This work reviewed the past and current status of municipal solid waste (MSW) management in Nigeria towards offering a direction for the future. The past status shows that poor policy regimes, inadequate financing mechanisms, absence of waste data, and abysmal institutional arrangement negatively impacted the MSW management outcomes in the country. At present, few improvements recorded like an increase in the number of landfills, and public-private partnerships have been largely undermined by the continuous upsurge in the urban population and lack of corresponding growth in critical capacities in terms of economic resources, technological advancement, and state-of-the-art urban infrastructures. The current waste generated in cities in Nigeria is calculated as 66,828 tonnes per day (TPD) at the total urban population of 106 million, while the projected value for 2040 will be 125,473 TPD at the urban population of 199 million. The current work further discusses prospects and implications for circular economy adoption in solid waste valorization in Nigeria.
本文回顾了尼日利亚过去和现在的城市固体废物（MSW）管理状况，为未来提供了一个方向。过去的情况表明，政策制度不完善、资金机制不足、缺乏废物数据以及糟糕的机构安排，对该国的 MSW 管理成果产生了负面影响。目前，记录到的一些改进，如增加了垃圾填埋场的数量和公私合作伙伴关系，在很大程度上被城市人口的持续增长和经济资源、技术进步以及最先进的城市基础设施方面的关键能力的相应增长所削弱。目前，尼日利亚城市每天产生的垃圾量为 66828 吨，总城市人口为 1.06 亿，而到 2040 年，城市人口为 1.99 亿时，预计将达到 125473 吨。目前的工作还进一步讨论了在尼日利亚固体废物增值利用中采用循环经济的前景和影响。
