Management of sewage sludge is one of the biggest challenges for water utilities; it dictates the efficiency of material recovery in the city and fate of pollutants and pathogens in wastewater. An incubation study is conducted to estimate the impact of stabilization technique to greenhouse gas (GHG) emission after land application. Anaerobic digestion and composting are considered. The results show that stabilization measures can bring added benefit of GHG emissions reduction, as well as conventional target of odor, pathogen risk and volume reduction. Conversely, amount of bioavailable and leachable phosphorus has affected little by the stabilization measures.
