Scotland Legalises Water Cremation: First UK Nation to Approve Alkaline Hydrolysis

Scotland has become the first country in the United Kingdom to legalize water cremation, also known as alkaline hydrolysis. This decision introduces a third funeral option alongside burial and traditional cremation. The change has been described as the biggest reform in cremation law since cremation was introduced in 1902. The Scottish government expects the first water cremations to take place by summer 2026. Once specialized equipment receives planning and regulatory approvals.

What Is Water Cremation or Alkaline Hydrolysis?

Water cremation, scientifically known as alkaline hydrolysis, is often described as a “green cremation” due to its lower environmental impact.

How the Process Works

• The body is wrapped in a biodegradable shroud (silk or wool).
• It is placed inside a sealed, pressurized stainless steel chamber.
• The chamber is filled with water and potassium hydroxide.
• Heated to 150°C (300°F) for about 90 minutes.
• Soft tissue dissolves, leaving only bones.
• Bones are dried, processed and returned to families as powdered remains, similar to ashes.

The equipment used includes systems like the Resomator S750, manufactured in the UK by Kindly Earth.

Why Is Water Cremation Considered Environmentally Friendly?

Traditional cremation emits approximately 320 kg of carbon dioxide per procedure. Studies suggest alkaline hydrolysis produces seven times less CO₂ emissions.

Key environmental benefits include,

• Lower carbon footprint
• Reduced air pollution
• No direct flame combustion
• Energy efficient system

The method has already been adopted in countries such as the United States and the Republic of Ireland. Notably, anti-apartheid leader Desmond Tutu chose alkaline hydrolysis for his funeral.

Government and Industry Response

Scotland’s Public Health Minister Jenni Minto described water cremation as an “environmentally friendly alternative” to traditional methods. She assured that the process will be regulated with the same safeguards applied to burial and flame cremation, ensuring dignity and respect.

Before operations begin, hydrolysis facilities must,

• Secure planning permission
• Obtain approval from Scottish Water
• Meet existing funeral regulatory standards

Funeral directors have welcomed the change, stating it provides families with greater choice. Industry representatives say pricing will likely be similar to, or slightly above, traditional cremation costs.

A Shift in Funeral Choices in the UK

• The introduction of alkaline hydrolysis reflects growing public interest in sustainable end of life options.
• While it is not expected to replace traditional cremation entirely, it expands options for individuals seeking eco friendly funerals.
• Funeral professionals report that some people have already included water cremation in their future funeral plans.
• And also highlighting a shift toward personalized and environmentally conscious decisions.
