Human composting renewal in Colorado: license, cost, and timeline

Last updated 2026-08-18

Do you need a license for human composting in Colorado?

Yes. Colorado law says you cannot operate a natural organic reduction facility without a license, full stop.

That comes straight from the statute, CRS 12-135-203(1): “A person shall not operate a natural organic reduction facility without a license issued under this part 2.” ^[1]

The license comes from the Director of the Division of Professions and Occupations inside DORA. The application covers facility design, equipment, recordkeeping, and a demonstration that you meet the state’s pathogen-reduction and safety standards. There’s no grandfathering. No provisional permission. If you’re holding human remains for conversion into soil, you hold the license or you’re breaking the law.

The license is good for one year and must be renewed annually. Let it lapse and you stop processing immediately. You can’t finish a batch that’s already sitting in a vessel while you sort out the paperwork.

Colorado built this framework through SB21-006 in 2021, and DORA adopted detailed rules in 4 CCR 746-1 in 2023. ^[2] The rules spell out everything from vessel temperature ranges to how you handle multiple bodies in one container. The licensing requirement covers any person or entity performing natural organic reduction of human remains for compensation. A nonprofit needs the same license. A religious organization needs the same license.

How much does it cost to renew a human composting license in Colorado?

The renewal fee is $1,000 a year. The rule is explicit. 4 CCR 746-1, Rule 4.1, says: “The fee for renewal of a natural organic reduction facility license is one thousand dollars ($1,000).” ^[2]

The initial application fee is $1,500. There’s no reduced fee for nonprofits or small facilities. These fees cover the direct and indirect costs of running the program, and DORA can adjust them by rulemaking.

What you get for that $1,000: a year of legal operation, DORA oversight, and the obligation to comply with every recordkeeping, reporting, and inspection requirement. You don’t get a certificate or a patch. You get a paper license, and you must post it conspicuously at the facility.

The rule text doesn’t spell out a late fee, but you’re supposed to apply 60 days before expiration. Miss the window and you risk a gap in licensure, and the state can tell you to stop. You can’t backdate a renewal. Pay by check or electronic transfer through the DORA online portal. No cash.

How long does the state take to process a renewal?

The rules require you to submit your renewal application at least 60 days before your license expires. ^[2] Rule 3.5(A): “A licensee shall submit a renewal application and the required fee no later than 60 days prior to the expiration date of the license.”

That 60 days is your responsibility, not the state’s clock. Colorado doesn’t publish a guaranteed processing time. In practice, if your paperwork is clean and your facility hasn’t had enforcement actions, DORA often processes renewals within 30 days of submission. That’s not a promise. You might hear nothing for weeks, then get a one-line approval email.

Send everything 90 days out. Keep copies of every page you submit.

If you don’t hear back by two weeks before expiration, call the NOR program administrator. DORA’s phone number and staff contacts are on the NOR program page. ^[3] They can tell you if anything is missing. Don’t wait to find out your renewal stalled because a signature was wrong on page 3.

What are the continuing requirements to keep a Colorado NOR license?

Renewal isn’t just a check and a form. The division expects you to stay in compliance all year and to attest to it when you renew.

Rule 3.5(B) requires you to submit “proof of continued compliance with the requirements of this regulation and the Act” with the renewal application. ^[2] At a minimum, that means:

• Temperature logs showing vessels stayed within the required ranges for the full processing period
• Records that each batch hit the mandated pathogen-reduction time and temperature (Rule 8)
• Documentation of any deviations and the corrective actions you took
• Evidence that you screened all remains for non-compostable implants (pacemakers, certain prosthetics) and removed them
• Records of final soil testing if your local environmental health department requires it

Inspections can happen any time during your license term. The rule lets DORA inspect your facility, review records, and take samples. If you got written up during the year, you’ll need to show the problem is resolved before renewal is approved. A violation doesn’t automatically tank your renewal, but it slows things down. The renewal form itself (on the DORA NOR page) is a plain PDF with checkboxes and an attestation statement.

How much does human composting cost for a family in Colorado?

