“Bio urns” specifically refer to biodegradable urns designed to grow a living memorial, typically a tree, from cremated remains. They represent a unique and increasingly popular option for those seeking an environmentally friendly and symbolic way to honor a loved one. Here’s a breakdown of what they are:
Key Features:
Living Memorials:
The core concept is to transform cremated remains into a living tree or plant, creating a lasting and growing tribute.
Biodegradable Materials:
Bio urns are made from materials that decompose naturally, allowing the ashes to integrate with the soil. For Tree Urn, we selected cork for its exceptional natural properties. Discover the properties of cork here
Integration of Ashes and Growth:
They are designed to facilitate the germination and growth of a sapling, with the ashes providing nutrients to the developing tree.
Ecological Focus:
Bio urns align with the growing trend of green burials and eco-conscious end-of-life practices.
How They Work:
Typically, a bio urn has two main compartments: one for the cremated remains and another for a sapling.
The design allows the plant’s roots to gradually interact with the ashes as it grows.
The biodegradable materials of the urn break down over time, leaving only the living tree or plant.

Popularity and Benefits:
Environmental Responsibility:
They offer a sustainable alternative to traditional burial methods.
Symbolic Meaning:
The growth of a tree symbolizes the continuation of life and provides a tangible, living memorial.
Personalization:
Families can choose the type of tree or plant that holds special significance. Refer to our tree symbolism page here
Where to burry the bio urns:
When considering a biological urn, it is important to learn about local specific regulations.
Here you will find some of them
| Aspect | Biodegradable urns | Conventional burial container | Scattering ashes |
|---|---|---|---|
| Material end-of-life | Breaks down in soil | Remains intact long-term | No container |
| Ritual format | Planting-oriented or simple outdoor rites | Formal gravesite | Flexible, location-dependent |
| Upkeep | Minimal to none | Plot maintenance varies | None |
| Rules | Location-specific | Cemetery rules | Location-specific |
Glossary
-
Biodegradable urn: an urn designed to break down naturally in soil.
-
Compostable (industrial/home): requires defined conditions to decompose; may not equal biodegradation in all soils.
-
Bio-based: made partly from biological resources; not the same as biodegradable.
-
Green burial: broader set of practices minimizing environmental impact.
FAQ
1) What does “bio urn” mean in this article?
It is shorthand for biodegradable urn, a generic category of urns designed to naturally break down in the soil.
2) How long does a biodegradable urn take to break down?
Timelines vary by material and conditions—from months to several years. Some materials (e.g., cork) may take about 6–8 years in typical soils.
3) Can ashes affect young roots?
Cremation ashes are alkaline and saline. Many designs add a buffer layer or staged contact so early roots aren’t stressed.
4) Which tree type should we choose?
Prefer native or climate-adapted species suited to light, soil, and space at the site. Seedlings are generally more predictable than seeds.
