The wet season municipal solid waste (MSW) was characterized on Lasoju/Eyenkorin dumpsite for May to August 2020. The aggregate of waste generated was estimated to be 135,882 tons, while the aggregate characterized was estimated to be 80,700 tons. There are thirty-two samples of 240 L (bin of MSW) per sample considered in this investigation. There are twenty-one waste components categorized altogether, with packaging box having the highest proportion of 10.04%, followed by food residue of 9.64%, nylon 9.51%, and leather with the least fraction (0.75%) of the weight basis. Experimental investigations were performed on fourteen combustible fractions of the waste to determine the moisture content, elemental contents, and high heating value. The laboratory analysis reveals that the average carbon content available is 55%, 7% hydrogen, 1.35% nitrogen, 0.44% sulphur, and 30% oxygen; the low heating value of the waste was determined to be 23 MJ/kg. About 672 tons of MSW were investigated for energy production to give an energy and power potentials of 4.2 GWh and 53 MW discretely. The estimated electrical power potential for the wet season MSW is capable of meeting about 59% of the power demand for the Ilorin metropolis.
对2020年5月至8月拉索朱/艾延科林垃圾填埋场的雨季城市固体废物（MSW）进行了特性分析。产生的垃圾总量估计为135,882吨，而进行特性分析的总量估计为80,700吨。本调查共考虑了32个样本，每个样本为240升（城市固体废物箱）。总共分类了21种垃圾成分，其中包装盒占比最高，为10.04%，其次是食物残渣，占9.64%，尼龙占9.51%，皮革占比最小（0.75%，按重量计）。对该垃圾的14种可燃成分进行了实验研究，以确定其水分含量、元素含量和高热值。实验室分析表明，可用的平均碳含量为55%，氢含量为7%，氮含量为1.35%，硫含量为0.44%，氧含量为30%；该垃圾的低热值确定为23兆焦/千克。对约672吨城市固体废物进行了能源生产调查，分别得出能源潜力为4.2吉瓦时，电力潜力为53兆瓦。雨季城市固体废物的估计电力潜力能够满足伊洛林市约59%的电力需求。