Families in Colorado pay roughly $4,500 to $5,500 for human composting. Renewal fees are the operator’s cost. The price to a family covers the service itself, and it varies by provider.

The Natural Funeral in Lafayette lists its Natural Organic Reduction service at $4,500 on its website. ^[4] That covers the full conversion from intake to the return of soil, usually about four to six weeks. It does not include transport of the body to the facility (typically a few hundred dollars), a death certificate fee, or an urn or planting event. A small ceremony adds cost.

Other providers charge $5,000 to $5,500. Be a Tree, a Colorado company, sits in that range. The spread often reflects whether the provider includes 24/7 removal, witnessed steps, or hand delivery of the soil. Compare line items. At the low end, a direct NOR without ceremony runs about what a basic cremation costs in the state.

Here’s what nobody talks about enough: the online price usually assumes an uncomplicated body. If a pacemaker gets missed on intake and has to come out mid-process, or the body is over 350 pounds and needs a double-vessel protocol, costs climb. Ask for a written estimate that itemizes every surcharge.

How long does the human composting process take?

The biological process runs 30 to 45 days in Colorado, from vessel loading to finished soil. ^[4]

That’s not a guess. The Natural Funeral states its process “typically takes 30-45 days.” That window covers active decomposition inside a stainless-steel vessel, with controlled airflow, moisture, and rotation, followed by a curing period outside the vessel. Temperatures must stay above 131°F for a set number of hours, a standard drawn from the WSU research behind the Colorado rules. ^[5]

After the vessel phase, the material is screened for non-organic items. The soil then cures for another few weeks to stabilize. That curing can push the total to six to eight weeks before the family receives the soil. But the 30 to 45 days quoted covers the core conversion.

Running multiple bodies in a single vessel (allowed under the rules with tracking) doesn’t really change the batch time. The microbial community handles more material fine, as long as the vessel isn’t packed so tight that airflow suffers. What slows things down is low moisture or a cold building. Colorado winters mean you insulate the processing room and watch it.

What paperwork do I need for a renewal application?

The DORA NOR renewal form asks for four things:

• Facility name, address, and license number
• Contact information for the responsible party
• A signed attestation that the facility remains in compliance with all statutes and regulations
• The $1,000 fee

That’s all the form wants. But have your backup ready. A renewal audit can ask for temperature logs, monthly summary reports, staff training records, proof of liability insurance, and documentation of any equipment or procedure changes since your last license.

If you want the full statute text and the whole regulatory framework in one place instead of flipping between browser tabs, the $199 NOR Facilitator Statute Kit from HumusPath at /start includes the Colorado Natural Organic Reduction Act, the administrative rules, and a checklist built straight from the law. It’s not legal advice. It’s a board-confirmable reference that beats reading PDFs on your phone during an inspection.

Where can I get a copy of the Colorado NOR statute and rules?

Start with the Colorado General Assembly for the statute. SB21-006 (2021) created Part 2 of Article 135 of Title 12. ^[1] The enrolled bill is a 13-page PDF at leg.colorado.gov.

For the regulations, the Secretary of State’s website hosts 4 CCR 746-1 as a rulemaking record. ^[2] Search “4 CCR 746-1” and download the PDF. The same page shows the effective date and any pending amendments.

The DORA NOR program page ^[3] links to both, plus the renewal form, a facilities FAQ, and contact info for the advisory committee. Bookmark it. That’s where you’ll hear about fee changes, new inspection protocols, or enforcement actions before anyone mentions them at a conference.

Can a Colorado NOR facility renewal be denied or revoked?

Yes. The statute gives the director power to deny an initial license or a renewal when the applicant doesn’t meet the requirements. ^[1] Common grounds: failure to keep proper temperature logs, repeated pathogen-reduction failures, operating without a license during a lapse, or false statements on the application.

The rules also let the director suspend or revoke a license for any violation of the Act or the regulations. If your renewal is denied, you stop operations and can’t touch the NOR equipment until you reapply and get approved. There’s no automatic appeal to a court, but you can request a hearing under the state administrative procedure act. That takes time and lawyers.

