A Review of Solid Waste Management Strategies in Nigeria

The global population and increased urbanization have resulted in the increased production of municipal solid waste, thus, becoming a critical issue as a result of its poor management and inappropriate disposal. This is particularly the case of developing countries. This study assessed Solid Waste Management (SWM) strategies commonly adopted by different state waste management Authorities in Nigeria with a view to develop a sustainable roadmap for the management of solid waste in Nigeria. It assessed the Traditional Solid Waste Management Strategy (TSWMS), Waste Minimisation Strategy (WMS) as well as the Technological Strategy (TcS) employed, laying focus on their challenges and benefits. The study depended on a desktop study approach; hence, data were obtained from secondary data as the main source of information with emphasis on published journals, conference papers, newspaper posts and statutory reports from government agencies relevant to the current study. Results from the review showed that waste management across various parts of Nigeria is poor, interwoven with several challenges at all phase of the management process with little benefits recorded on alternative SWM strategy. The reason for the low success rate of some of this management strategies were noted as; increase in population, area covered, increase in urbanization and industrialization, tenure of government, over dependence on government authorities for waste management, finance and other factors of the environment. Although most waste authorities rely heavily on the TSWMS, WMS and the TcS showed a better and promising alternative strategy when inculcated into the already existing strategy. Based on this finding, a roadmap for the actualization of a sustainable integrated solid waste management strategy was recommended for adaptation and adoption by the Nigerian SWM Authorities and Agencies.

Potential for cleaner energy recovery and electricity generation from abattoir wastes in Nigeria

Energy recovery and electricity generation from abattoir wastes was investigated with the aim of combating both energy crises and environmental pollution problems. Anaerobic digestion was carried out in a two 10 L batch digesters for about 30 days under mesophilic condition. Biogas volume was measured by water displacement method at every 24 h interval. Based on the volume of biogas produced and its methane composition, electricity value of the produced biogas was estimated. Daily average and cumulative gas volumes of 0.00103 m3/kg VS (1.03 liters) and 0.0309 m3/kg VS (30.90 liters) were obtained respectively with 63.4% methane composition. The results suggest that 1040 MWh and 1664.6 MWh of electricity can be generated from biogas at low-end conversion efficiency of 25% and at high-end conversion efficiency respectively. The study concluded that waste to wealth technology, if appropriately explored is a viable solution to energy crises in Nigeria.

Biotransformation and oxidative stress responses in relation to tissue contaminant burden in Clarias gariepinus exposed to simulated leachate from a solid waste dumpsite in Calabar, Nigeria

In this study, we have investigated biotransformation and oxidative stress responses in relation to tissue contaminant burden in the African sharptooth catfish (Clarias gariepinus) exposed to simulated leachate from a solid waste dumpsite in Calabar, Nigeria. Fish were exposed to simulated leachate, diluted to 0:0 (negative control), 1:10, 1:50, 1:100 and phenanthrene (a PAH: 50 μg/L used as a positive control) for 3, 7 and 14 days. Hepatic transcripts for cat, sod1, gpx1, gr, gst, cyp1a, cyp2d3, and cyp27 were analyzed by real-time PCR, while enzymatic assays for ethoxyresorufin O-deethylase (EROD), buthoxyresorufin O-deethylase (BROD), methoxyresorufin O-deethylase (MROD), pentoxyresorufin O-deethylase (PROD), catalase (CAT), glutathione peroxidase (GPx), glutathione reductase (GR), glutathione S-transferase (GST), uridine diphospho-glucuronosyltransferase (UDPGT) and lipid peroxidase (LPO) were measured using standard methods. In addition, protein expression for CYP1A, CYP3A and metallotheionin (MT) were measured by immunoblotting. Fish muscle samples were analyzed for selected group of contaminants after 14 days exposure showing significantly high uptake of heavy metals (Cd, Hg and Pb), polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs), chlorophenols, organochlorine (OC) and organophosphate pesticides in exposed fish. We observed significant concentration- and time-specific increases in biotransformation and oxidative stress responses at transcript and functional (enzyme and protein) levels, that paralleled tissue contaminants bioaccumulation patterns, after exposure to the simulated leachates. Our results highlighted the potential environmental, wildlife and public health consequences from improper solid waste disposal. In addition, it also provides a scientific basis for local sensitization and inform legislative decisions and policy formulation towards sustainable environmental management of solid wastes in Nigeria and other developing countries.

