     this work aimed to demonstrate in a pig farm and in real conditions, the possibilities to co-digest wasted sardine oil (wso) and pig slurry (ps) at farm scale. a biogas mobile pilot plant, was set up in the farm and operated in real conditions during 4 months. dynamic mesophilic (35–37 °c) continuous pilot trials were performed during four different periods of time. in each period a different organic loading rate (olr) based on the chemical oxygen demand (cod) was operated sequentially, with pig slurry (ps) (olr = 1.6 kg cod/m3 d−1) and with mixtures of wso:ps with a volumetric composition (% v/v) of 2:98 (olr = 3.0 kg cod/m3 d−1), 3:97 (olr = 3.7 kg cod/m3 d−1) and 5:95 (olr = 5.2 kg cod/m3 d−1). biomass adapted very fast in metabolise the wso and biogas productivity was raised substantially for different compositions of wso:ps. process stability indicators ph and total volatile fatty acids/bicarbonate alkalinity (t-vfa/ba) ratio, suggests that the co-digestion process was robust. it was concluded that wso could be easily co-digested in farm scale biogas plants.
