Biodegradable Pet Urns for Green Burials or Keepsake

The Mycelia Collection – Grown to
Support New Life

Each urn in the Mycelia collection begins as a living organism. Over the course of several days, mushroom mycelium is carefully grown around bellflower fibers, gradually forming a solid, lightweight, and fully biodegradable vessel.

Unlike materials that are cut or extruded, mycelium grows into its final shape following a slow, gentle process that mirrors the natural cycle of rest and renewal. When buried, a Mycelia urn returns completely to the soil in approximately 45 days, actively enriching the earth and supporting new life.

For those who wish to honor their companion with a living memorial, or simply prefer a material that feels as organic as the bond they shared, the Mycelia collection offers something rare: a vessel that does not just hold ashes, but eventually becomes part of the earth again.

A Living Memory, Made Together

The soft, natural surface of these urns are ideal for personal expression. Before the ashes are placed inside, or even after, families and friends can write messages, draw small symbols, or add quiet decorations using non-toxic, biodegradable materials such as beeswax crayons or plant-based pens.

For children, this can be a gentle way to say goodbye and feel included. For adults, it is a quiet, intimate act of love. When the urn is buried, every mark returns to the earth along with it — a circle of memory and renewal.

Mycelium is Truly Circular and Natural

Not all biodegradable materials are suitable for burial

Many biodegradable urns are made from paper, untreated wood, or PLA (a plant‑based 3D‑printing filament). All of these are gentler on the planet than plastic or metal, but they work differently.

  • Paper urns break down over several months into soft, inert pulp.

  • Wood urns decompose slowly, depending on the thickness of the wood and soil conditions.

  • PLA urns are technically plant‑based, but most require industrial composting facilities — they are not reliably home‑compostable.

  • Mycelia urns are grown, not manufactured. Within roughly 45 days of burial, they fully reintegrate into the soil, actively nourishing it rather than simply breaking down into neutral residue.
