Human Composting California: What's Legal Right Now and What Isn't

California legalized human composting in 2022. Governor Newsom signed Assembly Bill 351, making California one of only a handful of states to recognize natural organic reduction — the formal term for human composting — as a legal form of disposition alongside burial, cremation, and aquamation.

Here's the problem families run into: the law is on the books, but as of 2026 there is no licensed human composting facility operating inside California. The California Cemetery and Funeral Bureau will not accept applications to open in-state facilities until 2027. That gap between what's legal and what's accessible creates a specific logistical challenge for any California family trying to choose this option today.

This article explains exactly what natural organic reduction involves, what you can legally do right now, and what the full permitting process looks like.

What Natural Organic Reduction Actually Is

Natural organic reduction — sometimes called terramation or human composting — is a disposition method in which human remains are placed in a vessel with organic material such as wood chips, straw, and wildflowers. Over approximately 30 to 45 days, microbial activity transforms the body into roughly a cubic yard of nutrient-rich soil. The process is accelerated through temperature regulation and aeration, maintaining conditions that neutralize pathogens and break down bone.

The resulting soil material can be returned to the family, used on private land, or donated to conservation efforts. Families who cannot have a body returned via cremation ashes due to personal or religious reasons sometimes find natural organic reduction offers an alternative kind of physical return.

The environmental argument for it is direct. Human composting uses a fraction of the energy required for flame cremation and eliminates the formaldehyde introduced into the ground through embalming. It is legal in Washington, Oregon, Colorado, Vermont, Nevada, Hawaii, Minnesota, and now California — though only Washington and Oregon have well-established commercial facilities.

The 2026 Reality: No Licensed Facilities in California

AB 351 authorized natural organic reduction but instructed the California Cemetery and Funeral Bureau to develop regulations and a licensing framework before any facility could open. That regulatory process has a statutory deadline: the CFB cannot accept license applications until January 1, 2027.

What this means practically is that any California family who wants natural organic reduction in 2026 must arrange for out-of-state transport of the remains to a licensed facility — most commonly in Washington state.

This is entirely legal. California law permits the transportation of unembalmed remains across state lines under specific conditions, and out-of-state human composting is treated as a valid disposition method for VS-9 permitting purposes. But it adds logistical complexity and cost.

How to Pursue Human Composting from California in 2026

If you want to move forward with natural organic reduction before California's in-state facilities open, here is how the process works:

Step 1: Work with a California funeral home that specializes in green disposition. You need a licensed funeral director in California to execute the initial removal, file the death certificate (VS-11 form), and obtain the VS-9 permit for disposition. The VS-9 must explicitly name the out-of-state facility as the destination. You cannot simply drive remains across state lines without this paperwork.

Step 2: Arrange refrigerated interstate transport. Human remains intended for natural organic reduction cannot be embalmed — embalming involves formaldehyde, which would disrupt the microbial process. California Health and Safety Code Section 7355 requires that un-embalmed remains transported via common carrier be sealed in an airtight metal casket or specialized container. For ground transport via private specialized carrier — which is what most out-of-state composting facilities arrange — the requirements are different and more flexible. Your California funeral director will coordinate the logistics.

Step 3: Contract directly with the out-of-state facility. Washington-based facilities like Recompose have processed remains from out-of-state families and have established protocols for California transfers. They typically handle coordination of their receiving state's paperwork once the California VS-9 is issued. Expect the full cost — California funeral home fees plus transport plus the facility fee — to run considerably higher than direct cremation.

Step 4: Plan for soil return or donation. The facility will advise on timing. Most natural organic reduction cycles complete within four to six weeks. You can request the resulting soil be shipped back to California or designated for a specific conservation partner.

The California Funeral Laws & Consumer Rights Guide covers the full VS-9 permitting language, interstate transport rules, and what to expect from each step of coordinating a disposition that crosses state lines.

What Changes in 2027

Once the California Cemetery and Funeral Bureau begins accepting license applications in 2027, in-state natural organic reduction facilities can open. The regulatory framework will establish:

• Facility construction and sanitation standards
• Soil testing requirements to certify pathogen reduction
• Chain-of-custody documentation for remains throughout the process
• Rules for soil distribution and land application

When those facilities open, the process will become substantially simpler — and likely less expensive — for California families. You would work directly with a local facility the way you currently work with a local crematory.

Human Composting and the VS-9 Permit

One detail many families miss: the VS-9 disposition permit must specify the method and the location of final disposition. For natural organic reduction, the VS-9 should indicate the method as "natural organic reduction" and identify the receiving facility by name and address in the destination state.

If the soil is ultimately returned to California for scattering or land application after the reduction process is complete, that final act of scattering may require its own separate VS-9 for the California disposition. California is strict about requiring a permit for each distinct final disposition location — including division of remains across multiple sites.

Choosing Human Composting: Questions to Ask

Before committing to this option, ask the receiving facility:

• What documentation do they need from the California funeral home before accepting the remains?
• What is the turnaround time for the reduction process?
• Can soil be shipped back to California, and are there any restrictions on its use?
• Is the facility licensed in their state, and can they provide that documentation?
• What is the total all-in cost, including their fee, transport, and any California funeral home coordination fees?

Natural organic reduction is a legitimate and fully legal disposition option for California residents right now. The path is just longer than it will be once in-state facilities open. Understanding the process in advance — especially the VS-9 requirements and transport rules — prevents the paperwork bottlenecks that derail timelines when families try to navigate it alone.