Waste management authorities have adopted different strategies at different times in managing waste in Nigeria. In spite of the various efforts put in place, municipal solid waste remains one of the most conspicuous and repugnant environmental problems that threaten the Nigerian city. This paper examines the challenges and opportunities of Public-Private Partnerships (PPP) in residential solid waste management in Ibadan, Nigeria. Data for the study were obtained from the Oyo State Solid Waste Management Authority (OYOWMA). Findings revealed that the commonly-generated wastes were organic wastes and there existed a mismatch between waste generation and collection. Between 2012 and 2015, city waste managers collected and transported 2,411,145.78 metric tonnes of waste to the four dumpsites in Ibadan. The dumpsites’ locations were sub-optimal, surrounded by sprawling neighbourhoods due to inadequacy in urban planning and enforcement of development control. This has adverse effects on the well-being of residents. Municipal solid waste management is capital-intensive and the decline in budgetary allocations to waste management necessitated the PPP user-charges arrangement. This intervention notwithstanding, indiscriminate dumping of wastes continued to be cheap means of disposing of solid wastes, with implications for drainage system and flooding. Waste sorting, recycling and conversion should be given adequate consideration and the informal waste managers should be mainstreamed into the urban waste management architecture.    Key words: Private waste contractors, Oyo State Solid Waste Management Authority, residential solid waste, informal waste collectors, dumpsite, Ibadan. &nbsp

The Implementation of Biogas Production from Municipal Solid Waste in Nigeria

The deployment of clean energy systems has increased over the years as a result of the attendant effects of convectional fuel-based plants. A good set of goals, inclusive of clean and affordable energy initiative, have been set and implemented in many developing countries by the United Nations. However, the commitment to reduce greenhouse emission with clean energy technologies in Nigeria has faced several implementation challenges. This study presents a technical and economic feasibility analysis of an 8m 3 fixed-dome family biogas digester to replace the use of fuelwood in rural community households in selected states of the six geopolitical zones of Nigeria. Based on the economic analysis from the results, the use of biogas-digester is more economically viable with a quick return on investment, low maintenance cost, and availability of raw materials at little or no cost. The results also revealed other benefits such as avoided greenhouse gas (GHG) emission, reduced deforestation due to very low dependence on fuelwood, health benefits; eliminating hazardous particulate matter, fatigue, and health conditions for women and children as a result of long-distance travelled and hours spent fetching fuelwood. Additionally, the time wasted in collecting fuelwood can be reduced and maximized for other gainful and laudable activities such as learning. This paper recommends sustainable policies pertinent to the development and proliferation of biogas plants in rural communities of Nigeria. Following the 2013 economic rebasing, Nigeria happens to be the West African country with the largest economy. Considering the robustness of the country’s economy, public and private investments in clean technologies like biogas system, will not only help us meet household demands but also consolidate the energy sector, thereby opening many opportunities. Therefore, the significance of this study is that many households in rural populace would be empowered to meet their energy demand and reduce dependence on fuelwood. There are existing economic, regulatory and institutional frameworks to sustain this transformation, and Nigeria will witness the change it sets to achieve.

A Comparative Investigation of Groundwater Contamination in Typical Dumpsites and Cemetery Using Ert and Physicochemical Analysis of Water in Benin Metropolis, Nigeria

