| Abstract | This research aims to evaluate the roles of a bulking agent as recycled compost and aerobic system in a composting technology called "serial self-turning reactors (STR)", using chicken manure as a substrate input. Group A was composted with sawdust in the partial aeration. While group B was processed with a forced aeration at 0.5 lit/min/kg organic matter, and the recycled compost was added beside sawdust. Each group was tested at different C/N ratios caused by different mixing ratios. The temperature was recorded every 5 minutes at 3 positions: middle, bottom and wall area of each reactor. The compost with group A did not meet the pathogen requirements in any cases and the temperature simply followed ambient temperature. Conversely, the temperature in all cases of group B rose up. Only 2 in 3 cases in group B met the thermophilic phase. And the other case, which did not reach into thermophilic phase, started with the largest amount of sawdust. Recycled compost provided the suitable porosity and maintained the beneficial microorganisms by supplying oxygen from the airflow. |
