Innovative Sustainable Solid Waste Management in Nigeria

Abstract

Problems associated with solid waste management (SWM) have proved to be complex in origin and in solution. In Nigeria SWM is characterized by ineffi cient collection methods, insuffi cient coverage of the collection system and improper disposal of solid waste. This chapter reviews the current status of SWM in Nigeria. For SWM to be sustainable in Nigeria a greater fi nancial investment needs to be made, possibly including provision through local rates and taxes. In addition, appropriate technologies in line with the nature of garbage generated need to be explored. Finally the effort and role played by the informal sector in SWM in Nigeria needs to be recognised, but there is urgent need for this sector to be formalized so that its role can be geared towards achieving sustainability. Keywords IntroductionThe Nigerian population is growing at an alarming rate Statistics show that the population growth rate of Nigeria as at 1991 was 3.0 % per annum with an urban growth rate of about 5.5 % per annum. The average waste generation rate is put at 0.49 kg per day (Adewole 2009 ). The volume and rate of waste generated is always

Selection of Suitable Landfill Site for Waste Disposal in Ilorin Metropolis Using Geographical Information System

“…Landfills have been acknowledged as an appropriate method of organized solid waste disposal in urban areas. However, many countries are yet to adopt the strategy because of the technical expertise required in the design, operation, and monitoring process that will ensure compliance with environmental regulations [8,9,10,11]. Additionally, the increasing population densities and its resultant of less land availability for siting landfills coupled with environmental health concerns, are also difficulties to overcome.…”

Site Suitability Analysis for Landfill in an Industrial Area in Nigeria

“…Landfills have been acknowledged as an appropriate method of organised solid waste disposal in urban areas (Ebistu & Minale, 2013;Zadawa et al, 2015;Osei et al, 2016;Jibril et al, 2017;Ezeudu, 2020). However, many countries are yet to adopt the strategy because of the technical expertise required in the design, operation and monitoring that will ensure compliance with environmental regulations.…”

“…This includes ensuring that existing and potential landfill occupiers are aware of the risks landfill poses to the quality of air, water and land resources (FEPA 1999;EPA 2006;Usman 2017). Therefore, the landfill occupiers are responsible for the management of the risks in the most effective way possible (Zadawa et al, 2015;Sridhar, 2017;Suleiman, 2019). The guideline stressed that selection of a landfill cannot be confirmed prior to completion of feasibility study and Environmental Impact Assessment (EIA) of the site.…”
