Abstract

A massive measure of waste gets produced following the harvest of sugarcane which is one of the foremost crops cultivated in the subtropical regions all over the world. Degradation of these lignocelluloses wastes takes a long time naturally and hence disposed of through open burning that in turn consequences atmospheric pollution. These tribulations could be detached on practicing the rapid degradation method called anaerobic digestion method. The present study assesses the effect of mixing speed on biogas production through anaerobic digestion of sugarcane trash. The study was intended to get the effect of mixing speed on the degradation of lignocelluloses and in biogas production from sugarcane trash substrate inoculated with dairy manure. In this study, the anaerobic digestion process was kept under mesophilic conditions of 320C for 30 days in a batch feed anaerobic digester at differential mixing speeds of 0 rpm, 50 rpm, 100 rpm and 150 rpm. Results showed that better degradation of lignocelluloses and high production of biogas (109.55 mL gVS-1) was observed in the reactor R3 (100 rpm) and the value was at the least in the reactor R1 where mixing was not provided. Hence, it was observed that the mixing speed greatly affect biogas properties of sugarcane trash that undergo batch fed anaerobic digestion process.
