Water cremation and human composting: what they mean for funeral home value

Families now ask about water cremation and human composting often enough that owners wonder whether they should offer one, and sellers wonder whether a buyer will care. The legal map is changing quickly and the demand is small, so the answer depends on facts you can check. This guide covers the legal status as of late 2026, the adoption data, the cost questions, and how buyers treat these services. Flame cremation trends are a separate subject, covered in rising cremation rates and funeral home values. For the wider market, see the market hub.

Where are alkaline hydrolysis and human composting legal?

Alkaline hydrolysis is authorized in about half the states, and natural organic reduction in about 14. Both maps keep moving, so treat any list as dated and confirm with your state regulator.

NFDA’s alkaline hydrolysis list names Alabama, Arizona, California, Colorado, Connecticut, Florida, Georgia, Hawaii, Idaho, Illinois, Kansas, Maine, Maryland, Minnesota, Missouri, Nevada, North Carolina, Oklahoma, Oregon, South Carolina, Tennessee, Utah, Vermont, Washington, West Virginia, and Wyoming, each with a statute or rule citation. We did not find a more recent authoritative count; check for changes since that date.

NFDA’s human composting page lists Arizona, California (effective 2027), Colorado, Delaware, Georgia, Maine, Maryland, Minnesota, Nevada, New York, Oregon, Vermont, and Washington, with Washington first in 2020. New Jersey became the 14th state in September 2025, with facilities expected within about ten months.

Momentum is not one-way. In May 2026, Funeral Director Daily reported that a bill passed New Hampshire’s House but failed in its Senate, and that Oklahoma’s governor vetoed a bill both chambers had passed. Licensing is also catching up: Colorado’s SB 24-173 makes “natural reductionist” a licensed role starting Jan. 1, 2027. Our guide to tougher state funeral regulation follows that broader trend.

How many families choose them?

Very few so far. CANA estimates both methods combined at about 0.3% of deaths in states where they are practiced and 0.1% nationally.

That figure comes from CANA’s 2025 statistics report, which also found “no indication” that the new methods had affected cremation growth. CANA notes they are often legalized as a form of cremation and counted inside cremation statistics, which is why the national cremation rate does not show them separately.

Translate that into one firm’s numbers. At 0.3% of deaths, a funeral home serving 300 families a year would expect roughly one alternative-disposition request a year if its families behaved like the state average. Interest may run higher where the methods have been legal longest, and a firm that markets the option will draw more than its share. Still, the arithmetic explains why most firms that offer these services either refer families to a specialist or serve other funeral homes on a trade basis.

What does it cost to add water cremation or human composting?

More than the equipment price. Owners should budget for the unit, building work, utilities, permits, staff training, and the time it takes to reach a volume that covers fixed costs.

We have not found a neutral published survey of equipment or installation costs, so get written vendor quotes. The questions that drive the total:

• Space and structure. Composting vessels need room for weeks-long cycles; hydrolysis units need floor loading and utility access.
• Utilities and discharge. Ask your local utility what it requires before it will accept hydrolysis effluent, and in writing.
• Licensing. Some states license the process, the facility, or the operator separately, as Colorado will from 2027.
• Volume source. Your own families, other funeral homes, or a regional referral network.

Can a funeral home offer it without owning equipment?

Yes, and in our experience that is the more common arrangement. A firm can arrange the service through a licensed provider in its own state or, where the method is not yet legal locally, through a facility in a state that allows it, as the New Jersey family in the 6abc report did with a Washington provider. The funeral home handles the arrangement, transport, and paperwork and lists the charge on its price list. Margins are thinner than doing the work in-house, but there is no capital at risk, and a buyer will see a referral relationship rather than equipment to inspect.

The same discipline applies to flame cremation; compare this math with our guide to adding cremation capacity before a sale, where volume is usually easier to prove.

Does offering either change what a buyer will pay?

In our experience, rarely by itself. Buyers pay for earnings they can verify, and alternative dispositions are too small at most firms to change earnings. The exceptions are firms that run a documented trade or regional business with it.

Where the line does matter, buyers look at four things:

1. Revenue and margin by case, separated from the rest of the business for at least two years.
2. Where the cases come from: referral relationships that would survive the sale, or the owner’s personal network.
3. Permits and licenses, and whether they transfer to a new owner or must be reissued.
4. Equipment condition and maintenance records, since a lightly used unit still costs money to keep running.

A buyer may also see strategic value that does not show in earnings yet: a first-mover position in a newly legal state, or a service that keeps environmentally minded families from going elsewhere. That can help in a competitive process, but expect buyers to treat it as a reason to choose your firm rather than a line they add to the price. We have no data showing a premium multiple for offering either service.

How should a seller present an alternative-disposition line?

As its own small business with its own numbers. Mixing it into cremation revenue hides the information a buyer needs and invites skepticism.

If you also run a retort, the buyer will review it with the crematory rules covered in buying a crematory. In The Four-Number Funeral Home Valuation Screen, alternative-disposition cases belong in the disposition mix, but at today’s volumes they rarely move the average revenue per call enough to change a firm’s place in a range.

What could change by 2030?

More states will likely authorize human composting, and California’s law takes effect in 2027, which adds the largest state in the country to the map. Adoption could rise as facilities open closer to families.

None of that changes the core test. An owner considering either service should ask whether it will produce enough documented cases to pay for itself within a few years. A seller should present what exists, with records, and not ask a buyer to pay for a trend. We will update this page as legal status changes.
