To this end, the background of research in this field was reviewed and globally available IT-based and non-IT-based methods to separate and collect this type of waste were identified. Next, activists and experts in the recycling industry were interviewed. Then, by reviewing the research literature and coding the interviews with experts, 20 strategies and 6 criteria were emerged for comparing the strategies. Finally, the TOPSIS method was used to prioritize these strategies. Based on the results of the TOPSIS method, the following options had the highest score in Iranian society respectively: adding the recycling section to existing platforms and supercharges, using separate applications for waste separation and collection, distributing separate bins to apartments, schools, and offices for waste separation.
