dc.abstract.enThis study evaluated the effectiveness of microbial compositions (Pseudomonas fluorescens, Pseudomonas putida, Bacillus licheniformis, Lactobacillus fermentum, Lactobacillus plantarum, and Pediococcus sp.) in reducing greenhouse gas (GHG) and odour emissions from stored poultry manure. The research consisted of two phases: (EI) a controlled 11-week column experiment with chicken manure under static chamber conditions, and (EII) a 42-week in situ experiment on chicken and turkey manure piles. Gas emissions (CO2, CH4, NH3, H2S, O2) were monitored using NDIR (nondispersive infrared) and electrochemical sensors, while GC-MS analysis assessed volatile organic compounds. Results indicated that microbial treatments accelerated organic matter decomposition, increasing CO2and H2S emissions compared to controls. However, they significantly reduced NH3 (by up to 83%) and hydrogen cyanide (HCN) concentrations, demonstrating potential for odour mitigation. In in situ trials, turkey manure exhibited higher initial odour intensity (4.5 compared to 4.1 on a 5-point scale at 1 m distance), but both manure types stabilised to negligible levels (~1.2) after 9 weeks. Temperature and humidity strongly influenced emissions, with higher NH3 release observed at warmer temperatures (17–19°C) and moderate humidity (64–69%). The study highlights the trade- off between microbial treatments’ benefits (NH3 reduction) and drawbacks (elevated CO2/H2S). Further optimisation of bacterial strains and integration with aerobic composting is recommended to balance emission control with nutrient retention. These findings contribute to sustainable manure management strategies aligned with circular economy principles.

dc.description.abstract<jats:p>This study evaluated the effectiveness of microbial compositions (Pseudomonas fluorescens, Pseudomonas putida, Bacillus licheniformis, Lactobacillus fermentum, Lactobacillus plantarum, and Pediococcus sp.) in reducing greenhouse gas (GHG) and odour emissions from stored poultry manure. Two experimental phases were conducted: an 11-week controlled column experiment under static chamber conditions and a 42-week in situ experiment on chicken and turkey manure piles. Gas emissions (CO₂, CH₄, NH₃, H₂S, O₂) were monitored using nondispersive infrared and electrochemical sensors, while volatile organic compounds were analysed by GC-MS. Microbial treatments accelerated organic matter decomposition, increasing CO₂ and H₂S emissions, but significantly reduced NH₃ (up to 83%) and hydrogen cyanide concentrations, demonstrating effective odour mitigation. In situ trials showed higher initial odour intensity for turkey manure, but both manure types stabilised to negligible levels after nine weeks. Emissions were strongly influenced by temperature and humidity. The study highlights a trade-off between reduced NH₃ emissions and increased CO₂/H₂S release, indicating the need for optimisation of microbial treatments combined with aerobic composting to support sustainable manure management and circular economy principles.</jats:p>
