| Abstract | The purpose of this research is to determine the best conditions for producing biogas from bedding material utilizing batch solid-state anaerobic digestion (SS-AD), which will then be employed in a new waste management technique in broiler farms. Total solid (TS) concentration (20% and 23%), fermentation method (continual mixing versus non-mixing), and CaCO3-pretreatment prior SS-AD were all investigated. The most suitable experimental setting for methane production and methane content were20% TS with CaCO3-pretreatment withcontinual mixing(test 1)at 77.1?2.7 NmL/gVSaddedand 73.2?2.2%, respectively. The optimal condition generated 2.5 times more methane than the condition without CaCO3-pretreatment and continuous mixing(test 3), and therefore 8.9 times more than the condition with a greater percentage of total solid (23% TS with CaCO3-pretreatment and continual mixingin test 5). In this study, continual mixingshowed inconclusive result on biogas outputwhich require further study. Alkaline pretreatment is suitable for broiler litter since it can weaken lignocellulose structure. In order to increase total solid concentration in SS-AD system, further studies on pretreatment methods are required. |
