     the objective of this study was to investigate the feasibility of anaerobic co-digestion of kimchi factory waste silage (kfws) with swine manure (sm). chinese cabbage (cc) is the major waste generated by a kimchi factory and kfws was prepared by mixing cc and rice bran (rb) (70:30 on a dry matter basis). in experiment i, the biogas potential of cc and rb were measured and, in experiment ii, the test was conducted with different ratios of kfws and sm (kfws: sm = 0:100; 33:67; 67:33; 100:0 by% volatile solids (vs) basis). kfws produced a 27% higher biogas yield and a 59% higher methane yield compared to cc. the specific biogas yields increased by 19, 40 and 57% with kfws-33%, kfws-67% and kfws-100%, respectively compared to sm-100% (394 ml/g vs). similarly, vs removal increased by 37, 51 and 74% with kfws-33%, kfws-67% and kfws-100%, respectively compared to sm-100%. these results suggested that kimchi factory waste could be effectively treated by making silage, and the silage could be used as a potential co-substrate to enhance biogas production from sm digesters.
