100% Biogas Energy Recovery. Using sludge-sourced biogas to produce steam.
The challenge
When new regulations required Bonduelle to build a wastewater treatment plant for its food processing factory in Békéscsaba, Hungary, the company turned to Veolia, whose specialists suggested a solution using sludge-sourced biogas to produce steam.
As Veolia exploits the biogas successfully in Nagykőrős, Bonduelle decided to use biogas also in Békéscsaba:
- Recover available biogas produced by a wastewater treatment plant with UASB technology
- Improve energy efficiency
- Optimize energy costs which challenges solve the inventions using biogas
Veolia’s solution
- Renovation of the energy plant: 2 boilers in Békéscsaba
- Adaptation of one of existing boilers for the combustion of biogas
- Biogas parameters:
- Pressure: 23-27 Mbar
- Temperature: 35° C
- Production of steam at 180° C, 10 bar
- Flexibility to adapt to seasonal nature of production
