Municipal waste transfer stations (WTS), operate as middle elements in waste collection and transfer to the final disposal site. Besides their benefits in waste transportation cost reduction, WTS can cause negative environmental impacts such as noise, air, and water pollution. Environmental impact assessment is an effective solution to reduce the environmental impacts of WTS. This research was conducted at evaluating the environmental impacts of various options defined for WTS in Tehran using the Rapid Impact AssessmentMatrix (RIAM) analysis method.
This descriptive-analytical study was performed to assess the environmental impacts of WTS based on field observation and data collection. Comparing was included four options including: continue the current condition of the WTS, three other alternatives considered to be three other alternatives (WTS in open space with the construction of green space) and transfer in enclosed space and with construction of green space and without it. Finally, using the sustainability model, the stability of the options was also measured.
Based on the obtained results, the fourth option (indoor loading/unloading along with establishment of green spaces in WTS) as the first priority for the Construction of transfer stations among the other options has the highest score (0.079) in terms of sustainability as well as the adverse environmental impacts. However, the current environmental status of Tehran WTS (first option) has the lowest score (-0.213) in terms of sustainability and the most destructive environmental impacts and found to be the last priority in establishment of transfer stations.
Combined use of the RIAM and sustainability model can be a promising and reliable way to evaluate and improve the performance of (WTS).
