Environmental impact assessment (EIA) for waste disposal options to examine their impacts is of great importance. Rapid impact
assessment matrix (RIAM) was used in this research to evaluate impacts of the four different MSW disposal scenarios in Abyaneh
village which is one of the oldest villages in Iran, attracting numerous domestic and international tourists year-round. These
scenarios, respectively, were open dumping (S1), sanitary landfilling (S2), composting, followed by sanitary landfilling of the
residual wastes (S3) and recycling of inorganic wastes, composting of organic wastes, followed by sanitary landfilling of the residual
wastes (S4). The existing MSW practice in Abyaneh (S1) was estimated to cause maximum negative effects on physical/chemical
(PC), biological/ecological (BE), sociological/cultural (SC) and economical/operational (EO)components of the environment.
Positive and negative values for scenarios 2-4, respectively, are (-475/+20), (-640/+129) and (-251/+41). Thus, according to the
results, open dumping replacement priorities are, S4, S2 and S3 scenarios, respectively. Evaluating the potential sustainability of
different project scenarios showed that scenario 4 and scenario 1, with the S-value equal to –0.552 and - 0.786, repectively, had the most and least sustainability.
