“…The mean value of each MSW component and the weight of the waste sample with energy potential are also tabulated in percentages. The output from SowaCLINK software on the heating value and total combustion energy in KJ/kg of the characterized MSW is within an acceptable range (Sincero and Sincero, 1996;Rominiyi et al, 2017;Oladejo et al, 2020).…”

Municipal solid waste constitutes environmental challenges globally, especially in developing countries, due to increasing waste generation, population growth, inadequate infrastructure, lack of data and poor planning. This study aims to conduct a comprehensive waste audit on the municipal solid waste generated in Aba, a metropolis in southeastern Nigeria. Aba is a commercial city considered the messiest because of the massive municipal solid waste generation and poor management. The study investigated the energy potential and waste regeneration. Municipal solid waste data was sought to provide insight into the quantity and composition of municipal solid waste. The methodology was site-based, in line with the standard test method for determining unprocessed municipal solid waste (ASTM-D5231-92) and SowaCLINK software, a computer-based environmental application, was used for characterization. Linear extrapolation was adopted to quantify the rate of municipal solid waste generated. The geometric mean was applied to forecast the area’s population for a 10-year design period. The chemical elements of the characterized municipal solid waste were utilized based on the ASTM-D5291 standard for municipal solid waste thermochemical conversion, and the high and low heating values were analyzed. The outcomes provided energy recovery potential, the electrical power potential, and the power to the grid of electrical power of the municipal solid waste. The results obtained were 0.7813 kg/p/d and 490,268 t/y for a population of 1,719,185 persons. The percentage of the municipal solid waste components with energy potential was 71%, comprising 48% combustible and 23% organic components on average. The high heating value computed was 176.5 MJ/kg, and the low heating value was 14 MJ/kg. The energy recovery potential was 3,709,463 MWh, the electrical power potential was 38,680 MW, and the power to the grid was 26.1 MW daily. The research reveals a promising direction in transitioning from the linear economy of municipal solid waste management toward implementing an integrated sustainable municipal solid waste management based on the circular economy model. The study recommends adopting detailed steps to proffer solutions to the environmental challenges associated with municipal solid waste in most low-middle-income countries to achieve sustainable municipal solid waste management while generating electricity and bio-fertilizers through incineration and anaerobic digestion.

“…Presently, the National energy supplies are almost entirely dependent on fossil fuels and firewood which are depleting fast. Wastes are important source of energy presently used in the generation of electricity and at the same time making the environment clean [54]. The heating value of waste is a measure of the energy released when it is burned [55].…”

“…The heating value of waste is a measure of the energy released when it is burned [55]. This energy content can be determined by: using a full scale boiler as a calorimeter, using a laboratory bomb calorimeter of any type, calculation (using empirical formulas) if the elemental composition is known [54].…”

The management of MSW is a major concern in several cities of developing countries due to its public health and environmental sustainability implications. This paper thus presents an overview of the current solid waste management practices and problems in some selected states in Nigeria. In addition to the comprehensive review of MSW generation, its characterization, collection, and treatment options in the considered states, an attempt was made to evaluate the major waste–to–energy indicators such as calorific values and energy (electricity) recovery potential. The legislations in place at the federal level to maintain healthy environment is also lucidly presented. An estimated electricity recovery potential in the range of 48.31 to 933.69 MW with a total of about 2600MW from six states was established. Evidences from literature suggested that the existing solid waste management system is inefficient due to uncoordinated and properly planned waste management system. This paper concludes that the thermochemical conversion of waste-to-energy into electricity is a feasible option in Nigeria, although this might require the input of additional quantity of fuel to initiate combustion since the lower heating values of the considered MSW fall below the optimum stipulated by World bank.

“…The specific energy content of the wood waste and charcoal are 16,795.96 kJ/kg, charcoal 18,711.70 kJ/kg respectively [9]. It can however be converted to bitumen or heavy oil due to the presence of cellulose in it by processing it with water, sodium carbonate and a gas rich in carbon (ii) oxide (CO) at a temperature of 250˚C -400˚C [5].…”

Sawdust which is basically considered as a timber-industrial waste that pollutes the environment can become a valuable commodity which is considered in three ways: Manufacturing, Energy and Agricultural utilization. The sawdust is burnt in an updraft gasifier under a limited supply of air to obtain producer gas which is carbon II oxide and hydrogen as main components. The sawdust and other biomass materials are mixed in certain proportions, then bound together and palletized to a small blocks called briquettes. The material was also considered to be composted by mixing it with animal digestion or wood ashes and calcium carbonate to form fertilizers. The sawdust and wood shavings can be used for particle board as well as oil production.
