Resting Reef turns a loved one’s loss into a memorial reef designed to restore marine biodiversity.
Jun 12, 2025
They use aquamation, an alkaline process for cremation, and combine a pet’s remains with crushed oyster shells and concrete, which is then molded into reef structures in which fish species can thrive.
Once a reef is ready, it’s anchored about 10 meters down into a seabed, where it will improve marine biodiversity, filter water, and prevent coastal erosion.
“Cemeteries should be places that reconnect us with nature and remind us that we’re part of a larger ecosystem,” Murillo Pérez told The Guardian. “It’s time for the death industry to change: we want to shift the industry from focusing on death to life and regenerate growth.”
Meaningful in its desire to reconnect earthly beings with the earth itself, the process also has a real impact on marine environments.
The startup began placing the pilot reefs in Bali, Indonesia last year. In their first project, they placed 24 memorial reefs for pet owners in the United States and U.K.
After tracking its progress, they found that it attracted 84 fish species and achieved fish diversity “14 times greater than nearby degraded areas.”
“In just six months, the reefs are already covered with coralline and turf algae, laying the groundwork for future coral growth,” Resting Reef added in a social media post.
Part of the success comes from the materials mixed with the ashes: Oyster shells.
“Oyster reefs can help regenerate marine growth but 85% have been lost due to human activities,” Murillo Pérez explained. “We are using animal and human ashes to mimic those natural reefs.”
While all human ashes vary, most will primarily be made up of calcium phosphate, which Skajem said is “one of nature’s main fertilizers.”
When used as part of the Resting Reef materials, this calcium phosphate helps various species attach to the surface of the artificial reef and grow.
With this pilot under their belt, the founders say demand has been so great that Resting Reef is now opening up their process to human remains. Right now, they are working to secure licenses to restore degraded seabeds on the southern coast of England.
“Just as we have a cemetery around the corner, in the future we’ll have memorial sites — marine sites — opening around the world,” Murillo Pérez told Fast Company.
It’s part of a growing trend toward “green burials,” with innovations like mushroom coffins and tree burial pods aiming to reduce the carbon footprint of traditional burials. The green burial industry is expected to surpass $1 billion by the end of 2030.
Traditional cremation releases an average of 500 pounds of carbon dioxide per person. In this case, however, Resting Reef’s aquamation process has a far smaller carbon footprint, with its end result going right back into the ocean, which has been shown to store carbon even better than trees.
Resting Reef currently offers two separate designs: A ribbed-textured reef structure ideal for species like oysters, and one full of crevices and tunnels similar to coral reefs for fish species.
Prices start at £350 (or about $475 USD), and can go up to £2,250 (about $3,050 USD), depending on how private and customizable customers would like to get. The company’s website also notes that these are “early-bird” prices.
According to The Guardian, human memorials have an initial cost of £3,900 ($5,300 USD).
For many, it’s hard to put a price on the comfort of knowing a loved one — furry or otherwise — has been sent off in peace and with purpose.
“It makes it easier for me knowing that his ashes will be doing a really good thing,” Lisa C., a horse owner who utilized the service, said in a testimonial.
Resting Reef also offers a private ceremony either before or after the memorial reef is placed underwater, allowing loved ones to process grief, find closure, and connect with loved ones. Their team leads a guided meditation and nature-related rituals and invites participants to share memories, if they feel compelled to do so.
“I’ve learned that grief and renewal are deeply connected — not just emotionally, but in a tangible, environmental way,” an anonymous testimonial states.
“I’ve seen how loss can transform into something life-giving, how traditions and rituals provide comfort and meaning, and how true impact happens when a project is built with heart, respect, and community.”
You can find the Prompts podcast here, I drew some of the covers :D Also check out this digital library full of Creative Commons Solarpunk art (neither of these are sponsored).
🦗Somewhat shameful plug🦗
I would highly appreciate if you threw me a couple bucks on Buy Me a Coffee or bought a commission, my money number is only getting smaller these days 😔🤙
I’m watching Splash (1984) which is a romcom about a guy who falls in love with a mermaid, and when she chooses a human name she chooses Madison and guy says “that’s not a real name, but alright” which seems to imply that Madison was not a name until at least the 80’s and all girls named Madison are actually named after the mermaid. thought you should know
something has gone deeply wrong when "focusing pragmatically on issues you can influence and working to make life better for yourself and your community" is considered an unserious distraction while "endlessly exposing yourself to media about distressing situations you can't control" is considered political engagement
You know, I really despise that both Microsoft and Apple forcibly downloaded their AI "companions" onto my computer/iPad without my permission.
I didn't even authorize an update download. I woke up and they had both just...done it.
I don't really care if these AI programs are fantastic. The point is that they were installed without my knowledge or consent. And I don't want them.
Copilot was easy enough to uninstall on my desktop. I haven't found a way to get Apple Intelligence off my iPad, though I'm sure there is a way to do it. I did disable as many system permissions and features for it as possible, though.
I know this isn't anything new and has been a problem with tech companies for a while. I'm just extremely annoyed by this sense of entitlement and the assumption that they know best for us. If I wanted AI, I'd get AI. If I really wanted it, I'd even pay for it. But I don't want it, and I don't care if it's free. Don't step over my choice in this.
