Terramation Soil Return: Urns and Containers (colloquially referred to as human composting)

After the natural organic reduction (NOR) process is complete, families receive approximately one-half cubic yard of soil — that has been transformed from their loved one’s remains along with organic plant material. This soil is the tangible result of terramation, and what families choose to do with it is one of the most personally meaningful parts of the experience. This article covers what container options are available, how the soil is typically delivered, and practical guidance for families deciding how to store, use, or share it.

What do you receive back after terramation, and what can you do with it?

Families receive approximately one-half cubic yard of Regenerative Living Soil — a biologically active, nutrient-rich organic material meaningfully different from cremation ash. This volume is roughly equivalent to a large wheelbarrow load and is enough to support a memorial tree planting, enrich a garden bed, be divided among multiple family members, or donated in whole or part to a conservation organization. Providers offer container options including biodegradable bags, wooden boxes, and natural fiber sacks suited to different uses and storage needs.

  • Families receive approximately one-half cubic yard of biologically active soil — significantly more than the 2–8 lbs of cremated remains returned after cremation.
  • NOR soil is functionally similar to premium compost — it improves soil health and nourishes plant life, unlike cremation ash which is primarily inert calcium phosphate.
  • Container options typically include biodegradable kraft paper bags, wooden boxes, and natural fiber sacks; breathable containers are preferred for long-term home storage.
  • Airtight sealed containers are not ideal for long-term storage of NOR soil — they can cause moisture buildup and degrade the biologically active material over time.
  • Families can split the soil among multiple family members and uses — a portion to a memorial tree, another to a conservation donation, and a smaller portion kept at home.
  • Planning what to do with the soil before the process completes makes the return feel purposeful — ask your provider about container options, volume division, and transport logistics in advance.

What Is the Soil That Comes Back After Terramation?

The soil returned to families is the result of the complete natural organic reduction process — a rich, dark, nutrient-dense organic material that has genuinely positive effects on plant and soil health. TerraCare Partners calls this product Regenerative Living Soil™ — a name that reflects what the material actually is: biologically active, beneficial soil, not inert ash.

Other providers use their own names for the soil return. Whatever the provider calls it, the material is functionally similar: a finished organic soil amendment produced from human remains and plant-based co-composting materials.

This is meaningfully different from cremation ash (cremated remains), which is primarily calcium phosphate — inert, mineral-based, and not particularly beneficial to plant growth on its own. The terramation soil is biologically active and genuinely nourishing to plant life.

How Much Soil Will a Family Receive?

Approximately one-half cubic yard. This is a substantial volume, significantly more than the two to eight pounds of cremated remains typically returned after cremation.

For families accustomed to thinking of remains in the context of a small urn, the quantity of terramation soil can come as a surprise. One-half cubic yard is about the volume of a large wheelbarrow load. It is enough to meaningfully enrich a garden bed, support the planting of a large tree, or be divided among multiple family members for separate uses.

Planning what to do with this volume of soil before the process completes is genuinely useful — not because the decision needs to be made immediately, but because having a clear intention makes the soil return feel purposeful rather than logistically uncertain.

What Container Options Do Providers Typically Offer?

Container options vary by provider, but most offer several choices:

Biodegradable bags. A common option — heavy-duty kraft paper or natural fiber bags that allow the soil to breathe and are themselves compostable. Well-suited for families who plan to use the soil in the ground relatively soon.

Wooden boxes or crates. Some providers offer simple wooden containers for families who want a more ceremonially dignified presentation. Natural, untreated wood allows some airflow while providing a meaningful physical form for the soil return.

Natural fiber sacks. Burlap or cotton sacks are another breathable option. Sturdy for transport and appropriate for families who want to scatter or plant in multiple locations.

Custom containers. Some providers can accommodate custom or family-supplied containers — check with your specific provider about their policies.

The right container choice depends on what you plan to do with the soil and how soon. Families who intend to use the soil outdoors within weeks or months have more flexibility. Families who plan to store some soil at home for longer periods should think more carefully about container choice.

What Containers Are Not Ideal for Long-Term Storage?

Fully airtight, sealed containers — like tightly lidded plastic bins or sealed metal containers — are not ideal for long-term terramation soil storage. Soil is a biologically active material, and it benefits from some airflow. A completely sealed container can cause moisture buildup and degrade the soil over time.

