Chlorophenol compounds are environmental pollutants that are both anthropogenic and xenobiotics. Some of these chemicals are carcinogenic and toxic to a number biochemical processes. The present research aims at 2-CP degradation in a UASB reactor with starch water as co-substrate. Synthetic 2-CP and starch water were given as feed to UASB reactor at an HRT of 24 h. The performance of the reactor was remarkably stable and efficient during 2-CP additions at a range of 5-800 mgL-1. The reduction of 2-CP and COD was found to be 100-67.9 and 98.1-59.3% respectively. The optimum 2-CP and COD removal efficiencies were 97.5 and 90.4%. The VFA concentrations of the reactor were lesser than 250 mgL-1. The biogas production at 600 mgL-1 of 2-CP was 20 Ld-1.
