Abstract

An attempt was made to tap the renewable energy (biogas) potential of rice straw under varying Organic Loading Rate (L_R) using a Plug Flow Reactor (PFR) running at mesophilic temperature (37°C). A 140-litre capacity PFR was filled with 105 litres pre-cultivated sludge as inoculum, leaving a headspace of 25% for gas production. The loading of the rice straw into the reactor was commenced at a low L_R of 0.5 goTS/l.d and was increased weekly by 0.5 goTS/l.d until a L_R of 4.5 goTS/I.d was attained. The biogas produced was collected in a gas bag (LINDE), measured with a multi-chamber rotor gas meter (RITTER) and analyzed using an Infrared Gas Detector, PRONOVA. It was established that the biogas yields increased with increase in L_R. The highest biogas yields of 0.20 I/goS was recorded at the L_R of 0.5 goTS/I.d after which some relatively constant yields were observed. In all, rice straw has been established to have high energy value with prolonged hydraulic retention time at low L_R and this could help in meeting the energy demand of the masses.
