•Emission factors for MSW and organic fraction of MSW composting have been determined.•Polyethylene tube has been compared to wood chips as bulking agent.•Use of polyethylene tube as bulking agent reduces NH3, CH4 and VOC emissions.•Alpha and beta pinene emissions are related with wood bulking agents.•Terpenes are predominant VOC in all the processes, being limonene the most abundant.
In this study, the emissions of volatile organic compounds (VOC), CH4, N2O and NH3 during composting non-source selected MSW, source selected organic fraction of municipal solid wastes (OFMSW) with wood chips as bulking agent (OF_wood) and source selected OFMSW with polyethylene (PE) tube as bulking agent (OF_tube) and the effect of bulking agent on these emissions have been systematically studied. Emission factors are provided (in kg compound Mg−1 dry matter): OF_tube (CH4: 0.0185 ± 0.004; N2O: 0.0211 ± 0.005; NH3: 0.612 ± 0.269; VOC: 0.688 ± 0.082) and MSW (CH4: 0.0549 ± 0.0171; N2O: 0.032 ± 0.015; NH3: 1.00 ± 0.20; VOC: 1.05 ± 0.18) present lower values than OF_wood (CH4: 1.27 ± 0.09; N2O: 0.021 ± 0.006; NH3: 4.34 ± 2.79; VOC: 0.989 ± 0.249). A detailed composition of VOC is also presented. Terpenes were the main emitted VOC family in all the wastes studied. Higher emissions of alpha and beta pinene were found during OF_wood composting processes.
