Solid waste may be defined as any solid matter which is discarded as no longer useful in financial aspects. Solid waste includes any garbage (food waste and other degradable organic wastes), rubbish (combustible and non-combustible solid wastes), refuse (both garbage and rubbish), litters (paper bits, discarded wrappings, bottles, etc.), water supply treatment plant, sludge from a wastewater treatment plant, or air pollution control facility and other discarded materials (Tchobanoglous & Kreith, 2002). The sources of solid waste incorporate residential, institutional, commercial, 2industrial, mining, agricultural operations, and community activities (Table 1.1). Solid waste, if it is not handled properly, is the source of land, water, and air pollution.
