Abstract

Present study of the biofuel potential of rice straw (RS) waste biomass materials. The average activation energy of rice straw was determined from KAS, FWO and Starink are 84.11, 89.62 and 84.52 kJ/mol, respectively. The characterized rice straw biomass has been tested for biogas potential under co-digestion mode of rice straw and cow dung in ratio 1/2. The maximum 339 ml/g Vs of biogas has been recorded in 35 days with CH4 concentration of 58.3%. The rest being CO2 as well as H2S has been found in trace amounts with observed 85% total solids and 74% volatile solids, present in rice straw.
