Discover the Green Alternative to Cremation or Burial

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.

The human composting process generally takes between two to three months. Our staff communicate timing and key moments throughout the process. Each body spends about five to seven weeks in a vessel, then the soil is transferred to an aerated bin to cure for an additional three to five weeks.

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. Learn more about the composition of Recompose soil here.

Human composting is a more environmentally-friendly option than burial or cremation. This is because the process does not use fossil fuel like cremation, does not require the casket and cemetery resources of burial, and sequesters carbon as soil is created. 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.

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.

Our work is rooted in nature, with innovation and sustainability at the core of our operations. In 2011, our founder, Katrina Spade, began developing a scalable, ecological urban alternative to conventional burial and cremation. After successfully leading grassroots legislation efforts to legalize human composting in Washington State in 2019, Recompose became the first facility in the world to offer this service.

Our process saves over a metric ton of carbon emissions per person compared to conventional death care, while creating nutrient-rich soil that supports new life. But sustainability at Recompose goes far beyond environmental impact.

We approach sustainability holistically, recognizing that long-term environmental health is inseparable from social equity and economic viability. Every decision we make prioritizes lasting impact over short-term gain.

Some examples of our commitment to sustainability

• The Recompose Land Program partners with carefully selected nonprofit organizations working to reverse habitat and biodiversity loss, giving Recompose clients the option to donate soil and contribute to the greater good. 
• Durable composting vessels, made from stainless steel in the U.S. and designed to last over 70 years.
• The Recompose Community Fund helps make human composting accessible to those who may not otherwise afford it.
• Responsible material handling, including screening soil for non-organic matter and recycling metals that families choose not to keep.

When you are ready, Recompose will arrange transport of your loved one into our care. Transportation arrangements to Recompose are dependent on location.

Within Washington and the Portland Metro Area

At the time of death, our Services team will coordinate transportation and logistics to bring the body from the place of death into our care at Recompose.

• If your person dies in a hospital or care facility, you can let the facility staff know that Recompose is your funeral home of choice, and they will notify us of the death for you.
• If your person’s body is at home, let us know when you are ready for Recompose to arrange to have your person safely delivered into our care.

Transportation of the body to Recompose is complimentary from anywhere within our service area.

Outside Our Service Area

If you live outside Washington or the Portland metro area, we’ll coordinate transportation with a local funeral home. Many Recompose clients come to us from out of state, and our team has extensive experience guiding clients through the process.

• If you have not yet selected a local funeral home, we are available to help research options for you.
• If you have already selected a funeral home you’d like to work with, we will coordinate with them to have your person safely delivered into our care.

The cost of transportation to Recompose from outside our service area is determined and billed by the local funeral home you choose to work with.

Recompose can ship soil to most locations in the U.S. However, due to the variety of regulations involved, Recompose does not ship soil internationally.

Recompose packages soil in durable paper bags that hold about 12 gallons each. These sealed bags are similar to the size of the compost or potting soil bags you find at the garden store. On average, each person produces between 25-40 bags of soil, weighing about 20 pounds each. Any amount of soil can be ordered in our standard packaging, which is included in our price.Note: the cost of shipping soil is not included. Shipping costs vary by package quantity, dimensions, and weight.

Our article How to Consider Your Soil Options is a useful resource when deciding how much soil to pick up, ship, or donate. The Recompose Services Team is also available to discuss your options. Contact them at services@recompose.life or by calling (206) 800-8733.

Recompose partners with conservation organizations, so you can choose to donate some, or all, of the soil to nourish and revitalize the land.

Through the Recompose Land Program, you have the opportunity to donate soil to help restore and revitalize land stewarded by nonprofit conservation organizations. Our Land Partners protect and regenerate ecosystems through conservation, rewilding, and other restoration practices.

Many Recompose clients choose to donate some soil to the Land Program and take a portion to share with friends and family to use on gardens, on house plants, and scatter across favorite places.

Through the Recompose Land Program, we partner with nonprofit organizations to protect and regenerate ecosystems through conservation, rewilding, and other restoration practices. These Land Partners receive soil donated from Recompose clients to use in projects that benefit the land they steward.

Our Land Partners focus on ecologically significant areas across diverse, protected landscapes like forests, prairie grasslands, and wetland areas. Some of the many species that are supported through soil donation include:

• Elk
• Beaver
• River otter
• Black-tailed deer
• Juvenile salmonids

Recompose is proud to support this work to allow nature to flourish again. 

Clients who choose to donate soil through the Land Program have shared that they connect with the concept of returning to the natural environment as a whole rather than to a single location—instead of becoming a tree, they become part of the forest.

Recompose and our Land Partners share a common interest in connecting the human experience with the natural environment, and recognize the use of soil from human composting as a way to strengthen this connection.
