- Production Technology
- This urn is made from ECOSHELL, a biodegradable material created by blending finely crushed oyster shells into a biomass-based resin. Its lid and base are joined with a precisely engineered screw thread, ensuring the contents remain secure even if the urn is tipped over, an advantage over conventional urns. A small charm, crafted from an alloy of silver, copper, and gold, remains with the owner as a keepsake. The urn itself has a warm matte texture and soft contours, inviting touch, fostering new rituals, and easing the pain of loss.
- Design Challenge
- The main challenge was designing an urn that fosters emotional healing while redefining traditional perceptions of memorialization. We overcame difficulties in translating intangible emotions into tangible design features, integrating Japanese home memorial traditions with natural burial practices. External limits included sourcing and molding a biodegradable yet durable material, and ensuring a secure screw-top structure without sacrificing warmth and tactility.
- Project Duration
- The project commenced in October 2022 in Hiroshima, Japan, where planning and development took place, and the design was completed in June 2023. Released in March 2025, it continues to be available.
- Operation Flow
- After cremation, the pet’s ashes are placed into the urn and taken home. It can be kept nearby for home memorialization, with the charm attached as a daily reminder. Owners can hold, stroke, or speak to it as they would in life, offering comfort and time for grieving. When ready, the ashes and urn can be buried to return to nature, while the charm is removed and kept close as a lasting keepsake.
- Research
- This qualitative design research identified a lack of meaningful mourning rituals for bereaved pet owners. Through literature review, cultural analysis, and interviews, we examined emotional changes, recovery processes, and posthumous communication with pets. Insights informed the form, structure, and materials, designing not only a physical urn but also a process that naturally supports emotional healing through use.
- Inspiration
- The design was inspired by the emotional gap many pet owners face after loss: the absence of meaningful mourning rituals. Drawing on Japanese customs of keeping ashes at home and the emerging practice of natural burials, it enables a continuous, personal farewell from collection to burial. Insights from grief care research and dialogues with bereaved owners shaped the structure, materials, and tactile qualities, offering a nature-connected and emotionally supportive alternative to traditional urns.
