Also known as “natural organic reduction,” terramation gently transforms human remains into nutrient-rich soil, just like the soil found at plant nurseries.

Our terramation process takes place inside individual pods, where a body is transformed into earth over a period of approximately 60 days. The pods are designed to optimize carbon, nitrogen, moisture, oxygen, and temperature to create the perfect environment for naturally occurring microbes to conduct the transformation. In the last step, we screen for inorganics so that the soil is entirely pure. The end result yields about one and a half cubic yards of fertile earth for the family to use as they see fit.

Terramation is ruled out only in rare cases where the cause of death is a prion-related illness, such as Creutzfeldt-Jakob, or a highly infectious disease, like Ebola.

Yes, terramation is now legal in Washington State! In May 2019, Governor Jay Inslee signed SB5001 into law, which allows for natural organic reduction (“the contained, accelerated conversion of human remains to soil”) as a disposition option for human remains. The new law went into effect on May 1, 2020. 

Individuals and their families may decide how to use the soil. The soil is rich in life-giving nutrients and marvelously fertile, making it ideal for gardens and landscapes. Use it to create a memorial flower bed or to plant a tree. Return Home will pack up and deliver as much of the terramationed earth as desired. Any unclaimed earth will be donated to park departments, land trusts, and the like to improve soil health in the region.


In many ways, terramation and cremation are opposites. Transforming our remains into living soil supports the flourishing of future life; converting them to ash breaks the cycle of life, sending our matter up in smoke.

Unfortunately, cremation comes with a host of environmental problems. For one, it is extremely energy-intensive: a single cremation burns about 30 gallons of fossil fuel, or enough to drive from Los Angeles to San Francisco and back, and total U.S. cremations annually emit 250,000 tons of CO2. In addition, the cremation of dental fillings is a major contributor to mercury air pollution, releasing 2–4 grams of mercury per cremation, or about 5,000 pounds of mercury per year.

Terramation is not the same thing as “green burial.” Though green burial is a more earth-friendly disposition method, it still demands a plot in a graveyard at a time when we are rapidly running out of burial space. In the U.S. alone, it would require roughly 130 square miles of additional grave space every year to bury all our dead, which is clearly not sustainable. Terramation solves the land constraint problem by bypassing the graveyard.
