What is human composting?
Human composting is a new choice for those who seeking an alternative to burial or cremation. It’s the process of transforming a loved one into soil that can be used to plant trees or flowers or be spread on conservation land on Washington’s Olympic Peninsula.

Who is eligible?
Most people are eligible for human composting. There are some exclusions, including those who:
- Have radioactive implants.
- Died as a result of a radiological incident or accident.
- Had, or were suspected of having, prion disease, mycobacterium tuberculosis or Ebola.
At this time we are also unable to accommodate loved ones heavier than 250 pounds.
Where is it legal?
In 2019, Washington became the first state to legalize human composting. As of July 2024, it's legal in 12 states. At least a dozen other states are working to pass legislation that would allow it to take place there.
What is the process?
First, to prepare your loved one for transformation, we gently wash and dress them in a biodegradable shroud. We also give your loved one an identification pendant, so there’s never any doubt whom we’re with.
Next, your loved one is placed on a layer of organic mulch and woodchip in a vessel designed especially for composting. Handpicked local wildflowers are scattered over the body before the vessel is sealed.
Then, with a little water, a little heat, and the careful balancing of carbon, nitrogen and oxygen, we create the perfect conditions for naturally occurring microorganisms to break down the body and gently transform it into soil.
What about the bones and teeth?
Bones and teeth don’t break down in the human composting process the way the rest of the body does. Instead, they are removed from the soil and reduced to a fine powder before being returned to the soil.
How long does human composting take?
The approximate time from when your loved one is placed in the vessel until soil is ready to be returned to you is 45 days.
How will the soil be returned to me?
The human composting process results in far too much soil for most families, approximately a half cubic yard. The majority choose to receive back only a small portion of their loved one’s soil. Most families take home one to five containers of soil.
Each recyclable, biodegradable, compostable container is 32 ounces and designed to store your loved one’s soil until you’re able to scatter or plant it. You may pick up the soil, one of our associates can deliver it to you, or we can send it to you by mail.
Should you wish to receive back all of your loved one’s soil—about 300 pounds—we can arrange for that as well.
What can my family do with the soil?
You may choose to place your loved one’s soil in a meaningful location. You may use it to nourish a favorite house plant, tree or flower garden. Any soil your family doesn’t take home will be spread on a reforestation site on the Olympic Peninsula. No matter what you choose to do, we recommend returning the soil to the earth within a couple of weeks of receipt.

How is human composting different from burial?
Burial refers to full-body interment in the ground. Some burials can be performed without a vault or embalming, and caskets can made entirely of organic materials. By contrast, human composting transforms a loved one’s body into soil indoors. The soil can then be returned to the earth.
Can I have a funeral or memorial if I choose human composting?
Absolutely. A celebration of life can take place before, immediately following or long after a loved one’s composting. The flexible timing means families don’t feel rushed to make plans immediately and faraway friends and relatives have time to travel.
We’re experts at creating personalized services for families of all backgrounds. To us, even small things matter—and capturing every detail creates an unforgettable send-off.
