In recent years, there has been a growing interest in alternative methods of handling human remains that are more environmentally friendly than traditional burial and cremation. One such method gaining popularity is aquamation, also known as alkaline hydrolysis or water cremation. This innovative process offers a more sustainable and gentle approach to the disposition of human remains. In this guide, we'll explore what aquamation is and how it differs from traditional cremation.
Understanding aquamation
Aquamation (also known as resomation) is a water-based method of disposition that uses a combination of water flow, temperature, and alkalinity to accelerate the natural process of tissue hydrolysis. Unlike flame-based cremation, aquamation relies on a chemical reaction to break down the body into its basic components. The process takes place in a specialised chamber known as an alkaline hydrolysis unit.
The aquamation process
1. Preparation
The body is prepared in a manner similar to traditional cremation. It is placed in a suitable container and then loaded into the aquamation chamber.
2. Alkaline hydrolysis
The chamber is filled with a combination of water and an alkaline solution, typically potassium hydroxide. The temperature is elevated to accelerate the breakdown of the body. The chemical reaction softens the tissues, dissolving organic matter while leaving behind bones.
3. Separation
After the hydrolysis is complete, the remaining bones are easily separated from the liquid solution. The bones are then processed into a fine powder similar to traditional cremated remains.
4. Neutralisation
The liquid byproduct, which consists of amino acids, peptides, and salts, is safe to be released into the municipal water treatment system. The process is environmentally friendly, as the chemicals used are mild and the quantity of water required is minimal compared to other methods.
Advantages of aquamation
- Environmental sustainability - Aquamation has a significantly lower carbon footprint compared to traditional cremation. It uses less energy and does not emit harmful gases into the atmosphere.
- Gentler process - The process is less traumatic to the environment and the body. It is considered a gentler option, as it mimics the natural process of decomposition in a more controlled and accelerated manner.
- Reduced mercury emissions - Traditional cremation releases mercury into the atmosphere from dental amalgam fillings. Aquamation eliminates this concern, making it a safer option for the environment.
- Preservation of bones - The bones remaining after aquamation are often more easily crushable into a finer powder than those from flame-based cremation. This can be a comfort to those who choose to keep the cremated remains as a memorial.
Considerations and legal status
While aquamation is gaining acceptance, water cremation is legal in the UK, subject to compliance with health, safety and environmental regulation. However, it is still important to check with local authorities and consult with funeral professionals to ensure compliance.
Aquamation offers a compelling alternative to traditional cremation, providing a more eco-friendly and gentle method of handling human remains. As awareness of environmental impact grows, this innovative approach is likely to become more widely accepted. For those considering end-of-life options, exploring aquamation as a choice aligning with personal values and environmental consciousness is increasingly becoming a viable and compassionate choice.
