It is our mission to make the death care process as straightforward and as gentle as possible.

What is the composition of human composting soil?

Human composting creates a compost ideal for most plants. Human compost can be used on trees, yards, house plants, and flower gardens, just like any other type of compost (such as compost created by food scraps or garden prunings).

All compost that completes the human composting process is tested by both Recompose and a third-party lab for safety. Additional analysis indicates compost that is good for use on plants. The pH range of Recompose compost is usually between 6.5 and 7, which is ideal for most plants. Electrical conductivity is moderate, indicating the presence of soluble (plant-available) ions. As a fertilizer, the nitrogen-phosphorus-potassium-sulfur content is balanced, providing good nutrient content with a good supply of macronutrients.

Respiration test results indicate Recompose compost is at “Very Stable” levels, indicating that most of the “fast pool” of sugars have been used up by microbes and nutrients are stabilized. Nitrate content is high, indicating aerobic status and advanced decomposition. Bioassay does show relative immaturity, so we recommend use at lower concentration around roots of young plants.

Land Acknowledgement

Recompose acknowledges we make our lives and livelihoods on the lands of the Coast Salish People, specifically the Duwamish People. We honor with gratitude the Duwamish People past and present, the land itself, and the Duwamish Tribe.

Colonization is an active, persistent process. Indigenous communities continue to be resilient in protecting their ecological and cultural lifeways and deathways despite ongoing oppression. Recompose respects, shares, and supports this commitment to climate healing and environmental justice. Join Recompose in contributing to Real Rent Duwamish.
