Municipal solid waste management has emerged as one of the greatest challenges facing environmental protection agencies in developing countries. This study presents the current solid waste management practices and problems in Nigeria. Solid waste management is characterized by inefficient collection methods, insufficient coverage of the collection system and improper disposal. The waste density ranged from 280 to 370 kg/m3 and the waste generation rates ranged from 0.44 to 0.66 kg/capita/day. The common constraints faced environmental agencies include lack of institutional arrangement, insufficient financial resources, absence of bylaws and standards, inflexible work schedules, insufficient information on quantity and composition of waste, and inappropriate technology. The study suggested study of institutional, political, social, financial, economic and technical aspects of municipal solid waste management in order to achieve sustainable and effective solid waste management in Nigeria.

    • "Saeed et al. (2009) however, argue that landfills have various environmental impacts. The environmental impacts of landfills are very costly especially in terms of health implications for those living around the landfill sites (Ogwueleka, 2009). The impacts of landfills may vary from one region to another depending on the types and composition of the wastes on the landfill and the terrains of an area (Suberu et al., 2012). "

    • "Nsukka metropolis is one of the most populated urban centres in Enugu State, Nigeria with a 2009 population estimate of one hundred thousand , seven hundred (100,700) [11], and growing annually at an estimated rate of 3.0% and generating 0.39kg of municipal solid waste per person per day [12]. Nsukka is equally experiencing significant waste-related environmental problems. "

    ABSTRACT: The continued concerns over energy prices, increase in population, and climate change issues have caused a need for alternative and new energy sources. Wastes are generally accepted as a renewable energy resource. With the growing demerits of fossil fuels, its finitude and its negative impact on the environment and public health, renewable energy is becoming a favoured emerging alternative. For over a millennium anaerobic digestion (AD) has been employed in treating organic waste (biomass). Since organic wastes are always available and unavoidable too, anaerobic digestion provides an efficient means of converting organic waste to profitable resources. Nsukka metropolis generates a large tonnage of municipal solid waste (MSW) per annum. This in turn has the potential of yielding biogas which is useful for heating and other domestic purposes. In this research, the potential of generating biogas (hence methane) from biodegradable components of municipal solid waste (MSW) found in Nsukka metropolis was assessed. Samples of MSW obtained from Anglican road dumpsite were characterized and experiments were carried out using a 32-litre bio-digester at the National Centre for Energy Research and development (NCERD) to obtain the daily biogas yield.

    ABSTRACT: An assessment of the coastal dumpsites and their impacts on shrimp mortality in the Lagos lagoon was investigated. The study involved a census of dumpsites in the major sections of the coastline associated with anthropogenic activities, followed by specific bioassay to determine the acute toxicity of leachates from one of the dump sites. Our investigations revealed that there were 8 major dumping localities with approximately 28 dumpsites generated mostly by deliberate efforts and in some cases by tidal activities which litter the coastline. The major dumping localities were Abule Eledu, Ebute Ilaje, Oworonshoki, Ibese, Offin, Off Ozumba Mbadiwe Road, Iddo and Okobaba. The largest number of dumpsites was recorded at Owonronshoki and Ibeshe, each with 19% of the total dumps while the least number was recorded at Off Ozumba Mbadiwe Road (4%). The major waste categories include fabrics (worn clothes), plastics, wood and wood shavings, glass, metallic objects as well as paper and packaging materials. The acute toxicity assessment of leachates from a dumpsite at Abule Eledu indicated moderate toxicity to brackish water shrimps (Palaemonetes africanus) with 96 hr LC50 value of 93.59% (935.9ml/L). The leachate was found to be high on biological and chemical oxygen demand, conductivity, total dissolved solids, nitrate and sulphate. The findings from this study indicate widespread and unregulated practice of coastal solid waste dumping with potential effects on water quality and biota. The need for improved waste management system in the City of Lagos was discussed. © JASEM
