Temporal assessment of municipal solid waste management in Nigeria: prospects for circular economy adoption.

Abstract

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 66,828tonnes per day (TPD) at the total urban population of 106million, while the projected value for 2040 will be 125,473TPD at the urban population of 199million. The current work further discusses prospects and implications for circular economy adoption in solid waste valorization in Nigeria.