This paper investigated the comparative analysis of groundwater contamination in Third Cemetery and Costain Dumpsite in Benin Metropolis, South South of Nigeria, using Electrical Resistivity Tomography (ERT) and Physicochemical analysis of water. The implications of land utilization for burial of dead human bodies in the form of cemeteries, many cases associated with coffin and caskets used for interment of remains and the location of refuse dump have received no consideration in Nigeria. Interment of bodies in cemeteries and dumping of refuse in dumpsites remain widespread practice and the only alternative endpoint to dead bodies and disposal of wastes in Nigeria. In Nigeria, this practice had not been perceived as having a significant potential contaminant effect in the environment and especially the groundwater component as search of literature attracted no such study to the country. In Benin City and Nigeria in general, the major cemeteries and dumpsites are located close to human residential areas and virtually all the populace within this locality depends on groundwater as the primary water source for various domestic purposes. Res2Dinv was employed in both sites as the geophysical method. The investigation of cemeteries is always difficult and challenging task in geoforensic prospective. Most researchers assess the impact of interment on the environment by comparing study results from cemeteries with data from reference sites. This study is based on this premise. The 2-D Geological Models showed that both Third Cemetery and Costain Dumpsite contained leachate plumes of various degrees as indicated by the low resistivity values, which infiltrated into the groundwater. The values of Water Quality Index (WQI) of groundwater samples in Third Cemetery and Costain Dumpsite were found to be 13.40 and 21.58 respectively which indicated that the quality of water at both Third Cemetery and Costain Dumpsite were good for drinking and other domestic purposes though with some degrees of contamination.

Managing Medical Wastes During the Covid-19 Pandemic in Nigeria

A pandemic disease poses great threats to humans and apparently, leading to a global crisis and challenge on the health, economic and other sectors of human endeavour. In order to minimize the devastating effects from pandemics such as the novel corona virus, effective management of ever increasing medical waste is pertinent. Recently, Nigeria has been reporting increasing number of cases from Covid-19 with increasing pressure mounted on the Government, healthcare systems and the populace in entirety. Owing to the high rate of infection from the corona virus, a more sophisticated method of managing the generated infectious is pertinent to mitigate the effects of the infectious medical waste accruing to the environment. More emphasis in the spread and management of covid-19 in Nigeria is focused on establishing testing centres, treatment centres and isolation facilities with little attention or no attention towards establishment of a safe disposal facilities for the infectious waste generated. This study has assessed effective management strategies for covid-19 associated medical wastes in Nigeria. Data for the study was majorly descriptive and adapted from secondary source through the Nigeria Centre for Disease Control (NCDC). Investigations from the study carried out reveals that Nigeria's foremost Environmental Regulatory body has no officially assigned dumpsite across the country for medical waste. Furthermore, the tertiary healthcare facilities across Nigeria's states has no safe and proper facilities for disposal of infectious medical waste. Challenges such as the various lackadaisical attitude and negligence of the populace towards covid-19 pandemic as well as poor enforcement of guidelines on infectious medical waste. In addition, the study recommends based on the findings, the use of Personal Protective Equipment (PPE) by waste collectors and the involvement of relevant stakeholders in the creation of environmental department to be supervised by Environmental Health Officers in all hospitals as a measure to ensure effective enforcement of the guidelines on safe disposal of infectious medical waste.

Marketing of Palm Oil Wastes: Economic and Environmental Benefits in Nigeria

The palm oil industry provides means of livelihood to many people thus contributing substantially to the Nigerian economy. Wastes generated from the processing of palm oil often constitute environmental hazards. At present, there is strategic search for research, policy debates and agro-environmental schemes geared toward the conversion of waste to wealth in the industry. It is important that the wastes generated by palm oil processors be managed using technologically sound, economically viable and environmentally friendly techniques. The study investigated the financial and environmental benefits in the marketing of palm oil wastes. Data on waste disposal methods and revenue derivable from the marketing of palm oil wastes were collected from primary sources using structured questionnaire. Data obtained from these sources were analyzed with the use of descriptive statistical tools and correlation analysis. The result showed that the major type of palm oil waste generated was palm press fibre (PPF) (40%) and palm kernel shell (32%). Recycling of waste (36%) dominated the waste management methods, followed by the sale (30%), while the least was dumping method. Disposal of palm oil waste through organic recycling had positive effect (54%) on the environment. The sale of palm oil mill effluent had significant (p<0.05) and positive relationship with revenue generated by palm oil processors. The marketing of palm oil waste studied enhanced the income of palm oil processors and improved environmental quality respectively. We recommended the development of the emerging market for palm oil wastes in Nigeria.