DORA isn’t out to trap you. If you’ve stayed communicative, fixed problems quickly, and can document the corrections, an outright denial is rare. You might get a conditional renewal with a tighter inspection schedule instead.

Are there any pending changes to Colorado’s NOR rules?

As of mid-2026, no proposed rule changes are open for public comment. The Natural Organic Reduction Advisory Committee meets periodically and can recommend rule updates to the director. ^[3] Past discussions touched vessel material standards, soil testing requirements, and how to handle non-human animal remains that wander into a vessel. None of it has moved to rulemaking.

If you hold a license, you get a direct notice when the division opens a rulemaking. Subscribe to the DORA mailing list for the NOR program. Fee changes require rulemaking, so any increase comes with a public notice and a comment period. Don’t run your business on gossip from industry conferences.

Other states keep revising their NOR laws. California recently changed its renewal interval. Florida added a continuing education hour requirement for facilitators. For a side-by-side look, our guides cover human composting renewal in California, Florida, Georgia, and Hawaii. ^[6][7][8][9]

What happens if I let my Colorado NOR license expire?

The day after expiration, you’re unlicensed. You cannot accept new remains. You cannot keep processing a vessel that’s already running. You must secure the facility, notify DORA in writing, and keep records of any active batches until you either renew or transfer them to a licensed facility.

The rules give you no grace period for processing. Some operators tell themselves “the renewal is in the mail, so it’s fine.” It isn’t. If a state inspector shows up on day zero and finds a vessel running without a current license, that’s a violation, and it makes your next renewal harder.

To reinstate, you typically file a late renewal application with an explanation for the lapse. You may owe a reinstatement fee. 4 CCR 746-1 doesn’t list one explicitly, but DORA can impose it through case-by-case enforcement. Expect any pending soil from an expired-license period to get scrutinized for pathogen compliance before it goes back to families.

How do I stay updated on Colorado NOR regulations?

Three reliable channels.

First, the DORA NOR program page ^[3] posts rulemaking notices, meeting minutes, and license-holder bulletins. Check it monthly.

Second, attend advisory committee meetings. They’re open to the public and often held virtually. The agenda goes up on the DORA site. You can ask questions during the public comment period.

Third, the NOR industry’s trade group, not a state entity, circulates summaries of regulatory changes. Always verify against the primary source. The HumusPath state guide series tracks changes too and links back to the original documents. For a printed statute reference, the $199 NOR Facilitator Statute Kit at /start is a one-time purchase with free updates when the laws change.

How does the Colorado renewal compare to other states?

Colorado’s $1,000 annual license fee sits at the midpoint of states that license NOR facilities. Washington charges $1,200 a year. California charges $800 but requires an electronic system that carries its own monthly fee. Oregon charges $1,000. Colorado’s 60-day advance renewal rule is stricter than most: Washington allows 30 days, California 45. ^[6][7]

Colorado also mandates direct DORA inspection authority, which not every state does. A few states hand that off to county health departments. The recordkeeping load in Colorado is heavier because Rule 8.4 requires per-batch temperature logs kept for three years. Other states accept summaries.

One thing holds true everywhere: every state that legalized natural organic reduction ties the license to the facility, not the individual operator. Move locations and you need a new license. Colorado is no different.

Frequently asked questions

What is natural organic reduction?

Natural organic reduction converts human remains into soil through controlled decomposition. The body is placed in a vessel with wood chips, alfalfa, and straw. Over 30 to 45 days, microbial activity breaks down soft tissue and bone, producing about a cubic yard of nutrient-rich soil. No embalming chemicals, no fossil-fuel cremation. Colorado’s law recognizes NOR as a form of final disposition distinct from burial or cremation.

Is human composting legal everywhere in Colorado, or are there local bans?

State law preempts local bans on NOR as a form of disposition. A municipality cannot prohibit natural organic reduction outright. But zoning and land-use rules still apply. A NOR facility must comply with local zoning for a funeral establishment or similar use. Some counties may require a conditional use permit. Check with your city or county planning department before signing a lease.

Can I transport a body from another state to Colorado for human composting?

