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

Abstract

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 -205 MW, depending on state's waste generation capacity. The country's annual electricity generation potential from MSW was estimated to be 26744 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.

A Review of Effectiveness of Construction Waste Minimization Practices in Bauchi State, Nigeria

“…According to [20] and [22], it was disagree that the findings of [12], that waste minimization in construction site can reduce environmental hazard posted by neighbourhood but this assertion is contradicted [6,10], because recent research conducted in many States of the federation agree that construction site waste can cause diseases to the environment [1,11]. It is agree that environment is polluted by waste generated from construction sites in many cities in Nigeria [21], but [4] in their study stressed that environmental pollution is cause majorly by other household and industrial waste, even though, construction waste make large volume of this garbage. Similarly, studies have contributed to the main area of concerned in minimizing construction waste in many part of Nigeria most especially Bauchi State.…”

Assessment of Government Incentives for Energy from Waste in Colombia

“…Thermochemical treatment methods are widely preferred due to the substantial reduction of waste volume, the destruction of pollutants, and the opportunity they offer to recover materials and chemical products. The most commonly-used thermochemical treatment is incineration; however, newer technologies, such as pyrolysis and gasification, are more efficient and emit less greenhouse gases [4,16]. Biochemical conversion processes include recovery of gas from landfills, anaerobic digestion, fermentation, and anaerobic composting [7,17].…”

“…Currently, companies responsible for waste management do not take full advantage of the energy potential there is in waste. However, said recovery is known to be possible with thermal conversion technologies (incineration and gasification) and bioconversion (landfill gas and anaerobic digestion), which have been successful in some countries [4,5]. These solutions, besides enabling optimal waste management, contribute to meet the energy demands of the country.…”

“…The work in [4] assessed the WTE potential of municipal solid waste (MSW) throughout Nigeria. The country's annual electricity generation potential from MSW was estimated to be 26,744 GWh/year.…”

Electricity generation potential from solid waste in three Colombian municipalities

“…In [14], the authors present an overview of energy (electricity) generation potential from solid waste in mega-cities of Bangladesh. In [15], the WTE potential of municipal solid waste (MSW) was assessed throughout Nigeria using the population growth rate factor and the boiler, steam and overall efficiencies for calculating the exploitable energy potential. Other authors [16] evaluated the potential contribution of WTE facilities to the total Saudi peak power demand until 2032 by means of a quantitative analysis of six large cities.…”
