Thickening digestate with residual heat from gas engine

Thickening digestate with residual heat from gas engine

During the AquaNederland trade fair, we received several questions about the thickening digestate, using residual heat from, for example, a gas engine.

With CRESCENDO, Cirtec has a technology with which low-grade heat can be usefully applied for the thickening/evaporation of concentrated liquid streams, such as digestate. In order to show the working principle and simplicity of the CRESCENDO technology to interested parties, CirTec and Oosterhof Holman are organising a demonstration test, in which digestate from a co-digester is extensively thickened.

The demonstration test takes place in Grijpskerk and on May 7, 15 and 16, visitors are welcome to visit the installation. If you are interested, please send an email to so that we are aware of your visit.
