This artificial reef is made of pet ashes. Human ashes are next
In June 2024, a team of divers sank a curious assortment of 24 sculptures off the northern coast of Bali. The sculptures look like works of art—and in many ways they are. But they are also memorial reefs that turn cremated ashes into structures that regenerate marine life.
Over the past three years, a British startup called Resting Reef has been working to revamp the death care industry. Instead of keeping ashes inside an urn (which often ends up gathering dust on a shelf) or scattering ashes at sea (a fleeting gesture that leaves no lasting trace), you can have Resting Reef integrate them into an underwater memorial that can double as an artificial reef.
Now, the results are in: Nearly a year after being placed on an otherwise barren stretch of seabed in Bali, the artificial reefs have attracted more than 46 new marine species. The site now boasts four times the fish biodiversity of the nearest comparable location thanks, in part, to the turf algae and coralline algae that have grown on the surface of the reefs, providing habitat for many marine organisms.
The Bali reef pilot, which was funded by six government grants from the U.K., is the only such reef in the world. (It consists of pets ashes, but reefs made with human ashes are coming next.) The team is also in conversations with sites in Plymouth, U.K., and in Mexico. 'Just as we have a cemetery around the corner, in the future we'll have memorial sites—marine sites—opening around the world,' says Aura Elena Murillo Pérez, who cofounded Resting Reefs with Louise Lenborg Skajem.
