How human composting works in Washington
Human composting in Washington is an eco-friendly alternative to cremation and burial, also called soil transformation, body composting, natural organic reduction, or terramation.
With Earth, a person’s remains are placed in a vessel with natural materials and, over 45 days, are gently transformed into soil. When complete, families can request soil for a memorial garden, to plant a native tree, or to spread in a meaningful place that follows local regulations. Earth donates the remaining soil to conservation work across Washington, supporting land restoration and new growth.
Many in Washington choose human composting because it matches how they live, spending time outdoors and wanting their last act to give back to the forests, shorelines, and communities they love.
