Open-access Effect of ph and temperature on biogas production from rice hulls

Rica hulls were studied in order to examine their potential for biogas production. The material was previously treated with 5, 10 and 15% NaOH W/W and incubated at temperatures of 40 and 60º C. Results showed that rice hulls were not good for methane production, but the total production of gases increased with temperatura and alcali concentration up to 10%.
