The federal pricing rule also applies regardless of method. A provider offering hydrolysis or organic reduction must list it on the general price list, must answer price questions about it by telephone, and may not condition it on unnecessary purchases. Embalming is not required for any of these methods, and a provider may not embalm for a fee without express prior approval outside the narrow circumstances the rule allows.
Choosing a method the home state has not authorized
Transporting a body to a state that authorizes the method is lawful and reasonably common. The transfer runs on the ordinary permit system: a disposition or transit permit from the state where the death occurred, acceptance under the receiving state's rules, and a return of the remains afterward. The obstacle is cost rather than law, and the question to put to a provider is whether it already has a working relationship with a facility across the line.
Whatever comes back then re-enters the ordinary rules about placement. Fragments, processed remains and soil each have to go somewhere, and the permission required depends on the destination rather than on the process that produced them, which is the analysis set out in where cremated remains may lawfully go. Families planning in advance should record the chosen method and the intended destination in the same document, because a method authorized in one state and a destination governed by another are two decisions, not one.
Points to carry away
- A method is available only where the state statute defines it and licenses the facility that performs it.
- Alkaline hydrolysis is defined in statute as a water, heat, pressure and base process leaving bone fragments.
- Natural organic reduction is defined as the contained, accelerated conversion of remains to soil.
- Natural burial is a cemetery rule set rather than a separate statutory method.
- Statutes generally apply the same authorization and identification duties to newer methods as to cremation.
Questions readers ask
Can a family use a method that is legal in a neighboring state?
Usually yes, by transporting the body to a licensed facility in the state that authorizes it. The transfer runs through the ordinary disposition permit system, which requires a permit from the state where the death occurred and acceptance under the receiving state's rules. The remains can then be returned. The cost of transportation is the main obstacle, and the practical question to ask a provider is whether it already has an arrangement with a facility across the line.
Does natural burial require a special cemetery?
It requires a cemetery willing to permit it, which in practice means either a dedicated natural burial ground or a conventional cemetery with a designated section. The obstacles are rules rather than statutes: many cemeteries require an outer burial container so that the ground does not settle, and grave depth and equipment access are set by the cemetery. A family should get written confirmation that no vault is required before buying the interment right.
Is embalming ever legally required?
Very rarely. No state requires embalming as a routine matter, and the federal trade rule forbids a provider from representing otherwise or from embalming for a fee without express prior approval outside narrow circumstances. Requirements appear at the edges: some states require embalming or refrigeration after a set number of hours without other preservation, and some require it for transportation by common carrier or across certain borders. Refrigeration is usually the accepted alternative.

Price Quotes by Telephone and the Disclosures Owed Before a Visit
Under the Funeral Rule a provider must give accurate price information to anyone who asks by telephone, drawn from its price lists or other readily available information. No name or telephone number may be required first, and no appointment may be demanded. Once a discussion of arrangements begins in person, a printed general price list must be handed over, and casket and container lists must arrive before those goods are shown. Price lists must be kept for inspection.
Abandoned Cemeteries and Who Must Maintain Them
Maintenance of a cemetery is funded by an endowment care fund built from a percentage of each sale, with only the income spendable. Where the fund is absent or too small, statutes assign residual duties to townships or counties, often triggered only by a finding of abandonment. Descendants rarely compel maintenance but do hold statutory access rights to graves on private land, enforceable by injunction.
The Casket Handling Rule and Buying Outside the Home
The Funeral Rule forbids a provider from conditioning goods or services on the purchase of a casket from that provider, and from charging any fee for handling a casket bought elsewhere. The general price list must carry a statement telling the buyer that individual items may be selected. A direct cremation may not require a casket, and an alternative container must be offered. Package pricing is permitted, but not if it is used to recover a handling charge the rule prohibits.