Yes, as long as the death occurred in a jurisdiction that allows removal of the body for out-of-state disposition. The Colorado facility needs a disposition permit from the coroner or medical examiner of the county where death occurred, plus a transit permit. On arrival, normal intake and screening procedures apply. Some families from Nebraska, Kansas, and Wyoming choose Colorado providers for green disposition.

What happens to pacemakers, implants, and dental fillings during NOR?

The facility must screen all remains and remove devices that could interfere with the process or contaminate the soil. Pacemakers and certain batteries come out because they can explode or leak. Metal implants like hip joints are typically pulled with magnets or by hand after the vessel cycle and recycled. Dental amalgam fillings may remain; the rules don’t require removal, but mercury containment is a topic of ongoing discussion.

Can I donate the resulting soil to a park or forest in Colorado?

Usually not. Colorado Parks and Wildlife and the U.S. Forest Service restrict accepting soil of human origin on public lands. Most families keep the soil for a private memorial garden, scatter it on private property with permission, or plant a tree on family land. Some conservation cemeteries in the state may accept NOR soil; ask the specific cemetery. Disposition of soil must be documented in the NOR facility’s records.

Does insurance cover human composting in Colorado?

Health insurance doesn’t cover funeral expenses. Life insurance death benefits can pay for any final disposition, including NOR. Some pre-need funeral insurance policies cover the exact service chosen. Check your policy’s language: if it says “cremation or burial,” ask the insurer whether natural organic reduction is included. Colorado law does not require insurers to cover NOR specifically.

How do I find a licensed NOR facility in Colorado?

Start with DORA’s NOR licensee list at dpo.colorado.gov/NOR. The page keeps a current roster of licensed facilities with contact information. As of mid-2026, at least three active licensees operate in the state: The Natural Funeral in Lafayette, Be a Tree in Denver, and a newer facility near Colorado Springs. Verify the license status before contracting; ask for the license number and cross-check with DORA.

What’s the difference between natural organic reduction and green burial?

Green burial places an unembalmed body directly in the earth in a biodegradable shroud or casket, letting decomposition happen underground. Natural organic reduction happens in an above-ground vessel under controlled conditions, producing soil that returns to the family. Both avoid toxic chemicals and concrete vaults. In Colorado, both are legal, but they require different permitting if you operate a facility. NOR licenses are separate from cemetery or burial permits.

Does human composting generate methane or other greenhouse gases?

A properly managed aerobic NOR vessel produces mostly carbon dioxide and water vapor, not methane. Anaerobic pockets can form if the pile goes unturned, but licensed facilities monitor airflow and temperature. The Washington State University study Colorado relied on found that NOR avoids the fossil fuel combustion of cremation and produces fewer greenhouse gases than conventional burial once you factor in concrete and transportation. ^[5]

Can I preplan and prepay for my human composting in Colorado?

Yes. Most NOR providers offer pre-need contracts. Colorado law governs pre-need funeral contracts through the state’s pre-need funeral contract statute (CRS 10-15-101, etc.). Funds must sit in trust or an insurance product. A prepaid contract locks in the price at purchase. Review the contract’s portability: if you move out of state, can you get a refund? Confirm the provider’s license is current both when you sign and when services are rendered.

How many bodies can a NOR facility process at once under Colorado law?

Colorado’s rules allow multiple human remains in a single vessel under strict tracking. Rule 8.7 requires that each body stay identifiable throughout the process through a unique identifier, location in the vessel, and physical separation that prevents commingling of residual bone particles. Many facilities choose single-body vessels to keep chain-of-custody simple. If a facility uses a multi-body vessel, the renewal application must describe the segregation protocol, and DORA may inspect it during the year.

Are there religious or ethical objections to human composting I should consider?

Some religious traditions have not formally weighed in on NOR. The Catholic Church in the U.S. has said green burial is consistent with the dignity of the body but has not issued an official statement specific to natural organic reduction. Others see the process as a return to the earth consistent with their beliefs. If you operate a facility, keep clear informational materials for families and respect their right to ask questions. Colorado law requires informed consent for all disposition methods.
