Boil in the bag’ environmentally friendly funerals

With a lower carbon footprint than gas-fired cremation, the process is described as ‘gentler on the body and kinder on the environment’

For anyone uneasy at the thought of their body being consumed by flames or interred in an insect-teeming grave, a new funeral choice is about to become available: water cremation

The process of dissolving a body in a bag in 160C water treated with an alkali will become available in the UK later this year and is the first new legal method of disposing of cadavers since the Cremation Act of 1902. It has been described as a “boil in the bag” funeral.

With a carbon footprint that is claimed to be about half of that of gas-fired cremation, the process leaves only bones, which are then powdered and returned to the family in the same way as cremated ash.

For the water cremation it would be wrapped in a woollen shroud and placed in a “bio pouch” made from cornstarch. This would then be placed in a sealed chamber with 95% water and the remainder potassium hydroxide and heated to about 160C. After four hours everything but the skeleton would be dissolved.

To ensure this process runs smoothly, reliable filtration and compatible materials are essential—especially when dealing with large-scale or repeated aquamation cycles.

Our company proudly supplies:

Filter bags specifically designed for alkaline hydrolysis systems, capable of capturing bone fragments, hair, and other solid residues without clogging or chemical degradation.
Corrosion-resistant bags and liners to contain remains during the cycle.
Alkaline-compatible materials and system accessories used by aquamation facilities, veterinary clinics, and funeral homes.

All of our filtration products are made with durable, high-temperature-resistant materials such as PE or PP, with customized micron ratings (6μm, 15μm, 30μm, etc.) to meet specific system needs. Whether you’re operating a low-pressure human aquamation unit or a high-efficiency pet cremation system, we can help you find the right solution.
