What Is a Biodegradable Urn and How Do They Work?

A biodegradable urn is an option after cremation for those who want to have less impact on the Earth and for some who find meaning in joining nature’s normal cycles of decay and rebirth.

According to the National Funeral Directors Association, more than 60 percent of those surveyed would consider a “green” option for funeral arrangements. Though the organization notes there are many “shades” of green depending on what matters to you (avoiding chemicals, saving land, not using carbon-producing methods), biodegradable materials in permanent memorialization options have increased in popularity as this trend continues.

Options for Biodegradable Urns

There are many options for choosing a biodegradable urn. They are made from many types of materials and have a range of prices. Among the choices are:

Clay, bark, or cast paper: Urns made from these materials break down in water without leaving dangerous residues.

Paper, fiber, or bamboo: Made from biodegradable materials, these urns are also buried, allowing “ashes” to return to the soil.

Rock salt urns: These are made with natural salt that dissolves in water or soil, so they are appropriate for either water-based or land-based dispersion.

Tree pods: Made from organic materials such as recycled paper or coconut husks. The pod is buried, and as it degrades, it provides nourishment for the tree seed to grow.

Wildflower paper urn: Like a tree pod, a wildflower paper urn will yield wildflower blooms as it decomposes, creating a natural memorial that is also safe for the environment.

According to the planning website Cake, urns made to resemble flowers, boats, balls, and shells also work well for water burials. However, the site warns that even biodegradable items may have an environmental impact, so be sure to be aware of the rules around their use.

Be Aware of Scattering Rules

If you are planning a water burial, you will want to be aware of the Environmental Protection Agency rules:

• You must scatter ashes three nautical miles from land or more.
• You may only use biodegradable urns that don’t harm the marine environment.
• If flowers or wreaths are also used, these must also be biodegradable.
• The burial must be reported to the EPA within 30 days.
• This does not apply to pet ashes unless a special permit is acquired.

Whether you plan to scatter or bury on land or sea, a good rule of thumb is to always ask the landowner and to check local laws. You can find more tips on scattering cremated remains here.

DIY Biodegradable Urns

According to Cake, there are several ways you can create your own do-it-yourself biodegradable urn.

1. Water Soluble Bag: If you plan to disperse the remains in water, a water-soluble bag will work. Available in blue and clear, these options may not be the most visually striking on their own, but they offer a wonderful opportunity for customization and decoration to enhance their aesthetic appeal.
2. Paper or Compostable Bag: Again, these bags can be decorated to make them more aesthetically pleasing, but work well for those who want to add remains to a garden or backyard setting.
3. Paper Mache: A paper mache urn can be used for land or sea. If you plan to have it biodegradable, make sure you use only safe materials.
4. Seedling Pot: Mix the remains with ashes and seeds and store in the home until ready to use in the garden.
5. Tree Urn: Similar to the seedling pot, the tree urn can combine ashes with soil and a seed or seedling for a tree, symbolizing the rebirth that is a part of nature’s cycle.

It’s important to remember that cremated remains will not break down like compost because they contain calcium and are more similar to rock. However, with additional soil amendments, they can be scattered in gardens without harming plants.

Do Your Homework on Biodegradable Urns

Not all biodegradable urns are appropriate for every area. Check the materials to ensure their safety in water or soil, and make sure you follow the scattering rules for the area you choose.

With the right biodegradable urn in the right location, you can affordably and meaningfully send off a loved one with a beautiful, environmentally conscious tribute.
