Possible Green Burial Option
This is an example of a biodegradable urn. A biodegradable urn is an urn that is capable of decaying through the action of living organisms. After being cremated, one can choose to be placed in such an urn in order to leave behind less material. This specific urn will use the nutrients in ashes to nurture a seed into a tree. All you have to do is pick which type of tree you want left as your memorial. This idea can be credited to Martín Azúa.
