- Scotland legalizes hydrolysis, an environmentally friendly alternative to cremation and burial methods.
- The process uses alkaline solution to break down body tissue over three to four hours.
- Hydrolysis is already legal in 28 US states, Canada, Ireland, and several other countries.
Scotland has become the first UK nation to legalize hydrolysis, an environmentally conscious alternative to traditional cremation or burial. This legislative milestone represents the most significant shift in funeral practices since cremation was introduced in 1902. The process, also referred to as water cremation or aquamation, responds to growing public demand for sustainable funeral options and provides families with greater choice regarding end-of-life arrangements.
Hydrolysis mimics natural decomposition through accelerated chemical breakdown. The deceased is placed in a pressurized metal cylinder containing water mixed with 5% alkaline solution, typically potassium chloride, and heated to approximately 150 degrees Celsius. This three to four hour process dissolves soft tissue while preserving bone structure. The remaining bones are then dried and pulverized into fine white powder, which relatives can retain, scatter, or inter similar to conventional cremation ashes.
Scotland’s public health minister emphasized that hydrolysis offers a gentle, environmentally responsible choice. The procedure produces no direct toxic emissions and potentially eliminates the need for single-use coffins. Families selecting this method report viewing it as less environmentally damaging than conventional alternatives. The new option reflects broader societal awareness regarding environmental impact across all life decisions, including funeral arrangements.
Implementation will require time and coordination. Kindly Earth, which holds exclusive UK manufacturing rights for hydrolysis equipment, estimates nine months before the first Scottish facility becomes operational. Funeral directors must obtain planning permission and secure permits from local water authorities. The new method faces identical regulatory requirements as existing funeral practices, ensuring consistent safety and quality standards.
Hydrolysis already operates legally across 28 American states, Canada, Ireland, South Africa, Australia, and New Zealand. Archbishop Desmond Tutu selected water cremation for his funeral in 2022. Funeral industry professionals note that initial skepticism about cremation has transformed into broad acceptance, with cremations now representing nearly 80% of UK funerals. This historical pattern suggests similar eventual acceptance of hydrolysis as families become familiar with the option and its benefits.
