Water Cremation vs Aqua Cremation: What is the Difference

What is Water Cremation?

Water cremation, also known as aquamation or alkaline hydrolysis, is an eco-friendly alternative to traditional cremation. This process utilizes a combination of water flow, temperature, and alkaline chemicals to accelerate the natural decomposition of the body, leaving behind only bone fragments. Unlike flame-based cremation, water cremation does not involve the release of carbon emissions.

Difference between Water Cremation and Aqua Cremation

While the terms “water cremation” and “aqua cremation” are often used interchangeably, it’s crucial to note that they refer to the same process. Both terms describe the use of water and alkaline chemicals to break down the body. In this context, there is no practical difference between the two.

Comparison Table: Water Cremation vs Aqua Cremation

Process of Water Cremation

Preparation

The body is respectfully placed in a stainless-steel chamber specially designed for water cremation. This chamber is then sealed to create a controlled environment for the process.

Chemical Solution

A mixture of water and alkaline chemicals, often potassium hydroxide, is introduced into the chamber. This alkaline solution is a key player in accelerating the natural decomposition of the body.

Temperature and Pressure

The chamber is heated to a specific temperature, usually ranging from 160 to 180 degrees Celsius (320 to 360 degrees Fahrenheit). The combination of heat and pressure within the chamber aids in the breakdown of organic matter.

Hydrolysis

Hydrolysis, the chemical reaction between the water and alkaline chemicals, begins to occur. This reaction effectively breaks down proteins, fats, and other soft tissues, leaving behind only the skeletal structure.

Completion and Filtration

The process typically takes several hours to complete. Once finished, the remaining solution is sterile and can be safely disposed of. The bone fragments, which are now clean and separated from any remaining tissues, are collected.

Ash Processing

The bone fragments undergo a further processing step to reduce them to a fine, ash-like consistency. These ashes, also known as cremated remains, are then returned to the family in an urn or another chosen vessel.

Process of Aqua Cremation

Placement in the Chamber

The deceased is respectfully placed in a specialized stainless-steel chamber designed for aqua cremation. This chamber is sealed to create a controlled environment for the process.

Introduction of Alkaline Solution

A mixture of water and alkaline chemicals, often potassium hydroxide, is introduced into the chamber. This alkaline solution is a critical component in facilitating the decomposition of organic matter.

Temperature Elevation

The chamber is heated to a specific temperature, typically ranging between 160 to 180 degrees Celsius (320 to 360 degrees Fahrenheit). The combination of heat and the alkaline solution accelerates the breakdown of tissues.

Hydrolysis Reaction

Hydrolysis, a chemical reaction between the water and alkaline chemicals, initiates. This reaction effectively dissolves soft tissues, breaking them down into simpler components.

Completion and Filtration

The aqua cremation process typically takes several hours to complete. Once finished, the remaining liquid is sterile and can be safely disposed of. The skeletal remains are left behind in the chamber.

Ash Processing

The bone fragments undergo further processing to reduce them to a fine, ash-like consistency. These ashes, also known as cremated remains, are collected and returned to the family in an urn or another chosen vessel.

Pros and Cons of Water Cremation

Pros of Water Cremation

• Environmentally Friendly: Water cremation has a significantly lower carbon footprint compared to traditional cremation, making it a more eco-friendly option.

• Reduced Energy Consumption: The process requires less energy than traditional cremation, contributing to overall energy conservation efforts.

• Minimal Air Emissions: Water cremation produces fewer air pollutants, making it a cleaner option in terms of atmospheric impact.

• Preservation of Bone Fragments: The skeletal remains following water cremation are well-preserved and can be processed into a dignified ash-like substance for memorialization.

Cons of Water Cremation

• Limited Legal Acceptance: Water cremation may not be legally accepted in all regions, limiting its availability as a choice for end-of-life disposition.

• Specialized Equipment Required: The process necessitates specialized equipment, which might not be readily available at all funeral homes, potentially limiting accessibility.

• Public Perception: Some individuals may be unfamiliar with or uneasy about the concept of water cremation, impacting its acceptance in certain communities.

Pros and Cons of Aqua Cremation

Pros of Aqua Cremation

• Environmental Sustainability: Aqua cremation has a significantly lower environmental impact compared to traditional cremation, contributing to a more sustainable and eco-friendly end-of-life option.

• Reduced Carbon Footprint: The process generates fewer carbon emissions, making it a cleaner alternative in terms of atmospheric impact.

• Energy Efficiency: Aqua cremation typically requires less energy than traditional cremation methods, aligning with broader efforts towards energy conservation.

• Preservation of Bone Fragments: The skeletal remains following aqua cremation are well-preserved and can be processed into a respectful and dignified ash-like substance.

Cons of Aqua Cremation

• Limited Legal Acceptance: Aqua cremation may not be legally accepted in all regions, limiting its availability as a choice for end-of-life disposition.

• Specialized Equipment Required: The process relies on specialized equipment, which may not be universally available at all funeral homes, potentially limiting accessibility.

• Public Perception: Some individuals may be unfamiliar with or uneasy about the concept of aqua cremation, potentially affecting its acceptance in certain communities.

• Availability and Cost: The availability of aqua cremation services can be limited, and costs may vary, making it less accessible for some individuals and families.
