Rethinking End of Life Traditions

For generations, families have faced only two main choices after death: traditional burial or fire cremation. But both carry hidden costs, not only for families, but for our communities and our planet. In life’s most tender moments, we search for choices that reflect our values, respect our loved ones, and care for the world we leave behind.

Water Cremation

How it Works

Aquamation (also known as alkaline hydrolysis or water cremation) is a respectful and eco-conscious way to return a life’s vessel back to nature. This gentle method mirrors the natural decomposition process that occurs when a body returns to the earth, but much more efficiently. By carefully combining water, mild alkalinity, heat, and sometimes pressure, aquamation accelerates how your body would naturally break down in soil, achieving in a few hours what might otherwise take months or even years.

Creating the Right Environment

The process takes place inside a sealed stainless‑steel chamber, where the body is placed in a warm, pressurized bath of water mixed with a mild alkaline solution. This controlled setting boosts the body’s natural return to the earth by encouraging molecular breakdown.

Breaking Down the Body with Care

Over 3 to 6 hours, depending on body mass and bone density, the combined action of heat, alkalinity, and pressure dissolves everything but the bones. Our team carefully oversees this process, and upon request, plays the music of your choice to honor your loved one.

What remains, and what’s returned

The bones, mostly mineral, are gently dried and processed into a smooth, white powder (not ash). The sterile liquid, called effluent, is rich in natural nutrients such as amino acids, peptides, salts, and sugars. This liquid contains no DNA or tissue and is returned safely to the earth. 

A Meaningful, Positive Outcome

Families receive the finely processed bone powder in an urn, offering a tangible way to remember a loved one. The nutrient-rich effluent supports ecological balance and continues to nourish the planet, becoming part of a cycle that promotes renewal and honors life’s continuity.

The Hidden Costs of Burial and Fire Cremation

1.5 Million Tons of Concrete Used Annually

Traditional burials consume 1.5 million tons of concrete and 30 million board feet of wood every year in the United States, along with embalming chemicals that seep into the earth. Cemeteries also occupy vast land.

534 Pounds of CO₂ Released per Fire Cremation

Each fire cremation emits about 534 pounds of CO₂, the same as driving a car roughly 600 miles. Multiply this by thousands of services each year, and the environmental footprint becomes staggering.

90% Less Energy Used with Water Cremation

Water cremation is one of the most energy-efficient end-of-life options available, with minimal emissions and zero mercury release. Each process uses only 150-250 gallons of water, which is filtered and safely returned to the environment, far less than what is needed to maintain traditional burial grounds.
