To assess the potentials of SWM to contribute to greenhouse gas (GHG) reduction and resource recovery, available technologies and strategies have to be analyzed. In this work, a SWM-GHG calculator was used to compare different potential strategies for waste management considering economic situation, environmental and social awareness in Jordan. Four scenarios representing the current and suggested technologies (increase recovery, biological treatment, and advance biological treatment) were studied. The results showed that a vast reduction of GHG emission of about 63,175 tons CO2-eq/year was observed in the fourth scenario where all the organic waste was recovered. Moreover, this scenario increased the net caloric values in reused waste from 8.4 to 9.6 MJ/kg. The results suggest that the SWM-GHG calculator can offer sufficiently accurate approximation of the GHG impacts of different suggested strategies in the country and can serve as an important contribution to decision makers.展开更多
