Human Composting in South Dakota: Current Legal Status and Alternatives

Natural organic reduction — marketed under names including human composting, soil transformation, and terramation — is the process of converting human remains into nutrient-rich soil through a controlled, accelerated decomposition process. For families drawn to this option for environmental or philosophical reasons, the key question is whether it is available where they live. In South Dakota, the answer is currently no.

Human Composting Is Not Legal in South Dakota

As of mid-2026, South Dakota has not enacted legislation authorizing natural organic reduction (NOR). The state's legal framework for disposition of human remains recognizes burial (in-ground interment), cremation (including alkaline hydrolysis, which South Dakota explicitly legalized), and a limited set of alternative methods — but NOR is not among them.

This is not unique to South Dakota. NOR is a newer technology, and the legal landscape is still developing state by state. The process produces cubic yards of soil material over a period of weeks in a specialized vessel, presenting regulatory challenges around environmental placement, pathogen control, and land use that differ significantly from cremation. States legalizing NOR have had to develop new statutory and regulatory frameworks from scratch.

The South Dakota legislature has not passed any bill legalizing or authorizing human composting. Families who specifically want NOR would need to arrange for disposition in a state where it is available, which involves transporting the remains.

Why the Status Differs From Aquamation

It's worth understanding why South Dakota legalized aquamation but has not yet addressed human composting. The legislative approach to aquamation was straightforward: the state amended the existing statutory definition of "cremation" to include alkaline hydrolysis, which immediately brought it under the existing cremation regulatory framework with no new infrastructure needed.

NOR cannot be handled the same way. The end product is soil, not bone fragments. The timeline is weeks, not hours. The regulatory questions around who may receive the soil (and in what quantities), where it may be placed, and how facilities are licensed and inspected require a distinct legal framework. Advocates have worked to introduce legislation in multiple states, and the list of states that have passed authorization continues to grow — but South Dakota has not yet acted.

If you are interested in this option and reside in South Dakota, there is value in contacting your state legislators to express support for legislation that would authorize NOR in the future. The issue has active advocacy behind it, and the legislative momentum in other states is real.

States Where Natural Organic Reduction Is Available

The following states had legalized NOR as of mid-2026 (this list expands periodically):

• Washington (the first, legalized in 2019)
• Colorado
• Oregon
• Vermont
• California
• New York
• Nevada
• Arizona
• Minnesota
• Maine
• Maryland
• New Mexico
• Connecticut
• Illinois

If you reside near a state border and are willing to arrange out-of-state disposition, this may be a practical option. The process requires transporting the remains to a licensed NOR facility, which means coordinating with a funeral home in South Dakota to obtain the disposition permit and manage the transport, then working with the NOR provider in the receiving state.

The cost and logistics are higher than in-state options, but the process is legally permissible. A disposition permit under SDCL 34-25-24 would be required for transport of the remains out of South Dakota, and the receiving state's requirements would govern the NOR process itself.

The South Dakota Funeral Laws & Consumer Rights Guide covers the full range of disposition options currently available in South Dakota — including what is and isn't legal — and the legal requirements for transporting remains to other states.

Eco-Friendly Alternatives Available in South Dakota Right Now

For families interested in environmentally conscious disposition but unwilling or unable to arrange out-of-state services, South Dakota offers several alternatives:

Alkaline hydrolysis (aquamation). South Dakota legalized aquamation through an amendment to SDCL 34-26A-1, which defines cremation to include "alkaline hydrolysis." Water cremation is generally considered to have a significantly lower environmental impact than flame cremation — less energy use, no atmospheric emissions. Availability is growing but not yet universal in South Dakota.

Green burial. No casket, no embalming, no concrete vault — direct interment in a biodegradable shroud on land that permits it. South Dakota does not require a casket by law, making green burial a legally accessible option. Private land burial is available for families who own suitable property and comply with the platting and permit requirements.

Home burial. For rural families who own agricultural land, home burial with a biodegradable container (or no container at all) is a legally viable option under South Dakota law, provided the permit and recording requirements are met.

These options won't produce the soil that NOR provides, but they offer meaningful reductions in environmental impact compared to traditional embalmed burial in a concrete vault.

As South Dakota's legislative environment evolves, the legal options for disposition will continue to expand. Monitoring the South Dakota legislature's session each year is the best way to track whether NOR authorization is on the agenda.
