Carbon dioxide and methane emissions during the composting and vermicomposting of sewage sludge under the effect of different proportions of straw pellets
Original language description
The objective of this study was to assess the carbon dioxide (CO2) and methane (CH4) emissions from sewage sludge composting and vermicomposting under the influence of different proportions of straw pellets. Four treatments were designed, by mixing the initial sewage sludge with varying ratio of pelletized wheat straw (0, 25%, 50%, and 75% (w/w)). The experiment was conducted for 60 days, and Eisenia andrei was used for vermicomposting. Vermicomposting significantly reduced CH4 emissions by 18-38%, while increasing CO2 emissions by 64-89%. The mixing agent (pelletized wheat straw) decreased CO2 emission by 60-70% and CH4 emission by 30-80% compared to control (0%). The carbon loss was 3,3-3,5% more under vermicomposting than composting. This study demonstrated that depending on the target gas to be reduced, composting and vermicomposting, as well as a mixing agent (pelletized wheat straw), could be an option for reducing greenhouse gas emissions (i.e. CH4, CO2).
