Abstract

The biomethanisation of pig wastes produces a significant amount of biogas and reduces the organic load of the effluent. This effluent contains an important amount of nutrients that may be recuperated by coagulation-floculation, with cationic polymers. The optimization of this process was studied and the characteristics of the solid wastes produced determined. This product is a typical protein concentrate whose value is discussed, as well as possible reutilizations for feeding purposes.
