The UK’s biggest funeral care provider has announced that it will start offering water cremation, also known as resomation, services later this year. But what exactly is it and what is its impact on the environment?


The UK will offer water cremation for the first time this year, following rising demand for more environmentally friendly end of life options.

When you die there’s currently only two options in most of Europe - burial or a traditional fire cremation.

But new options are being explored.

What is water cremation or resomation?

Water cremation, also known as aquamation, resomation and alkaline hydrolysis, uses water to bring the body back to the skeletal remains.

The body is placed in a steel vessel filled with water and an alkaline solution.

It is then heated up which takes the flesh back to its chemical components - amino acids, peptides, sugars and salts.

After about three to four hours, only the bones remain.They are then ground down to a white powder, placed in an urn and given to the family.

The UK’s biggest funeral provider, Co-op Funeralcare, has announced that it will introduce the practice later this year. Water cremation was already legal in the UK subject to compliance with health, safety and environmental regulation, but this is the first time it will be widely on offer in the country.

It’s the method that South African anti-apartheid hero Desmond TuTu chose following his death in 2021.

He wanted an eco-friendly funeral and according to UK-based firm Resomation, it uses five times less energy than a fire cremation.

What is the environmental impact of the funeral industry?

“For decades there have been just two main choices when it comes to [peoples’] end-of-life arrangements: burial and cremation,” says Julian Atkinson, director of resomation company Kindly Earth.

“[We] will be providing people with another option for how they leave this world because this natural process uses water, not fire, making it gentler on the body and kinder on the environment.”

And there appears to be an appetite for such a service.

Research by YouGov, commissioned by Co-op Funeralcare, found that 89 per cent of UK adults hadn’t heard of the term resomation. But once explained, just under a third (29 per cent) said they would choose it for their own funeral if it was available.

“The rise in ecological and sustainability concerns over the past decade combined with a desire to be part of nature or laid to rest in a natural setting, means more people are considering the environmental impact of their body once they die,” says Professor Douglas Davies from the Department of Theology and Religion at Durham University.

Around 245kg of carbon emissions are generated by one traditional cremation, the equivalent of charging your smartphone over 29,000 times.

Traditional burials also have negative environmental consequences. The chemicals used in the embalming process can leak out and pollute the surrounding soil and waterways.

What other countries offer water cremation?

The UK is not the only European country to make waves in the resomation scene.


Ireland is set to open its first water cremation facility this year. The service is also available in the US, Canada and South Africa.

Belgium and the Netherlands are among the other European countries looking to introduce resomation, but there are regulatory hurdles that must be overcome first.
