In a landmark decision, Scotland has officially become the first region in the United Kingdom to legalise hydrolysis, a sustainable alternative to traditional cremation and burial practices. This innovative method, also known as water cremation or aquamation, responds to growing public demand for environmentally friendly funeral options. The Scottish Parliament’s approval of this legislation on 2 March 2026 marks a significant evolution in funeral law, the first substantial change since the introduction of cremation over a century ago.
The Hydrolysis Process Explained
Hydrolysis mimics the natural decomposition process, significantly accelerating it. During this method, a deceased body is placed in a pressurised metal cylinder filled with a mixture of water and a 5% alkaline solution, such as potassium chloride. The cylinder is then heated to approximately 150°C (300°F) for a period of three to four hours. This procedure effectively dissolves body tissues, leaving behind only bones, which are subsequently dried and ground into a fine, white ash. Families will receive this ash in an urn, allowing them the same options for memorialisation as with conventional cremation ashes—scattering, keeping, or burying.
Government Perspectives on Sustainable Funerals
Scottish Government’s Public Health Minister, Jenni Minto, expressed her support for this new option, highlighting the personal nature of decisions surrounding remains. “Hydrolysis offers a new, environmentally friendly alternative to burial or cremation, responding to significant public support for greater choice,” Minto stated. She emphasised that this process will adhere to the same regulatory standards as existing funeral methods, ensuring safety and respect for the deceased.
Kindly Earth, the exclusive manufacturer of hydrolysis equipment in the UK, anticipates a timeline of up to nine months before the first Scottish facility becomes operational. This includes securing planning permissions and permits from local water authorities. Helen Chandler, the general manager at Kindly Earth, remarked on the importance of choice in funeral arrangements, acknowledging the diversity of values and priorities among different families.
A Global Perspective on Hydrolysis
Hydrolysis is not a novel concept; it has already been legalised in 28 US states, as well as in countries like Canada, Ireland, South Africa, Australia, and New Zealand. Notably, the late Archbishop Desmond Tutu opted for water cremation for his funeral in 2022, highlighting its acceptance among various cultures and beliefs. Families choosing hydrolysis often cite the process as a gentler and less environmentally damaging alternative. Unlike traditional cremation, hydrolysis produces no direct toxic emissions into the atmosphere and has the potential to eliminate the need for single-use coffins.
Meanwhile, the Law Commission in England and Wales is currently examining the need for a regulatory framework for alternative funerary methods, including hydrolysis and human composting. This reflects a broader societal shift towards sustainability in end-of-life practices.
Changing Attitudes Towards Funeral Choices
Andrew Purves, the chief operations officer at William Purves Funeral Directors, noted a noticeable increase in families expressing interest in sustainable funeral options. He remarked, “We’re all aware of the environmental impact we have in our lives, and spend a lot of time choosing what we recycle… so it’s only right that people should be able to consider that for their funeral too.”
Historically, the introduction of cremation faced scepticism, similar to what hydrolysis may encounter as it gains recognition. However, Purves anticipates that just as cremation is now embraced by nearly 80% of UK funerals, hydrolysis will eventually find its acceptance within society.
Why it Matters
The legalisation of hydrolysis in Scotland is more than a mere procedural change; it signifies a critical shift towards acknowledging and addressing the environmental impacts of funeral practices. As public awareness grows regarding sustainability, this innovative method not only provides families with an additional option but also encourages a broader dialogue about the ecological footprint of death. By making this choice available, Scotland sets a precedent that could influence funeral practices across the UK and beyond, paving the way for future developments in eco-friendly arrangements.
