Specifications table Data, experimental design, materials and methods Scenario Sc-0 (Currently in-use scenario): In this scenario, MSWs are subjected to an AD process. As Fig. 1 shows, MSWs are transported to the treatment center, where the organic fraction are separated by a sorting process and are introduced to the AD plant. The inorganic fraction (rejected waste) is subjected to a landfilling process and recyclable materials such as aluminum, polyethylene terephthalate (PET), glass, iron sheet, cardboard, plastic bags and other plastics are separated for a recovery process. Finally, electricity and heat are generated through the AD process. There are 4 main steps involved in this scenario including: transportation, sorting, landfilling and AD. The inventory data for nucleoside analogs consumption and environmental emissions were collected for each stage (Supplementary file 1; Scenario Sc-0, Inventory Data.xlsx). Scenario Sc-1 (Fading scenario): In this scenario, MSWs are subjected to a landfilling process in combination with a composting process (without biogas delivery from the landfill site). There are 4 main steps involved in this scenario including: transportation, sorting, landfilling and composting. The inventory data for energy consumption and environmental emissions were collected for each stage (Supplementary file 2; Scenario Sc-1, Inventory Data.xlsx) Fig 2. Scenario Sc-2 (Future scenario): This scenario represents incineration technique in which all the MSWs are incinerated after removing the recyclable materials (Fig. 3). Transportation, sorting and incineration are the major steps involved in this scenario. The inventory data for energy consumption and environmental emissions were collected for each stage (Supplementary file 3; Scenario Sc-2, Inventory Data.xlsx). Scenario Sc-3 (Future scenario): This scenario represents incineration in combination with composting process (Fig. 4). The only difference between this scenario and the scenario Sc-2 is that the organic fraction of MSW is subjected to an aerobic maturation in the composting process. There are 4 main steps involved in this scenario including: transportation, sorting, composting and incineration. The inventory data for energy consumption and environmental emissions were collected for each stage (Supplementary file 4; Scenario Sc-3, Inventory Data.xlsx). Scenario Sc-4 (Future scenario): This scenario is a combination of AD technique and incineration process (Fig. 5). MSWs are transported to the center and subjected to a sorting process. Organic matters are subjected to the AD process for biogas production and consequent production of electricity and heat. Rejected wastes are subjected to the incineration process for electricity production. Also, recyclable materials would be separated for a recovery process. Transportation, sorting, AD and incineration are the main steps involved in this scenario. The inventory data for energy consumption and environmental emissions were collected for each stage (Supplementary file 5; Scenario Sc-4, Inventory Data.xlsx)).
