Anaerobic treatment of chicken manure co-digested with sawdust
The high total nitrogen content of chicken manure (CM) makes it suitable to undergo anaerobic digestion (AD) for the production of biogas. In this study, AD of CM was done using sawdust (SD) as co-substrate to investigate the quality of biogas produced. CM and SD were mixed to reach different carbon...
