“…It is well known that while low-income areas usually produce more organic material, which generally means a high moisture content (60–75%), high-income areas produce relatively more inorganic wastes, which generally means low moisture content (20–30%). In addition, the average energy content of MSW is reported to be between 9.0 and 20.0 MJ kg −1 of dry waste (Franjo et al, 1992; World Bank, 1999). While the lower calorific value was reported for unprocessed waste, the higher was reported for components of MSWs separated in recycling activities.…”

Baling technology is a preferred method for temporary storage of municipal solid waste (MSW) prior to final disposal. If incineration is intended for final disposal of the bales, the energy content of the baled MSW gains importance. In this study, nine cylindrical bales containing a mix of different waste materials were constructed and several parameters, including total carbon (TC), total organic carbon (TOC), total Kjeldahl nitrogen, moisture content, loss on ignition, gross calorific value and net calorific value (NCV) were determined before the baling and at the end of 10 months of storage. In addition, the relationships between the waste materials and the energy contents of the bales were investigated by the bivariate correlation analyses. At the end, linear regression models were developed in order to forecast the decrease of energy content during storage. While the NCVs of the waste materials before the baling ranged between 6.2 and 23.7 MJ kg(-1) dry basis, they ranged from 1.0 to 16.4 MJ kg(-1) dry basis at the end of the storage period. Moreover, food wastes exhibited the highest negative correlation with NCVs, whereas plastics have significant positive correlation with both NCVs and TCs. Similarly, TOCs and carbon/nitrogen ratios decreased with the increase in food amounts inside the bales. In addition, textile, wood and yard wastes increase the energy content of the bales slightly over the storage period.

“…The moisture content of each category, vital for energy content and gasification, was also measured. The waste was also subjected to laboratory analysis to determine calorific value, volatile matter, ash content, and chemical composition, crucial for SRF conversion [26][27][28][29][30][31][32].…”

The management of municipal solid waste presents significant challenges globally. This study investigates the potential of an integrated waste-to-energy system based on circulating fluidized bed gasification technology to address these challenges, while also contributing to renewable energy generation. Using a MATLAB-based simulation model, the study determines the optimal operational parameters for various units within the system, including waste processing, gasification, ash handling, syngas treatment, and emission control. The proposed waste-to-energy system demonstrates a remarkable energy efficiency of 70% under these optimal conditions, notably outperforming conventional waste-to-energy technologies. Sensitivity and uncertainty analyses reveal that waste composition, gasification temperature, and the oxygen-to-solid recovered fuel ratio are key determinants of the system’s output and performance. The system’s performance remained robust despite variations in these parameters, underscoring its potential as a reliable solution for waste management and energy generation. While the findings are promising, future research should focus on comprehensive lifecycle assessment and consider regional factors for practical implementation. This study contributes to the ongoing development of efficient waste-to-energy systems and highlights their potential in promising sustainable waste management and renewable energy production.

“…The calorific value is classified into the gcV and NcV. gcV is described as the quantity of heat generated by a complete combustion of a unit mass of sample in air or oxygen, such that the product of combustion cooled down to the room temperature and remains in liquid form [26]. however, NcV is the net heat produced when a unit mass of the sample is completely burnt in air or oxygen, such that the product of combustion can escape as steam.…”

currently, Abuja, the capital of Nigeria, is experiencing an exponential increase in municipal solid waste (mSW) generation due to its rapid population growth, level of development, and its socioeconomic status among others. moreover, mSW is an overburden to the Abuja environment in terms of its management and health risk to the inhabitants. however, mSW is utilized by some countries as fuel for energy generation through the waste to energy (WTE) approach. In view of this, the study aims at assessing the mSW in Abuja as a potential resource for electrical power generation and distribution. This study is focused on incineration with energy recovery as an immediate solution for mSW reduction, and a supplementary answer to erratic electric power supply to the people. The proximate and ultimate analyses in combination with the modified Dulong equation were employed to determine the gross calorific value (gcV). results showed that the gcV was evaluated as 9,085 kcal/kg and the net calorific value (NcV) was evaluated as 9,067 kcal/kg. furthermore, the power generation potential was enumerated using 10 and 50 tons of combustible mSW to arrive at 966 kW and 4,832 kW, respectively.