The production of carbon black from the unripe peels of plantain (<i>Musa paradisiaca</i>) in Nigeria

Carbon black (CB) is an intensely black, finely divided form of amorphous carbon. It is usually obtained as soot from the partial combustion of hydrocarbons and has found many industrial uses such as reinforcing agents in automobile tires, black pigments printing ink, paint, carbon paper, etc. Although it can be obtained as a by-product of petroleum production, it can also be produced from indigenous materials of plant origin. This work demonstrated how CB can be obtained from the peels of unripe plantain. Seventy kilogram of wet peels of black plantain was collected from the local women, cut into smaller portions and sundried for seven days to obtained fifty three kilogram of the dried peels which were then carbonization by heating in an air-tight metal kiln for an hour. The carbonized peels were later pulverized and then filtered with sieve of mesh size 212um to give very fine filler particles of carbon black. The finished product was test run as a refill toner powder for HP Laser Jet Professional P 1606dn and using it to print some documents. The result of this work exhibited the implications for reusing plantain peels (a common solid waste in Nigeria) to produced CB. Keywords: Carbon black, Plantain peels, Toner powder, Musa paradisiaca

Viability of ‘Dilute and Attenuate’ Landfill as a Final Disposal Method for Solid Waste in Nigeria

The predominant disposal method of solid waste management in the world is landfilling while that of Nigeria remains open dumping and open burning. The aim of this study is to evaluate the viability of ‘Dilute and Attenuate’ landfill as a final disposal method for solid waste in Nigeria. A ‘dilute and attenuate’ landfill was evaluated by assessing groundwater and landfill gas. Water samples for laboratory tests were collected upstream and downstream of the landfill site. Laboratory tests are pH, Conductivity, biochemical oxygen demand (BOD), chemical oxygen demand (COD), suspended solids (SS), volatile suspended solids, ammonia and heavy metals. The landfill gas was assessed onsite from seven (7) gas sampling points across the landfill site using an infrared gas analyser. The presence of methane and carbon dioxide at all the gas sampling points except Cell D shows that the landfill has not reached full stabilization and therefore, has a mild potential to contaminate the surrounding. There is no significant difference between the values of pH, conductivity, COD, BOD and Ammonia of groundwater in the wells upstream and downstream of the landfill site the values generally within acceptable limits for potable water.

Experimental characterization of selected Nigerian lignocellulosic biomasses in bioethanol production

Experimental characterisation of five biomass wastes: corn cobs, cassava peels, rice husks, white yam peels and sugar cane bagasse based on proximate analysis and X-ray diffraction (XRD) analysis has been reported in this study due to their huge inherent potential for bioethanol production. XRD gave an indication of the presence of cellulose and carbon in the biomasses. Thermo-gravimetric analysis showed that the cellulose composition of the five biomasses is quite close, with sugar cane bagasse having the highest content of 39.8 wt % and cassava peels biomass presented the lowest content of 25.8 wt %. For each of the biomasses presented in this study, their cellulose content is in conformity with reported values from previous work on them. The results demonstrate that the collected lignocellulosic biomasses are a potential substrate for energy and bioethanol production which can constitute a huge market as the biomasses are sustainably produced as wastes in Nigeria.

Energy recovery from municipal solid waste in Nigeria and its economic and environmental implications

AbstractAn assessment of potential biomass resources in Nigeria for the production of methane and power generation is presented in this paper. Nigeria, as an underdeveloped and populous country, needs an uninterrupted source of energy. The country's energy problems have crippled large sectors of the economy. The percentage of people connected to the national grid is 40%. These 40% experience electricity supply failure on average 10–12 hours daily. Energy generation from municipal solid waste (MSW) is an effective MSW management strategy. Yearly waste generation has increased from 6,471 gigagrams (Gg) in 1959 to 26,600 Gg in 2015. This amount is projected to reach 36,250 Gg per year by 2030. Methane emission for 2015 was 491 Gg, and it is projected to reach 669 Gg in 2030. These values translate to 3.48 × 109 kilowatt hours (kWh) of electricity for 2015, with a projected 4.74 × 109 kWh by 2030. The revenue to be derived from the electricity that is generated could have been US$365.04 × 106 for 2015, and it is estimated that it will reach US$473.82 × 106 by 2030. It was found that methane emissions from MSW increased with time, and capturing this gas for energy production will lead to a sustainable waste management.

