When you think about what happens to our bodies after death, the traditional choices of burial or cremation likely come to mind. For centuries, these methods have been deeply woven into cultural, religious, and practical traditions.
But what if there was a third, environmentally friendly option that not only aligned with modern values but also addressed pressing climate concerns? Enter aquamation, a method that is reshaping the conversation around end-of-life choices.
Also known as alkaline hydrolysis or water cremation, aquamation offers a sustainable alternative by using water and an alkaline solution to decompose the body.
This process leaves only the skeleton, which is then turned into a fine white powder, much like the ashes produced by traditional cremation. But here’s the catch: aquamation uses 90% less energy than cremation and produces zero harmful emissions.
Aquamation in Action The process begins with placing the body in a pressurized vessel filled with a heated solution of water and potassium hydroxide.
Operating at temperatures between 200 and 300°F (90-150°C), this gentle method breaks down organic matter over several hours, leaving behind a sterile liquid byproduct and the skeletal remains.
The liquid, rich in nutrients, can be safely released into waterways or even used as fertilizer.
This eco-conscious method has garnered attention in recent years, particularly when South African Archbishop Desmond Tutu opted for aquamation in 2021.
Known for his humility and environmental advocacy, Tutu’s decision highlighted aquamation’s potential to align personal values with sustainable practices.
Challenging the Status Quo
For many, the idea of aquamation may seem unconventional or even unsettling. Burial and cremation have long been seen as the “natural” choices, and cultural norms often dictate end-of-life decisions. But these traditional methods come with significant environmental costs.
Consider burial: the process often involves embalming fluids, treated wood coffins, and concrete vaults, all of which have a lasting environmental impact. Burial grounds themselves consume vast amounts of land, and cemeteries often require maintenance that contributes to pollution.
On the other hand, cremation—while more space-efficient—releases harmful emissions, including carbon dioxide, mercury, and other toxins.
A single cremation emits an average of 534 pounds of CO2, equivalent to driving 600 miles in a car. In a world grappling with climate change, such practices demand reevaluation.
This is where aquamation stands apart. By challenging the assumption that burial and cremation are the only viable options, aquamation offers a contrarian yet compelling perspective: why not choose a method that honors the planet as much as it honors the individual?
The Science Behind Aquamation
The concept of alkaline hydrolysis isn’t entirely new. It has been used for decades in medical and veterinary settings to safely dispose of biological tissues. Its application for human remains, however, is relatively recent, gaining momentum as people seek greener alternatives.
The process works through a combination of heat, pressure, and an alkaline solution (usually potassium hydroxide or sodium hydroxide).
These conditions mimic the natural decomposition that occurs in soil but accelerate it to mere hours instead of years.
The remaining bones are dried and processed into a fine powder, which can be kept in an urn or scattered—just like traditional cremation remains.
The liquid byproduct, sometimes referred to as “effluent,” is sterile and nutrient-rich. Depending on local regulations, it can be safely released into wastewater systems or repurposed as an organic fertilizer for plants. This circular approach to death is a stark departure from the linear environmental impact of burial and cremation.
The Rising Popularity of Aquamation
Aquamation is slowly gaining traction worldwide, with legislative changes paving the way for broader adoption. In the United States, for example, over 20 states have legalized the practice.
Similarly, Canada, the UK, and parts of Europe are beginning to embrace this innovative method.
One reason for this rise in popularity is its alignment with shifting societal values. As more people prioritize environmental stewardship, the demand for sustainable end-of-life options has surged.
According to a 2022 survey by the Cremation Association of North America, 64% of respondents expressed interest in greener alternatives to traditional burial and cremation.
Additionally, aquamation is often more affordable than burial and comparable to cremation in cost, making it an attractive option for families seeking both environmental and financial sustainability.
Despite its benefits, aquamation isn’t without its challenges. Religious and cultural beliefs can influence how people perceive the method. Some may view the use of water as less “dignified” compared to fire or earth.
However, advocates argue that aquamation is deeply respectful, emphasizing its gentle, natural approach. Unlike cremation, which relies on intense flames, aquamation’s process mirrors the body’s natural decomposition—but in an accelerated and controlled environment.
There are also logistical hurdles to consider. Specialized equipment and facilities are required, which limits access in some regions. However, as demand grows, infrastructure is expected to expand, making aquamation more accessible to the general public.
A Greener Farewell
In an era where every choice—from the food we eat to the way we travel—is being reexamined through an environmental lens, end-of-life practices are no exception. Aquamation represents a significant step toward more sustainable living, even in death.
The decision to embrace aquamation is more than just an individual choice; it’s a statement about our collective responsibility to the planet. As awareness grows and cultural perceptions evolve, this innovative method has the potential to become a mainstream option for eco-conscious farewells.
So, the next time you think about end-of-life planning, consider this: could your final act be one that gives back to the Earth?
