Why Families Choose Biodegradable Urns for Sea Burials
The sea burial with an urn made of biodegradable materials gives that special parting touch, while also taking care of Mother Nature. Available eco-friendly materials that do not pollute the ocean or ecosystem are used to create the special ocean urns.
It is not every biogradable urn that is ocean-appropriate. Some are simply made for land burials. There are families that come to us with ocean-appropriate urns, which raises a different set of challenges. The receptionist… well, we are more than happy to help with any concerns that ensure a dignified and peaceful scattering at sea.
There is a wide variety of sea burial urns. The majority of which are designed to float up to a certain point before descending to the ocean floor. This gives family members enough time to utter their final words, toss in flowers and create a beautiful memory.
Most of our popular unique biodegradable urns and their uses, including instructional videos are presented below.
FAQ – Biodegradable Urns for the Ocean
What materials are biodegradable urns made from?
The biodegradable urns are crafted from paper, clay, salt, sand, and other biocomposite materials that are organic and eco-friendly. They get broken down in water and do not cause any pollution. All biodegradable urns are made in accordance with EPA standards since they dissolve in water.
How long do the biodegradable urns take to sink?
It depends on the type and the design of the urn. Certain urns, like the salt urns, sink instantly. These urns weigh about 20lbs without cremains and sink rapidly when placed in the water. Other urns like pillow-top or seashell urns sink down slowly and gently after floating, thus giving time for final tributes.
Do biodegradable urns come in different forms or colors?
Of course. They are offered in a variety of forms such as turtles, seashells, pillows, and simple spheres, and in different colors to match and honor the preferences and personality of the departed.
Can the urn be decorated before the ceremony?
Yes. We encourage families to write messages, attach flowers and leis, or otherwise personalize the urns before placing them in the water, thus making for a remarkably personal tribute. Some additional details are provided later on this page. We have a picture on our site of a family member holding a turtle urn that has messages written on it.
Are there urns big enough to hold the cremated remains of two persons?
Yes. Some urns, like the Seashell Biodegradable Urn, can often hold the cremains of two people, making them a perfect match for couples being scattered together.
Are there restrictions on carrying a biodegradable urn on a plane?
Most airlines permit carry-on and checked biodegradable urns, provided they comply with TSA screening rules (they generally do). Additionally, cremains in general should have a transit permit to transport the cremains. Your funeral home will be able to help you with this.
What’s the best way to select an urn for the family?
It depends on the budget, float time, preferred design, and whether you want the urn to sink right away or after a short ceremony. You are also welcome to speak with our team who can help you select the most suitable choice based on your needs.
Biodegradable Turtle Urn
Families bereaved often choose this biodegradable turtle urn for sea burials as it is our best seller. Made of eco-friendly materials, the turtle floats for a time then sinks beneath the ocean, providing families with a beautiful moment as the turtle disappears.
Before release, people can paint, decorate, or write messages on the turtle as a way to pay tribute and reminisce. Many families do the preparation and bring the turtle with them on the day of the charter. Some families add tradition and color by placing a fresh flower lei around the turtle’s shell.
Smaller “baby turtles” that hold a small portion of the ashes are optional for larger gatherings. Family members, say are 3 siblings releasing a parent, can release their own turtle as a group for a shared, meaningful farewell as the sun glitters on the open sea.

Flying with a Biodegradable Urn
Travelling with biodegradable urns does not generally pose any concerns, since they can be X-rayed. We do recommend that you take them as carry on luggage when they are already full with cremains. You do not want to take the chance of loosing them.
If urns cannot be x-rayed then you will have to take them as checked baggage. You should always check with the airline as rules can change.

How to fill and Use Biodegradable Urns
Water Soluable Bag
Each of these urns includes a water soluble bag inside it. It looks a bit like a plastic bag but will immediate designate when in contact with water, releasing the cremains into the ocean. The cremains are placed in this water soluble bad and then placed inside the biodegradable urn.

Placing a Biodegradable Urn in the Ocean
As a gesture of respect, each earn should be placed into the ocean by hand (if possible) and not dropped or thrown. On some vessels because of the height from the water a system with ropes may need to be devised to low the urn to the waters surface.
Dropping or throwing the urn may damage it and not allow it to float or perform as it was designed to do.
