Item Characterization and Management of Solid Waste Generated in Nasarawa LGA in Nasarawa State, Nigeria(Middle-East Journal of Scientific Research, 2016-01-18) Nasir, .A.; Kasimu, .U.; Bori Ige; Mohammed, .A.Solid wastes constitute a significant amount to environmental hazard in the society. The need to characterize solid wastes as an initial step to proffer solution to the problem of solid waste management cannot be over emphasized. In Nasarawa local government area (LGA) in Nasarawa state, the solid waste materials are characterized into six (6) different materials type which includes paper/cardboard, plastic food pack/plastic bottles, metal cans, food waste, polythene bags/polystyrene food pack and other combustible miscellaneous waste material. The waste characterization shows that Polythene bags/polystyrene food packs constitute the highest waste of 141.09 kg/day collected during the study period. This is followed by food waste with 130.37 kg/day. Plastic food pack/plastic bottles, metal cans, paper/cardboard and others has 64.64 kg/day, 59.39 kg/day, 53.51 kg/day and 29.15 kg/day respectively. The non-biodegradable wastes such as polythene bags/polystyrene food pack, plastic food pack/plastic bottles and metal cans constitute about 56 % (257 Kg/day) of the total waste collected during the study period. It is recommended that Nasarawa state waste management scheme should include the adoption of 3R’s methods scheme for reducing the biodegradable waste components and also employed for reducing the non-biodegradable waste components.Item Modeling the Energy Content of Municipal Solid Waste (A Case Study of Minna Metropolis)(African Journal of Renewable and Alternative Energy (AJRAE), 2019-07-11) Ibrahim, .M.; Babawuya, .I.; Enagi, .I.; Mohammed, .A.; Suleiman, .I.; Bori Ige; Garba, .M. U.Waste management has assumed importance due to environmental hazards and rapid depletion of the resources of almost all the minerals. Considering the bulk quantity which form the waste in municipal areas, its utilization is posing a challenge to the environment and our natural resources. A physical characterization was performed in 120kg of MSW sampled for one week. Also an ultimate analysis was carried out on 2kg sample of waste mixed thoroughly. The results of physical characterization show there are 30.58% of paper, 29.53% of plastic, 17.17% of food waste, 32.83% of polythene, 16.42% of metals and 18.58% of glass wastes respectively. Also the ultimate analysis shows that there are 36.53% of carbon. 10.09% of Nitrogen, 3.39% of Hydrogen, and 1.10% of Sulphur, 37.37% of ash content and 11.52% of oxygen content respectively. About 23,450kg of waste was open dumped by NISEPA trucks during the study period. A HHV of 5840659.35KJ/120kg was obtained, and it was also found that approximately 488MW of electricity could be generated from waste materials dumped at the landfill annually.