Assessment of Heavy Metal Pollution of Surface Soils from Scrapyards in Benin City, Nigeria

Scrap metals found in scrapyards accounts for a large proportion of municipal solid waste in Nigeria. They are a menace to the environment and pose potential health risk to nearby residents. T his study assessed the physicochemical quality and heavy meta l contamination of surface soils from selected scrapyards in Benin City, Nigeria. Surface soils were collected from 12 randomly selected scrapyards between February and April 2018. Physicochemical analyses were carried out using standard analytical methods , while heavy metal ( Fe, Cd, Zn, Cr, and Pb ) concentrations were determined using atomic absorption spectrophotometry. The physicochemical indicators showed values which ranged from 6.17 ± 1.17 to 7.81 ± 0.88, 335.00 ± 60.62 to 2467.33 ± 1708.95μS/cm and 2 .18 ± 0.39 to 44.27 ± 17.72 mg/kg for pH, electrical conductivity (EC) and nitrate ( NO - 3 ) respectively. The texture of the scrapyard soils was predominantly sand. The concentrations of the heavy metals in the scrapyard sites were significantly ( p < 0.05 ) higher than the control site. A strong positive correlation existed among the studied metals. The concentrations of heavy metals were above the WHO/FAO critical level of 100 mg/kg except for Cr and Cd. Contamination indexes of the scrapyard soils showed th at the soils samples from all the locations were highly contaminated with heavy metals. There is urgent need for evacuation of the scrap metal wastes from the scrapyards and enactment of appropriate legislations which prohibits the use of land in residenti al areas as scrapyards in the city to prevent likely health hazard

Households’ Perception of Financial Incentives in Endorsing Sustainable Waste Recycling in Nigeria

Recycling is viewed as a central aspect in sustainability and mainly as pro-environmental consumer behavior. The purpose of this study is to examine the perception of households on financial incentives in endorsing sustainable recycling for municipal solid waste in Nigeria. The study was conducted in the Shomolu Local Government Area, Lagos State, Nigeria. The study also covers drivers for household willingness to recycle municipal solid waste on environmental risk, behavioral economics, resource value, economic benefit, convenience, knowledge, legislation, and belief. The result from the study asserts the hypothesis that financial incentives for recycling are vital for reducing and managing municipal solid waste sustainably. The most important driver for household willingness to recycle municipal solid waste is the detrimental environmental impacts. A moderate to positive relationship exists between households’ perception of financial incentives for recycling and drivers for household willingness to recycle municipal solid waste. The study recommends adopting the extended producer responsibility (EPR) model, reverse vending options, amongst other approaches, in an effort to promote recycling culture among citizens and residents in Nigeria.

Re-Examining Hazardous Waste in Nigeria: Practical Possibilities within the United Nations System

Over several decades, Nigeria has still not been let off the hook for the leeching effects of environmental pollution, particularly that caused by ever-growing mountains of hazardous waste. From the harmful gases put into the atmosphere or the toxic waste released into water bodies and to the waste produced from our homes, the unchecked creation of hazardous waste continues to pose a threat not just to the health and lives of both present and future generations but also to economic growth and development as well as the enjoyment of basic human rights. This article aims at examining the major issues surrounding the unbridled production of hazardous waste in Nigeria as well as some practical possibilities within the United Nations system to put an end to the menace. In so doing, a doctrinal method of legal research is employed by conducting a qualitative content analysis of primary and secondary sources of materials. This article finds that in the absence of practical and innovative actions to stem the relentless growth in waste, the future of Nigeria's economic growth is hazy. It is concluded that if the country can take a proactive dive into the United Nations system by shifting the focus from ‘waste management’ to ‘resource management’ through legally binding instruments, there may soon be a pathway for Nigeria to create one of the most sustainable economies in the world. This article recommends a substantial step-change involving both national and local political players as well as the general public to implement more practical solutions to hazardous waste in Nigeria.

