Abstract

Pig slurry from modern high-technological farms contain copper and zinc, which is under suspicion of being co-factors in the development of antibiotic resistance. In addition, these two elements contaminate the surrounding environment when spread in large quantities. Therefore, biogas plants and biomembranes should be used to remove hazardous substances such as copper, zink, antibiotics and antibiotic resistant bacteria before pig slurry is used as a fertilizer in crop production. That would allow recycling of phosphorous in a way that only to a limited extent affect the health of the environment.
