“…Transesterification is a process in which the fat fraction of food waste, especially used cooking oils and animal fats, are transformed into biodiesel [30]. During this physicochemical process, triglyceride molecules react with alcohol (methanol, for instance) in the presence of acid or base catalysts to produce biodiesel as the main product and glycerol as a by-product [31].…”

Municipal solid waste (MSW) in the Accra region of Ghana has created the need for innovative ways to deal with waste management crises facing the city. The goal of this study is to use the analytical hierarchy process (AHP) to select an appropriate waste-to-energy (WtE) technology for Accra. The AHP methodology is used to assess four WtE technologies, namely landfill biogas, incineration, anaerobic digestion, and aerobic composting. Three main criteria and nine sub-criteria are identified for pair-wise comparison and assessed by 10 experts. The results show that incineration is the most preferred technology, followed by anaerobic digestion and aerobic digestion, with landfilled gas being the least preferred technology. Stakeholders in waste management development in Ghana can utilize the findings of the study to develop implementation strategies for capacity and institutional capabilities for both thermochemical and biochemical processes in the country.

“…After the waste is burned, bottom ash is generated, and it must be cleaned up regularly. e incinerator is divided into a grate furnace, circulating fluidized bed furnace, and grate furnace with different incineration methods [53,54]. Waste incineration power generation technology also has two types of equipment, waste heat boilers and steam turbine generators.…”

Municipal solid waste incineration (MSWI) has been widely used due to its benefits in reducing waste and recovering energy. However, MSWI fly ash and bottom ash are increasing rapidly, causing harm to human health and the environment. This paper discussed the production process, physical and chemical properties, leaching properties, pretreatment methods, and applications of fly ash and bottom ash. By summarizing the previous literature, it is found that MSWI fly ash and bottom ash have mechanical properties similar to natural aggregate. Many beneficial attempts have been made in cement concrete aggregates, ceramic raw materials, and highway engineering materials. Due to concerns about the leaching of heavy metals in fly ash, its application in highway engineering is limited. The application of bottom ash in asphalt pavement is rare because of the side effect on the performance of asphalt mixture. Considering the solidification effect of cement on heavy metals and the low cost of fly ash and bottom ash, the application in cement-stabilized macadam base has broad application prospects. This is beneficial to reduce the construction cost and promote the process of waste incineration, especially in developing countries.

“…A variety of eco-friendly technologies have been proposed in the current era for thermal conversions and to reduce greenhouse emissions effectively [3][4]. Utilization of low-grade heat from industrial waste, solar plants, geothermal energy, municipal solid waste into energy or other thermodynamic cycles is well-known and most promising ideas to increase the system performance [5][6]. The power cycle employed at supercritical temperature and pressure (S-CO2 power cycle) is gaining more interest in scientists as modern technology with versatile applications [7][8].…”
