Abstract |
|
|
| Municipal Solid Waste (MSW) is the waste generated by domestic, commercial, industrial, healthcare centres, agricultural, and mineral extraction activities, which accumulate in streets, drainages, and public places. These wastes produce toxic substances such as dioxins, polyaromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs), furans, etc, that are emitted into the environmental media such as air, soil, and water, and are considered harmful to the human system and the environment. These substances affect human organs such as the liver, lungs, kidneys, etc. Environmental issues such as ozone layer depletion and climate change are serious issues of concerns. This study considers the prioritization of the major components of solid waste based on their effects in Ganye Metropolis in Adamawa State, Nigeria. Analytical Hierarchy Process (AHP) was used to analyzed and prioritized the components of solid waste, which include: organic waste, plastics and polythene, paper and cardboard, metals, electronic waste, medical waste, and glass and ceramics. Five criteria were identified and considered to assess the major components of the solid waste. The criteria are: environmental, health, agricultural, economic, and social effects. Data were collected from environmental, health, agricultural, and economic experts, and community leaders in Ganye metropolis. Saaty’s nine-point scale structured questionnaire was used. The Geometric Mean was used to aggregate the responses from the multiple respondents to drive the weights of the criteria. Based on the analysis, the result shows that plastics and polythene (PL) ranked first (1st), followed by organic waste (OR) which ranked second (2nd), paper and cardboard (PC) ranked third(3rd), glass and ceramic (GC) ranked fourth (4th), metals (MT) ranked fifth (5th), medical waste (MD) ranked sixth (6th) and electronic waste (EL) ranked last. Plastics and Polythene, which have the highest priority weight, should be given attention during solid waste management in Ganye Metropolis. |
