Approval of alkaline hydrolysis for animals
Alkaline hydrolysis (resomation/aquamation) is approved by the EU. There are various approaches to the approval of systems for the alkaline hydrolysis of animals. We have guided the entire approval process for Europe’s first facility for alkaline hydrolysis in an animal crematorium in accordance with EU regulations, and in the course of further approval procedures we have learned that there are currently some misunderstandings within the industry regarding what is permissible. To save you time, we have summarised the current situation and options in advance.
1
EU regulation for the alkaline hydrolysis of animals
The EU sets out approved methods that can then be used in member states. The requirements for a method approved under the EU regulation are as follows:
- at least 150°C
- at least 4 bar
to be maintained for 3 hours without interruption.
So-called ‘low-temperature systems’ are therefore not permitted. In point 2, you can see the differences between the two processes.

The difference between the process authorised under the EU Regulation and the ‘low-temperature process’
In general, a distinction is currently made between the ‘low-temperature process’ and the ‘standard’ process in accordance with the EU Regulation. Systems for the alkaline hydrolysis of animals that operate at temperatures below 150°C (these systems typically operate at around 94°C) are not permitted under the EU Regulation. In the Netherlands, however, such plants are still in operation. These are granted temporary approval for “research” purposes. It is therefore important to note that this approval strategy cannot work in many countries and that the long-term operation of these plants cannot be guaranteed. The Netherlands is an exception in this regard.
The advantage of “low-temperature systems” is that the initial investment and operating costs are lower. With our efficiency package and our patented process, we can largely mitigate this effect.
