The NH 3 emission was significantly increased by 4.3–7.9 times in CS and CRM, compared to OC and CC. It indicated the importance of selection for co-composting material. ![]() The results showed that cumulative flux of carbon dioxide (CO 2), methane (CH 4), nitrous oxide (N 2O) and ammonia (NH 3) widely ranged like 38,211–50,830, 172–417, 98–142 and 118–927 g kg dm −1 day −1 respectively. In this study, pilot-scale experiments were conducted to characterize the co-composting process of chicken manure with cow manure (CC), swine manure (CS), plant residues plus mushroom media (CRM), on emissions of greenhouse gas, and ammonia, compost quality, maturity and their correlations. ![]() Co-composting of organic wastes is globally recognized to be effective method to dispose two or more wastes at once and minimize drawbacks of composting such as gases emissions and nutrient reduction.
