The UK government and the Law Commission are considering the introduction of human composting and water cremation in England and Wales [1, 2].
These measures aim to provide more sustainable end-of-life options while addressing a growing shortage of burial space [1, 3].
Human composting, also known as natural organic reduction, converts human remains into soil. Water cremation, or alkaline hydrolysis, uses a chemical process to dissolve the body. Both methods are presented as greener alternatives to traditional burial and flame cremation [1, 2].
The evaluation of these practices began in 2024 [1]. While the UK is currently reviewing the legal framework for these processes, water cremation is already available in parts of Canada and Australia [1, 2].
The shift toward these technologies reflects a broader effort to reduce the environmental impact of the funeral industry. Traditional cremation releases significant carbon emissions, while traditional burials require land that is becoming increasingly scarce in urban areas [1, 3].
The Law Commission is tasked with examining how these methods would fit into existing laws regarding the disposal of human remains. This process includes determining the legal status of the resulting soil or remains, and ensuring that public health standards are maintained [1, 2].
“England and Wales are evaluating the introduction of human composting and water cremation.”
The move toward natural organic reduction and alkaline hydrolysis signals a transition in public health and environmental policy. By diversifying disposal methods, the UK can mitigate the land-use pressures on cemeteries and reduce the carbon footprint associated with traditional flame cremation, aligning funeral practices with broader climate goals.
