Human Composting FAQs
How it Works
Human composting, also called natural organic reduction or soil transformation, is a form of disposition that transforms a body into soil. The biological process mimics the earth’s natural cycles and is similar to what occurs on the forest floor as organic material decomposes and becomes topsoil. The process of human composting happens inside of a vessel and is carefully monitored by certified professionals.
History of Human Composting
Human composting was originally conceived by founder Katrina Spade in 2011, and developed by Recompose over years of rigorous research and design. Human composting was first legalized in Washington State in 2019 and is now legal in multiple states across the country.
How Human Composting Works
Human composting typically takes between 8 to 12 weeks from the time a body is laid into a composting vessel until the soil is ready to be returned.
The Laying In
At the time of laying in, the body is placed into a composting vessel, a steel cylinder, 8 feet long and 4 feet tall. The body is surrounded by a mixture of wood chips, alfalfa, and straw carefully calibrated and specially tailored to each individual. The vessel closes and the transformation into soil begins.
The Vessel Phase
The temperature inside the vessel rises over time as the microbes work and is sustained over 131 degrees Fahrenheit for a minimum of 3 continuous days. Over the next five to seven weeks, the body breaks down thanks to the natural action of aerobic microbes. Recompose staff monitor the temperature inside the vessel to determine when a rotation is needed to increase oxygenation and expose additional energy to the microbes.
The Curing Phase
The soil is removed from the vessel and placed in a curing bin where it is aerated for an additional three to five weeks. Curing compost is still an active, living material that will continue to experience changes and reduce in weight and volume.
The Soil
Each body creates about a cubic yard of soil, weighing between 500 to 1,000 pounds. The nutrient-rich soil is ready to grow new life and returns nutrients from our bodies to the natural world. It sequesters carbon and nourishes new life in gardens, forests, and on conserved lands.
Environmental Impact
Human composting uses 87% less energy than traditional burial or cremation and saves one metric ton of carbon pollution That’s equivalent to the CO2 emissions of driving 2,481 miles or 1,102 pounds of coal.
Funeral practices like cremation and embalming have a profound impact on the environment. Each year, about 3 million people die in the U.S. 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 the resource-intensive manufacture and transport of caskets, headstones, and grave liners. Every year in the U.S., caskets alone use 4 million acres of forest.
Human composting is the 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 the natural action of the microbes. The soil is then removed from the vessel, screened for non-organic items such as hip replacements or stents, and allowed to 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.

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 exposure to resources for the microbes.
Bones are reduced to a fine powder by equipment after the soil is removed from the Recompose vessel. Staff also screen for non-organics such as implants, which are recycled whenever possible. The reduced bone is added back to the compost to help balance the compost nutrients and make 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.
The entire human composting process generally takes between eight to twelve weeks. Our staff communicate timing and key moments throughout the process. Each body spends about five to seven weeks in a Recompose vessel, then the soil is transferred to an aerated bin to cure for an additional three to five weeks.

Human composting saves carbon through a combination of factors. The process uses 87% less energy than cremation, which typically uses fossil fuel to create sustained heat of over 1,600 degrees Fahrenheit for 3 to 4 hours.
No casket or coffin is used during human composting, nor is a concrete grave liner required – all items that add to the carbon footprint of a death.
When human composting transforms the organic material of our bodies, the carbon is captured, or sequestered, in the soil created. Rather than being released as carbon dioxide gas through exhaust during a cremation or as a hydrocarbon gas like methane, the carbon contained in each body returns to the earth. As the nutrients in the compost are used over time by the plants in contact with it, the impact of a person’s choice for human composting continues to expand exponentially.
The Recompose human composting process creates approximately one cubic yard of soil per body which is roughly 3 x 3 x 3 feet. This amount fills the bed of most pickup trucks and weighs about 1,000 pounds. The process begins with three cubic yards of plant material.
Families can take some or all of the soil home once the process is complete, and donate what does not go home to conservation efforts. Learn more about how to consider your soil options.
Human composting takes place in a closed, reusable vessel while green burial refers to the practice of burying an unembalmed body in a designated green burial cemetery with a simple casket or shroud. Both human composting and green burial encourage natural decomposition.
Human composting is not a type of burial because the body is not placed in the ground. Human composting creates an environment in which beneficial microbes thrive, with a specific moisture content and ratio of carbon and nitrogen materials. The molecular processes power human composting are the same processes that break down a body during green burial. However, these processes typically take much longer in a green burial context. This is partly because not as much oxygen reaches a body that has been buried underground.
Conceptually, both green burial and natural organic reduction return a body to the earth. Both processes are part of a worldwide movement to make death care practices less harmful—and ideally beneficial—to the planet.

Planning for Human Composting
You can choose Recompose for human composting from most states. You can contact our staff at (206) 800-8733 or precompose@recompose.life and we can help you arrange for transport.
Most clients that come to us from another state work with a funeral home in their area to arrange for transport. This funeral home will pick up a body at the place of death and arrange for transport to Recompose. When you contact a funeral home, we suggest starting the conversation by saying something like, “I am looking to have my body transported to the Seattle area. I have chosen a funeral home called Recompose to handle my death care services. Can you help me make arrangements?”
In most instances, families can also transport their person to Recompose in their personal vehicle with the correct permits. If you are interested in this option, please contact us and we’re happy to help.
Please note: Bodies that come to Recompose must not be embalmed. While most funeral homes are experienced with transporting bodies, they may not yet have heard of human composting or have experience with this kind of transport. If you have any questions or need help finding a transporting funeral home, Recompose staff can help you.
Our article, How to Arrange for Transport to Recompose, also has information to help you.
Recompose aims to keep our costs comparable to other death care options. Our $7,000 includes empathetic care and guidance from our Services team from the time of death through transformation into soil 8 to 12 weeks later.
According to a 2023 study conducted by the National Funeral Directors Association, the median cost for a funeral with a coffin and burial is $8,300 (not including the burial plot itself, which can range from the hundreds to the tens of thousands) and the median cost for cremation is $6,280.
We strive to be straightforward about our pricing and services so you are informed and know what to expect. Recompose operates with integrity and clarity and will never try to upsell you. Learn more about our services and find a list of current pricing for all services in our General Price List.
We are committed to bringing ecological death care to as many people as possible. This includes providing our services at a subsidized rate to individuals who could not otherwise afford to pay our full price through our Community Fund.
Yes, you can donate your organs and choose human composting.
Organs will be removed by medical professionals at the time of death. Recompose, or the local funeral home you’re working with in your state, will coordinate transportation back to the funeral home with the organ donation company or medical facility.
Organ donation is different from donating a body to medical science, where the body is embalmed and therefore cannot undergo human composting. Organ donation can only occur if you die in a hospital because they need specific equipment to keep the organs viable until the donation company arrives. Organ donation companies do not embalm bodies, and the organ donation process is typically completed within a couple of days.
Willed body programs, also called full body donation, embalm bodies and typically keep them for 1-2 years in universities and other medical institutions where medical professionals and students study them. Embalmed bodies cannot undergo human composting.
The soil created by human composting is biologically 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 6.5 – 7 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 State, the law for scattering human composting soil is the same for cremated remains—you must have permission of the landowner. It is legal to scatter in navigable waterways.
