Cedrob Wastewater and Biogas Plant

Project’s context & challenges

Cedrob S.A., a leading poultry producer in Poland, aimed to become energy self-sufficient while reducing its environmental footprint. With multiple slaughterhouses, hatcheries, and feed production facilities, Cedrob needed a robust wastewater treatment and biogas recovery solution to handle complex and variable effluents. The goal: turn waste into value and meet stringent discharge standards.

Solution

Nijhuis Saur Industries (NSI), part of Saur Group, delivered a full-scale wastewater treatment and biogas plant for Cedrob. The system treats wastewater from slaughtering, poultry farms, and sanitation processes. It includes mechanical pre-treatment, dissolved air flotation, aerobic treatment, and advanced anaerobic digestion. The biogas is desulfurized and reused for heat production, while the digestate is dewatered and repurposed as fertilizer.
