Sludge recycling technology demonstrably saves CO2
With the CTC process, combustion takes place in a fluidized bed reactor and at an exactly controlled combustion temperature. During the process, the water contained in the sludge is evaporated, organic fractions are incinerated and the minerals contained are converted into a mixture of calcium carbonate, free lime and metakaolin. Depending on the composition, the mineral can be used as a hydraulic binder or pozzolan in the construction material sector without further post-treatment.
