This e-module presents the meat processing industry demonstration under the AccelWater project, showcasing innovative water treatment technologies applied at the MAFRICA slaughterhouse in Spain. Led by the BETA Technological Center, the demonstration integrates membrane bioreactors, electrodialysis, UV disinfection and freeze concentration to enable water reuse and nutrient recovery. These methods successfully recovered 92% of treated water and significantly reduced the facility’s water footprint. The module highlights how advanced treatment solutions and evolving regulations support a circular water economy and enhance sustainability in the food processing sector.
