Scotland has become the first nation in the UK to legalize alkaline hydrolysis, commonly referred to as water cremation, as an end-of-life care option. This significant development allows families to choose this environmentally friendly alternative alongside traditional burial and cremation methods. Water cremation is already permitted in the Republic of Ireland and many states in the United States.
The process of alkaline hydrolysis involves placing the body in a pressurized chamber filled with hot water and potassium hydroxide. The chamber is heated to approximately 150 degrees Celsius (300 degrees Fahrenheit) for up to 90 minutes, breaking down soft tissue while leaving behind the bones. After rinsing the remains at 120 degrees Celsius (248 degrees Fahrenheit) and drying them, the bones are pulverized into a coarse powder, similar to ashes from traditional cremation.
One of the compelling features of water cremation is its reduced environmental impact. A standard cremation emits around 320 kilograms (705 pounds) of carbon dioxide, whereas alkaline hydrolysis produces seven times less CO2. This considerable reduction may appeal to families considering their environmental footprint during end-of-life planning.
Before the first water cremations can take place in Scotland, the necessary hydrolysis equipment must be manufactured, approved, and installed. The Scottish government anticipates that these procedures could begin as early as this summer. Kindly Earth, which has exclusive rights to produce the equipment in the UK, has been in discussions with various Scottish organizations to facilitate this rollout.
This policy shift is noteworthy not only for its environmental implications but also for the broader choice it offers families during a deeply personal time. Scotland’s implementation of water cremation may set a precedent for similar options in England, Wales, and Northern Ireland, where families currently only have access to burial or flame cremation. The reception and uptake of water cremation in Scotland could influence future decisions regarding end-of-life care across the UK.
