Biogas from the SSAD of dairy cattle manure, and the digestate of SSAD was fed to BSFL. In turn, BSFL can be fed to animals as a protein supplement. Adjustment of the pH and 30% inoculation ratio (IR 30 ) during SSAD produced the highest theoretical methane yield, 626.1 ± 28.7 L CH 4 /kg VS des with an ultimate methane yield of 96.81 ± 2.0 L CH 4 /kg VS load . For BSFL composting, the groups with a feeding rate of 75 and 100 mg/day/larvae had the highest body weight change, which was 969.6 ± 28.4% and 984.1 ± 177.6%, respectively. The combination process of SSAD and BSFL composting increases the incentive for dairy cattle manure treatment instead of conventional composting and produced more valuable products. © 2019 by the authors. |
