Biodegradable Urns for Burial at Sea
Biodegradable urns offer a gentle, environmentally respectful way to return a loved one to the ocean. Made from natural materials such as recycled paper, salt, sand, or gelatin, these urns are designed to dissolve naturally after entering the water—leaving no lasting impact on the marine environment.
Not all biodegradable urns are suitable for burial at sea, however. Some products marketed as “biodegradable” are intended for ground burial only. Our team carefully reviews each urn to ensure it meets California ocean burial requirements and performs as intended during a sea ceremony.
We regularly use and stock approved biodegradable urns on our charters and are always happy to guide families in selecting an appropriate option.
California Requirements for Sea Burial
-
- Be fully biodegradable
- Break down completely within four hours
- Contain no metal, plastic, or synthetic components
A Disposition of Human Remains Permit is required for all burial-at-sea ceremonies in California. This permit must be issued and available before the vessel can legally depart the dock. To learn how the permit works, who can obtain it, and how we help families handle this step, visit our Disposition of Human Remains Permit page.
Unfortunately, families are sometimes told an urn is ocean-approved when it is not. We help prevent this by reviewing urns in advance and offering approved alternatives when needed.
How Biodegradable Urns Work
All biodegradable urns include a biodegradable inner bag. The cremated remains are first placed into this bag, which is then secured inside the urn.
-
- The urn may float briefly depending on design and water conditions
- Once submerged, the inner bag dissolves immediately
- The urn then breaks down naturally, releasing the cremains gently into the ocean
Urns are not required for ash scattering, but some families prefer them to:
-
- Reduce wind or blow-back
- Align with religious or cultural traditions
- Create a symbolic, contained farewell
Frequently Asked Questions About Biodegradable Urns
Are biodegradable urns required for burial at sea?
Biodegradable urns are not required for ash scattering at sea when cremated remains are released directly into the water. However, a biodegradable urn is required if an urn will be placed into the ocean as part of a burial at sea ceremony.
California regulations require that any urn entering the water be fully biodegradable and designed to break down naturally within a short period of time. Urns made for ground burial may be labeled “biodegradable” but are often not suitable for ocean use.
Many families choose biodegradable urns because they help contain the cremated remains during the ceremony, reduce wind or blow-back, and align with environmental, religious, or cultural preferences. Our team reviews all urns in advance to ensure they are appropriate and compliant for burial at sea.
Can families bring their own biodegradable urn?
Yes. Families are welcome to bring their own biodegradable urn for a burial at sea, provided it meets California ocean burial requirements. The urn must be fully biodegradable, contain no metal or plastic components, and be designed to break down naturally in water within the required timeframe.
Because some urns marketed as “biodegradable” are intended only for ground burial, we recommend having the urn reviewed in advance. Our team is happy to confirm whether a specific urn is appropriate for ocean use and suggest alternatives if needed.
How long do biodegradable urns float before sinking?
Float time varies depending on the type of urn, ocean conditions, and the weight of the cremated remains. Some biodegradable urns float briefly, allowing families a moment of reflection, while others may bob gently before slowly sinking.
Once submerged, the urn and inner biodegradable bag begin breaking down naturally, releasing the cremated remains into the ocean in a respectful and environmentally responsible way.

🐢 Biodegradable Sea Turtle Urn
The biodegradable sea turtle urn is lovingly handcrafted from recycled paper using non-toxic, eco-friendly adhesives. Each urn is individually made by skilled artisans, meaning no two turtles are exactly alike—subtle differences in size, shape, and color reflect the uniqueness of the life being honored.
Symbolically, the turtle represents longevity, protection, and safe passage, making it a meaningful choice for ocean ceremonies. When placed in the water, the turtle typically floats for a short time before slowly taking on water and gently sinking beneath the surface. Float time varies based on sea conditions and the weight of the cremated remains.
Once submerged, the urn biodegrades naturally over time, leaving no trace in the marine environment. Smaller “baby turtle” urns are also available and are often chosen by families who wish to participate together in the ceremony by sharing the scattering experience.
🧂 Himalayan Salt Urn
Himalayan salt urns are individually hand-carved from solid blocks of natural rock salt formed over 250 million years ago, making each urn a one-of-a-kind piece of natural art. Variations in color, texture, and mineral pattern ensure no two urns are ever the same.
These urns create a striking and dignified presence during a burial at sea ceremony. Once placed into the ocean, the salt begins to dissolve immediately and typically breaks down completely within approximately four hours, in full compliance with California sea burial regulations.
Each salt urn includes a biodegradable inner bag and tie for the cremated remains, ensuring respectful containment until the moment of release. Families often choose salt urns for their strong symbolism—representing purification, impermanence, and a return to the elements.
🛏️ Journey (Pillow-Style) Urns
Journey urns are hand-crafted from sustainably sourced, biodegradable paper and are designed with a soft, pillow-like shape. A distinctive footprint motif represents the journey of life and the path taken by the loved one being honored.
When placed in the ocean, Journey urns typically float briefly, allowing families a quiet moment of reflection before the urn slowly sinks and naturally biodegrades over time. These urns are available in a variety of calming colors, including ocean blue, dark blue, white, gray, and green.
Because of their balanced design and predictable behavior in the water, Journey urns are a popular choice for families who want a serene and visually gentle farewell. Video of a biodegradable journey urn on our urn video page.
🏖️ Biodegradable Sand Urns
Sand urns are made from natural sand combined with biodegradable binding agents, giving them a solid, stone-like appearance while remaining environmentally responsible. When placed in the ocean, they briefly bob on the surface before descending to the seafloor.
Over time, the urn gradually breaks down and returns to its natural state. Sand urns are available in multiple sizes; we generally recommend the larger size to comfortably accommodate all cremated remains and ensure proper fit.
Families often select sand urns for their simplicity and grounding symbolism—representing earth, stability, and the natural cycle of life.
🐋 Biodegradable Whale Urn
Biodegradable whale urns are handcrafted from environmentally friendly materials, including recycled paper, using the same careful process as the turtle urns. Designed to hold a standard amount of cremated remains, these urns float briefly before gently sinking below the surface.
Whales symbolize strength, guidance, and deep connection to the ocean, making this urn especially meaningful for those who loved the sea or marine life. The whale urn provides a visually powerful yet peaceful tribute, offering comfort to families seeking a symbolic ocean farewell.
🐚 Seashell Biodegradable Urns
Seashell urns are made from recycled paper products and are available in soft coastal tones such as blue, sand, pearl, and coral. Their curved, shell-inspired design gives them a delicate and comforting appearance during the ceremony.
A unique feature of seashell urns is the availability of matching keepsake urns, allowing families to retain a small portion of the cremated remains as a personal memorial. These urns tend to float longer than some other biodegradable options before gently sinking and biodegrading naturally over time.
Seashell urns are often chosen for their symbolism of home, protection, and remembrance.
Traveling With Biodegradable Urns
Traveling with a biodegradable urn is generally straightforward. We recommend carrying the urn as carry-on luggage once it contains cremated remains, as this reduces the risk of loss or damage.
TSA must be able to screen the contents using x-ray. If the interior cannot be clearly viewed, the urn may need to be placed in checked baggage. Because airline and security policies can change, we always recommend confirming current requirements with your airline before traveling.
