The biogas plant perfectly complements the industrial wastewater treatment plant and sewage sludge incineration plant. It allows us to recycle a wide variety of liquid and pumpable waste safely and efficiently.
The process begins with the co-digester, which sustainably breaks down the organic matter. The residual sludge is compressed and then incinerated for energy recovery in our sewage sludge incineration plant (SSIP). Used process water is treated at the wastewater treatment plant (WTP). The biogas generated by digestion is used to produce electricity, steam and biomethane. This innovative technology represents a sustainable treatment option for food refuse and biogenic waste flows, particularly from biochemical and pharmaceutical processes.
Since we can only accept digestible waste, our experts have to test the waste for digestibility before accepting the first shipment.
If the waste needs to be sanitized, we will take care of it at the biogas plant – there is no need for you to do anything.
