Natural organic reduction (NOR) was developed as an environmentally conscious alternative to conventional burial or flame cremation. It is a process that accelerates the natural decomposition of human remains into soil. You may also hear it called human composting or terramation.
Families are drawn to this option because it allows their loved one to become part of the natural cycle, transforming the body’s organic materials into nutrient-rich soil, particularly in a setting where there are no green cemetery options nearby.
Natural organic reduction has a smaller environmental impact than traditional methods of caring for the body after death. The process uses less energy than flame cremation, and it does not release pollutants into the air. Unlike traditional burial, it does not use burial vaults or metal caskets, and it avoids the toxic chemicals used in embalming. And since it does not require dedicated space for an individual permanent resting place, it may be a good choice for urban environments where land is expensive and green burial sites are unavailable.
How it works
In natural organic reduction, the body is placed in a large, enclosed vessel designed for the process. Medical devices such as pacemakers are removed. Bodies that have been embalmed cannot undergo the process, and a few uncommon infectious diseases also preclude it.
Inside the vessel, the body is surrounded by easily biodegradable materials such as wood chips, straw, and alfalfa. These materials allow air to circulate and create the right conditions for decomposition. Naturally occurring bacteria and other tiny organisms begin breaking down the body, similar to the way organic matter decomposes in nature.
Facilities carefully manage the environment inside the vessel by maintaining warm temperatures and monitoring moisture and oxygen levels. The materials may be periodically rotated or turned to support the process. The active reduction stage usually takes about four to six weeks.
Afterward, the material is screened and remaining bone fragments are dried and processed into a fine powder, similar to cremated remains. The powder is then added back, and the material is allowed to cure for additional time. The process typically produces about one cubic yard of soil, which is roughly the volume of a large garden bed. Facilities test the material to confirm it meets safety standards.
Families may use some or all of the soil in an ornamental garden or tree planting, keep the soil, or scatter a small portion of it, subject to the restrictions in each state where the process has been legalized. Natural organic reduction facilities have agreements in place with nearby conservation or land restoration projects that can use the remainder of the soil.
Availability
Natural organic reduction was first legalized for human remains in Washington State in 2019. Since then, several other states have approved the practice. As of 2026, it is legal in 12 U.S. states, including Maryland and Delaware, though it is not currently legal in Washington, D.C.
Even where it is permitted by law, natural organic reduction is not yet widely available. Facilities require specialized equipment and must meet state regulatory requirements, and public awareness of the practice is still relatively low. In Maryland, a facility planned near Baltimore is expected to open in 2026 and will be positioned to serve a large area in several eastern states.
Because the number of facilities in the U.S. is still small, those that are now open accept bodies from other states. Families should be aware that transporting a body long distances can significantly increase the overall cost.
The cost of natural organic reduction varies depending on the provider and the services a family wants. The reduction process itself generally costs between $5,500 and $7,000. Additional costs may include transportation, a laying-in service (when family and friends are present at the beginning of the process), other memorial services, or the return or distribution of the soil.
Natural organic reduction is gaining popularity as an environmentally friendly alternative to traditional burial and cremation, with minimal impact on the earth’s resources. For some families, it represents a gentler, more natural approach to honoring a loved one’s life and values.
