Our Model
Recompose uses a process called natural organic reduction to transform human remains into soil. This soil can then be used to regenerate the earth that supports us our whole lives.
Environmental Impact
Recompose utilizes the principles of nature to return bodies to the land, sequestering carbon and improving the health of our natural surroundings.
Healing the Climate
For every person who chooses Recompose over conventional burial or cremation, one metric ton of carbon dioxide is prevented from entering the atmosphere. In addition, our approach to human composting requires 1/8 the energy of conventional burial or cremation. Recompose allows you to choose an end-of-life option that strengthens the environment rather than depleting it.
Moving Away from Toxic Practices
Current funerary practices are environmentally problematic. Each year, 2.7 million people die in the U.S., and most are buried in a conventional cemetery or cremated.
Cremation burns fossil fuels and emits carbon dioxide and particulates into the atmosphere. Conventional burial consumes valuable urban land, pollutes the soil, and contributes to climate change through resource-intensive manufacture and transport of caskets, headstones, and grave liners. The overall environmental impact of conventional burial and cremation is about the same.
Creating Soil Health
The breakdown of organic matter is an essential component in the cycle that allows the death of one organism to nurture the life of another. Soil is the foundation of a healthy ecosystem. It filters water, provides nutrients to plants, sequesters carbon, and helps regulate global temperature.
The Process
The graphic below illustrates how the Recompose approach to human composting works. Microbes, oxygen, and plant matter combine to gently convert human remains into soil.
PHASE 1
The Cycle Begins
Human composting is powered by beneficial microbes that occur naturally on our bodies and in the environment.
PHASE 2
The Laying In
Our staff lay the body in a vessel surrounded by wood chips, alfalfa, and straw. The vessel is closed and the transformation into soil begins.
PHASE 3
The Vessel
The body and plant material remain in the vessel for four to seven weeks. Microbes power change on the molecular level, resulting in the formation of a nutrient-dense soil.
PHASE 4
The Soil
Each body creates one cubic yard of soil amendment, which is removed from the vessel and allowed to cure for three to five weeks. Once completed, it can be used to enrich conservation land, forests, or gardens.
PHASE 5
Life After Death
The soil created returns the nutrients from our bodies to the natural world. It restores forests, sequesters carbon, and nourishes new life.
The Forest
Each body that completes the Recompose process creates one cubic yard of nutrient-rich soil amendment. We offer the opportunity to donate this soil to Bells Mountain, a 700-acre nonprofit land trust in southern Washington.
Welcome to Bells Mountain
This forest is a legally protected natural wilderness and will remain so in perpetuity. The land’s caretakers use the soil donated by Recompose to support the continued revitalization of wetlands, riparian habitats, local plants, and vulnerable wildlife species. Bells Mountain and its ecological restoration is managed by Remember Land, a 501(c)(3) nonprofit organization.
The Forest Needs You
Following a century of abuse and neglect, cleared lands battered by sun and wind are left with degraded soils and stunted forests. The soil Recompose delivers will enrich recovering clear-cut fields, helping them to flourish once again.
Healthy soil empowers agroforestry, holistic range management, and ecological development, all of which reduce negative climate impacts and contribute to the regeneration of natural ecosystems.
Our Location
Recompose is a licensed green funeral home in Seattle supporting clients across the U.S. Our experienced funeral directors provide personalized support throughout the entire death care journey.
The Space
This beautiful and intimate space in Seattle’s SODO neighborhood is designed for friends and family to honor the person who has died. We have 54 vessels at this location where bodies are transformed into soil.
The Laying-In
Our Gathering Space offers the opportunity to honor loved ones during an in-person or virtual laying-in ceremony. Much like the moment when a body is interred into the earth during a burial, the laying-in represents a moment of transition.
The Vessels
The transformation from human to soil takes place inside a Recompose vessel. Your loved one’s body is surrounded by wood chips, alfalfa, and straw in the vessel and is closely monitored while microbes naturally break the body down into soil.
FAQ
Please see below for more detailed information about the process, the environmental impact, and how Recompose differs from other human composting options. These FAQs offer an additional layer of detail to questions about why this process is needed and the science behind its safety and efficacy.
