Thisapproach requires <strong>the</strong> same th<strong>in</strong>k<strong>in</strong>g and structure as <strong>the</strong> <strong>in</strong>c<strong>in</strong>erat<strong>in</strong>g & 1andfill:<strong>municipal</strong> <strong>solid</strong> <strong>waste</strong> cou1d be separated <strong>in</strong>ta <strong>in</strong>organic <strong>waste</strong> and organic <strong>waste</strong>. The<strong>in</strong>organic component is treated <strong>in</strong> sanitary 1andfill, <strong>the</strong> organic <strong>waste</strong> is used toproduce biogas and compost. Based on this approach <strong>the</strong> causa1 100p diagram hasbeen drawn <strong>in</strong> Figure 9 to show <strong>the</strong> compost<strong>in</strong>g & 1andfill processurban population &economic growth<strong>in</strong>vestment<strong>of</strong> sanitarylandfiIIcropsproductionloss+arable landfordump<strong>in</strong>gC!!Jtransportationcost &pollutionC!!)<strong>municipal</strong> <strong>solid</strong><strong>waste</strong> generated+1- I ooooom;obenefitstransportation I I <strong>in</strong>vestment<strong>of</strong> I I from sell<strong>in</strong>sortmgeconomicfrom sell<strong>in</strong>g <strong>of</strong> biogasbenefits II<strong>in</strong>vestmentbIOgas compost plantsanitarylandfiIIFigure 9.