Thin plastic bags, while convenient, are not recommended for long-term storage either — they don’t breathe well, they can puncture easily, and they are not consistent with the natural ethos most families choosing terramation hold.

If you’re storing soil at home for an extended period, a breathable container — ceramic or clay pots with drainage holes, natural fiber bags within a wooden box, or ventilated wooden containers — kept in a cool, dry place is preferable. Think of it similarly to storing garden soil: airflow and moderate conditions preserve its quality.

Can Families Split the Soil Among Multiple People?

Yes, and this is common. Because the volume is substantial — many families choose to divide the soil for different uses or different family members. Some families:

  • Plant one portion under a tree in a family member’s yard
  • Send a portion to a grandchild or close friend who lives elsewhere
  • Donate part of the soil to a conservation project
  • Keep a smaller portion at home in a meaningful container
  • Use part of the soil in a memorial garden

There is no regulatory barrier to splitting the soil — it is treated as the family’s to use in the ways they choose, subject to state-specific rules about where human remains (including NOR soil) may be scattered or distributed. Providers can advise on state-specific requirements.

What Are the Most Meaningful Things Families Do with the Soil?

Tree planting. Planting a tree over or with the soil is one of the most popular choices. It creates a living memorial that grows over years and decades. Many families choose a tree species that was meaningful to their loved one — a fruit tree, a native oak, a flowering cherry.

Scatter in a natural area. Families may choose to scatter soil in a forest, meadow, or other meaningful natural space. Check state and local regulations for scattering on public land — see the state guides for state-specific NOR soil disposition rules.

Donate to conservation. Some families donate all or part of the soil to a land trust, reforestation project, or conservation organization. Some NOR providers have partnered with conservation land in Washington, where families can choose to have their soil contribute directly to forest restoration. This option is described in more detail in our article on donating NOR soil to conservation projects.

Memorial garden. Some cemeteries and memorial parks are developing terramation garden sections — designated areas where families can use NOR soil and return to visit. This hybrid model combines the ecological benefit of terramation with the continued-access aspect of traditional cemetery burial.

Keep at home. Some families keep a portion of the soil in a meaningful container — a favorite pot, a handmade ceramic vessel — as a tangible presence in their home or garden.

What Practical Planning Steps Should Families Take Before Soil Return?

A few things worth thinking about before the process is complete:

Decide on primary use before you receive the soil. You don’t need every detail worked out, but having a main intention — “we’re planting a tree in mom’s garden” — makes the soil return feel purposeful and logistically clear.

Tell family members in advance. If multiple family members want a portion of the soil, the provider can help facilitate division at the time of soil return rather than requiring families to manage the process themselves.

Ask your provider what containers they use. Provider policies vary. Some include a specific container in their fee; others offer options for purchase; others let you supply your own. Know this before the return date.

Think about transport if you’re traveling. One-half cubic yard of soil is heavy and bulky. If family members are traveling to receive or scatter the soil, logistics matter. Providers can often arrange phased returns or hold portions for family pickup over a period of time.

How much soil is returned after terramation?

Approximately one-half cubic yard. This is significantly more than the remains returned after cremation, and enough to meaningfully support a memorial tree planting, a garden, or be divided among multiple family members.

Can I use a regular urn for terramation soil?

A traditional cremation urn is too small for the full volume of NOR soil (about one-half cubic yard compared to 2–8 lbs for cremated remains). If a family wants to keep a smaller portion of soil at home in an urn-like vessel, that’s possible — but the full return requires something closer to a large wooden box, a substantial natural fiber bag, or a similar container.

Can I split the terramation soil among family members?

Yes. Many families choose to split the soil for multiple uses — planting in different locations, sharing among family members, or combining personal use with a conservation donation. Providers can help facilitate the division at soil return.

Is terramation soil safe to handle and use in a garden?

Yes. The NOR process is designed to eliminate pathogens through sustained temperatures, turning, and time. The resulting soil meets safety standards and is safe to handle, use in gardens, and donate to conservation projects. Providers follow state regulatory guidelines for their soil return processes.

What container should I use for long-term home storage of terramation soil?

Use a breathable container — natural fiber, untreated wood, or a ventilated ceramic vessel — stored in a cool, dry place. Avoid fully sealed airtight containers, which can cause moisture buildup. Think of it similarly to storing quality garden soil.