How It Works
- Human composting is the gentle transformation of a human body into soil. Recompose places each body into a stainless steel vessel along with wood chips, alfalfa, and straw. Microbes that naturally occur on the plant material and on and in our bodies power the transformation into soil. Over the next five to seven weeks, the body inside the vessel breaks down thanks to natural decomposition. The soil is then removed from the vessel, screened for non-organic items such as hip implants or pacemakers, and allowed to dry and cure for an additional three to five weeks. Once the process is complete, the soil can be used on trees and plants, or donated to conservation efforts. Each body creates about one cubic yard of soil amendment.

Bones and teeth do not fully break down in the human composting process due to their mineral composition. Similar to other forms of death care, equipment is needed to reduce the bones.
Microbes do the primary work of human composting. By controlling the ratio of carbon, nitrogen, oxygen, and moisture, human composting creates the perfect environment for microbes and beneficial bacteria to thrive. To create that environment, Recompose uses a mixture of plant materials carefully calibrated and tailored to each body.
Recompose staff rotate each vessel at several points during the process to ensure thorough aeration and decomposition. Staff also screen for non-organics such as implants, which are recycled whenever possible.
Bones are broken down when the soil is removed from the Recompose vessel. The reduced bone helps balance the compost and makes minerals available to plants. It continues to break down and return to the environment over time.
Recompose follows all compost-testing regulations put forth by the Washington State Department of Licensing and the Board of Health. The pH range of Recompose compost is usually between 6.5 and 7, which is ideal for most plants.

Environmental Impact
- Human composting is a more environmentally-friendly option than burial or cremation. This is because the process does not use fossil gas like cremation, does not require the casket and cemetery resources of burial, and sequesters carbon as soil is created. To measure the environmental impact of human composting, expert Dr. Troy Hottle developed a scientific model to compare cremation, conventional burial, green burial, and human composting. The model showed that human composting and green burial perform far better than cremation or conventional burial at reducing carbon. The research showed that between .84 and 1.4 metric tons of carbon dioxide will be saved each time someone chooses human composting.
- Human composting saves carbon through a combination of factors. The process uses about 87% less energy than cremation, which uses fossil gas to create heat of over 1,400 degrees Fahrenheit. When human composting transforms the organic material of our bodies, carbon is also sequestered in the soil created. Rather than being released as carbon dioxide gas through exhaust during a cremation, the carbon matter contained in each body returns to the earth.
Soil Information
- Human composting creates one cubic yard of soil per body. The process begins with three cubic yards of plant material. Families can either take the soil home once the process is complete, or they can donate some or all of the soil to conservation efforts.
- 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). 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. Recompose follows all compost-testing regulations put forth by the Washington State Department of Licensing and the Board of Health.
- The soil created by human composting is valuable material that can be used to nourish trees and plants. It can be used in yards, flower gardens, trees, house plants, and in natural environments. Its pH of 6.6 is ideal for most plants. It has a balanced nutrient content with a good supply of macronutrients. Recompose customers have used their person's soil to create groves of trees, nourish rose gardens tended by their person while they were alive, or scattered in a favorite natural area. In Washington, the law for scattering human composting soil is the same for cremated remains: You must have permission of the land owner in order to use the soil from human composting on private land. It is also legal to scatter in navigable waterways. If you have any questions about what you can do with your soil, our staff is happy to help.
Legal
- In the United States, human composting is legal in Washington, Colorado, Oregon, Vermont, California, and New York. Recompose is currently open in Washington State, and plans to open in Colorado and California in the coming years. We are partnering with lawmakers to legalize human composting in more states and, eventually, around the world. Read about our efforts on our Public Policy page. Curious how human composting becomes law? While each state is different, we wrote an article about what it takes to legalize human composting.
- Recompose's mission is to bring human composting everywhere there are people who want it. We’ll announce all future expansions via our newsletter. In the U.S., the laws governing human remains vary greatly from state to state, as do the processes for passing new laws. Because of this, we don’t have an easy template for how to pass human composting laws in new states but we've created an article about how human composting becomes law to give you a sense of what goes into the process. Talking to friends and family about your end-of-life wishes and why Recompose is meaningful for you is a great way to start building interest and demand in your area. As Recompose expands, the number of people who are interested in our service is a big factor in choosing which states we pursue next. You can read more about this on our Public Policy page.