Genetic damage induced by electronic waste leachates and contaminated underground water in two prokaryotic systems

The inappropriate and unsafe management practices related to disposal and recycling of electronic wastes in Nigeria has led to environmental and underground water contamination. Reports on the level and type of contamination as well as the possible DNA damage effects of this contamination are insufficient. This study evaluated the DNA damaging potential of e-waste simulated and raw leachates, and its contaminated underground water using the SOS chromotest on Escherichia coli PQ37 and the Ames Salmonella fluctuation test on Salmonella typhimurium strains TA98 and TA100, without and with metabolic activation. Physico-chemical parameters of the samples were also analyzed. The result of the Ames test showed induction of base pair substitution and frameshift mutation by the test samples. However, the TA100 was the more responsive strain for the three samples in terms of mutagenic index in the absence and presence of metabolic activation. The SOS chromotest results were in agreement with those of the Ames Salmonella fluctuation test. Nevertheless, the E. coli PQ37 system was slightly more sensitive than the Salmonella assay for detecting genotoxins in the tested samples. Lead, cadmium, manganese, copper, nickel, chromium, arsenic, and zinc contents analyzed in the samples were believed to play a significant role in the observed DNA damage in the microbial assays. The results of this study showed that e-waste simulated and raw leachates, and its contaminated underground water are of potential mutagenic and genotoxic risks to the exposed human populace.

Review on the Environmental Impacts of Municipal Solid Waste in Nigeria: Challenges and Prospects

Review on the Environmental Impacts of Municipal Solid Waste in Nigeria: Challenges and Prospects

State-level assessment of the waste-to-energy potential (via incineration) of municipal solid wastes in Nigeria

The quest for reliable and adequate power supply in Nigeria has brought about a surge of interest in renewable energy generation, particularly from wind, solar, hydro and biomass resources including municipal solid waste. Waste-derived energy raises unique interest because of the magnitude of benefits to environmental protection and socio-economic advancement. The successful operation of Waste-to Energy (WtE) facilities in Nigeria requires continuous supply of solid waste and enabling environment amongst other factors. This study conducted a state-level assessment of the WtE potential of municipal solid waste (MSW) in Nigeria. Our findings show that the electricity generation potential for the different states in Nigeria varied from 31 to 205 MW, depending on state’s waste generation capacity. The country’s annual electricity generation potential from MSW was estimated to be 26,744 GWh/year, with 89% of the states having sufficient generation capacity at minimum regulatory electricity generation requirement of 50 MW. But, based on current realities such as poor collection efficiencies, Nigeria’s exploitable WtE capacity from MSW was below 3800 GWh/year, with all the states having less than 50 MW capacity. On-site power generation such as dedicated power station for industrial estates and corporate users can be a feasible form of distributing energy generated from WtE facilities. The outcomes of this study are important in informing the siting of WtE facilities in Nigeria and for enabling policy framework.

THE PROSPECT OF MINIMISING PRODUCTION FLOW WASTE ON CONSTRUCTION SITES IN NIGERIA THROUGH THE LAST PLANNER® SYSTEM

Poor performance of construction projects is a re-occurring problem in Nigeria. Production flow waste (ranging from waiting time, material handling and over- production, among others) may be partly responsible for this problem. Meanwhile, very little is known about the role of the Last Planner System (LPS) in minimising production flow waste in Nigeria. The current study examines the manifestation of production flow wastes on Nigerian construction sites, identifies current construction practices that bear resemblance to the LPS, and finally, examines the prospects of the LPS concepts in minimising production flow waste in the corresponding construction projects. A mixed research design that uses a quantitative cross-sectional survey and qualitative-exploratory approach was used in collecting data from construction professionals based in Nigeria. Fifty-one survey responses were received and 10 interviews were conducted. The study reveals various incidences and contributory factors to production flow waste, with the long approval process being the most prevalent. It also identifies current practices that are similar to the LPS practices. The prospect of the LPS in production flow waste management for improved productivity is also explored. The study concludes that the LPS concept has the potential for minimising production flow waste in the construction process and improving productivity in the Nigeria construction industry.
