As mentioned in the previous section under “All about Semakau Landfill”, Phase I has been completely filled to ground level. Filled cells are covered with soil and subsequently, grass and trees take root to form a green landscape, which becomes the main draw of eco-tourism and recreational activities. A separate area within the cell is used for solid waste disposal.
