A Review on the Current Status of Municipal Solid Waste Management in Nigeria: Problems and Solutions

Abstract

The management of MSW is a major concern in several cities of developing countries due to its public health and environmental sustainability implications. This paper thus presents an overview of the current solid waste management practices and problems in some selected states in Nigeria. In addition to the comprehensive review of MSW generation, its characterization, collection, and treatment options in the considered states, an attempt was made to evaluate the major waste–to–energy indicators such as calorific values and energy (electricity) recovery potential. The legislations in place at the federal level to maintain healthy environment is also lucidly presented. An estimated electricity recovery potential in the range of 48.31 to 933.69 MW with a total of about 2600MW from six states was established. Evidences from literature suggested that the existing solid waste management system is inefficient due to uncoordinated and properly planned waste management system. This paper concludes that the thermochemical conversion of waste-to-energy into electricity is a feasible option in Nigeria, although this might require the input of additional quantity of fuel to initiate combustion since the lower heating values of the considered MSW fall below the optimum stipulated by World bank.

Sustainable cities through household waste management: an unexplored approach to challenges confronting private solid waste management

“…In Nigeria, Sridhar et al (2017) (Salami et al, 2018). In Benin City and environs, the MEPU is the regulatory ministry obligated to manage the environment on behalf of the Edo State Government.…”

“…It is because the government agencies feel that urban SWM is the sole responsibility of the government. Salami et al (2018) found that the amount of waste generated across Nigeria's cities has increased, but the management strategies are inadequate. For example, many of the states agreed to create dumpsites as the best available option.…”

“…With the volume of research on SWM such as Cobbinah et al (2017), Nwachukwu et al (2017), Ike et al (2018), Salami et al (2018), among others, only a few such as Afon (2007), Longe et al (2009) and Olukanni and Nwafor (2019) have worked in the direction of private SWM. Afon (2007) evaluated the role of the "Barro boys" in the informal sector in urban solid waste management in Mushin and Kosofe.…”

Challenges of SWM Hierarchy System: The Stakeholders New Saga in Perspectives

“…The production of dangerous chemical wastes by cities, such as hospitals and factories, which now causes breathing issues and early deaths, is another recent development in MSWM [3]. Nigeria has recently emerged as a market for recycling, despite the fact that recycling has not met the required standards [4]. Poor MSW management at landfill sites frequently draws animals, rodents, mosquitoes, vultures, and scavengers, which could have a negative impact on front-line workers' health or even result in their demise [1].…”

The Potentials of Kyanite Particles and Coconut Shell Ash as Strengthener in Aluminum Alloy Composite for Automobile Brake Disc

“…These wastes include: cartons, papers, animals bones, plastics, aluminium plates, nylon bags, ceramics, vegetable stems, electronics, computers, photocopiers, aluminium cans, etc. Nigeria is the biggest contributors to solid waste in Africa with an estimated 32 million tons per year [8] [9] [10] [11] [12]. Coconut shell wastes are produced in large quantity in most tropical countries worldwide as Coconut forms a regular part of the human diets and other uses: food, drinks, oil, decorations, charcoal, cosmetics, etc.…”
