Water Cremation: water cremation becomes legal in Scotland

Scotland has become the first country in the UK where water cremation is now legal, offering families a third option alongside burial and traditional cremation. The move follows regulations introduced by the Scottish Government and approved by the Scottish Parliament, and the first procedures in Scotland are expected to take place this summer once all necessary consents are in place.

Scottish approval, previous ban and timeline for first procedures

The regulations enabling the practice were introduced by the Scottish Government and approved by the Scottish Parliament, making Scotland the first part of the UK to introduce the method after it had been effectively banned in the UK until now. the change will give an option for people interested in alternatives to burial or cremation for the first time in more than a century, and that it responds to significant public support for greater choice. The first procedures in Scotland are expected to take place this summer once all necessary consents are in place.

Water Cremation: the alkaline hydrolysis process explained

The process is officially called alkaline hydrolysis. Bodies are wrapped in a shroud of biodegradable material such as silk or wool before being placed in a pressurised chamber with hot water and chemicals, which speeds up decomposition. The procedure involves weighing the body, then heating it to 150C (300F) in a mixture of potassium hydroxide and water for up to 90 minutes; that dissolves the body tissue, leaving only the bones.

The bones are then rinsed at 120C, dried and pulverised into a coarse powder using a machine called a cremulator. The powdered remains can be returned to next of kin in an urn, in a way similar to ashes following cremation.

Environmental claims, timings and carbon figures

The method is commonly described as a "green cremation. " It has been estimated that a typical traditional cremation has a footprint equivalent to about 320kg of carbon dioxide, and alkaline hydrolysis is found to result in the emission of seven times less CO2. Other benefits put forward include no use of fossil fuels, a reduction in carbon dioxide and faster decomposition times; by comparison with burial — which can take up to 25 years for the body to decompose — water-based cremation can take just two to three hours.
