Resum:	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.
