“…The composition of the waste also varies with location, and the composition of municipal solid waste in some Nigerian cities has been compiled in different studies [247,250,251]. Generally, from all characterizations, it is observed that the organic constituent of the wastes has the highest contribution.…”

An Assessment of Potential Resources for Biomass Energy in Nigeria

Nigeria is a developing country with an insufficient supply of energy to meet the continuously growing demand. However, there are several biomass resources available within the country. This paper presents a desk review, which investigates the potential resources for biomass energy generation within the country. Energy policies to aid biomass use as an energy source within the country were also reviewed. Biomass resources identified within Nigeria include forest residues, agricultural residues, human and animal wastes, aquatic biomass, and energy crops. However, several of the resources, particularly agricultural residues, have competing uses, such as livestock feed and soil rejuvenation. An estimation of the technical energy potential of the biomass resources revealed that about 2.33 EJ could be generated from the available resources in Nigeria. Agricultural residues have an energy potential of about 1.09 EJ, with cassava, maize, oil palm, plantain, rice, and sorghum being the major contributors. Animal wastes, municipal solid waste, and forest residues have energy potentials of 0.65, 0.11, and 0.05 EJ, respectively. The potentials of wood fuel and charcoal are 0.38 and 0.05 EJ, respectively. The study found that despite the available potential and existing policies, not much has been done in the implementation of large-scale bioenergy within the country. However, there has been laboratory and research-scale investigations. The review suggests that more policies and stronger enforcement will aid bioenergy development within the country. From the review, it has been suggested that the agricultural sector needs to be developed to generate more biomass resources. More research, development, and implementation have to be carried out on biomass resources and bioenergy generation processes. The production of non-edible energy crops in marginal lands should also be considered prime to the development of bioenergy within the country.

“…The generation of electricity from LFG and feeding into the distribution grid can reduce the constraints on coal-fired power stations, thus reducing CO 2 emission and other pollutants that contribute to poor air quality and climate change (Hadidi and Omer, 2017;Rajaram et al, 2011;Stehlik, 2016). LFG has been proven to be a reliable and sustainable energy resource that can significantly reduce GHG emissions, which is in line with the United Nations Framework Convention on Climate Change (UNFCCC) 1997 Kyoto Protocol (Bogner et al, 2008;Yusuf et al, 2019). Relative to conventional fuels, LFG emits water and less harmful CO 2 as by-products of combustion and has a high calorific value of 17 megajoules cubic −1 metre (Purmessur and Surroop, 2019;Stehlík, 2009).…”

“…The slow adoption of LFGE projects is attributed to inadequate policies, lack of data on waste, poor municipal solid waste management (MSWM), high implementation and maintenance costs, limited knowledge, paucity of research and development (R&D) (Couth and Trois, 2010; Dlamini et al, 2019; Yusuf et al, 2019). Due to the aforementioned challenges, MSW management remains a challenge in many developing countries, particularly SSA countries; presenting an environmental and public health challenge that has existed for the past 20 years (Cudjoe and Han, 2021; Mmereki, 2018; Ofori-Boateng et al, 2013).…”

“…For instance, the Hulene dumpsite in Maputo, Mozambique is regarded as the biggest open dump (dos Muchangos and Tokai, 2020). Many SSA countries, lack data on the composition and generation of MSW, that are important in determining the potential for implementing LFGE projects (Yusuf et al, 2019).…”

Landfill gas to energy (LFGE) projects were implemented in the Republic of South Africa (RSA) to diversify the energy mix and transition to a green economy. This study provides an overview of the status of LFGE in RSA and identifies major factors that inhibit the adoption and utilization of this technology, using existing data from 2010–2020 from electronic databases, namely, ScienceDirect, Taylor & Francis, Google Scholar, Sage Open, Springer Link, Sabinet, and IEEE Xplore, and using a combination of keywords and Boolean functions. This study revealed that, although RSA has made significant progress in the adoption and utilization of landfill gas (LFG) through the seventeen (17) planned LFGE projects, only six (6) are operational and generate 15 MW of electricity supplied to the local grid in the KwaZulu-Natal, Western Cape, and Gauteng Province. The waste-to-energy (WtE) sources such as LFGE are not given priority, and the country continues to invest in coal-fired power stations, owing to the abundance, availability, and low cost of coal reserves, which will supply coal for the next 200 years. The study identified factors inhibiting LGFE projects in RSA, which included the lack of sanitary landfill sites, LFG monitoring, funding, skills, research, and development. Potential LFGE in RSA is evident, however, except for limited processing facilities, economic investment, and public awareness. Suggestions for further research on the techno-economic and policy assessments are provided in the study. This study contributes to synthesizing evidence of the status of LFGE, insights on state-of-the-art technologies of WtE and the associated challenges in the waste management sector, identifying the potential for LFGE, and LFGE in the circular economy, and building a foundation for future research on WtE such as LFGE. Moreover, it also offers a reference for policymakers, decision-makers, researchers in the waste management sector on the technologies of WtE, LFGE, and potential to reduce waste generated.
