“…Consequently, these blends with lignite revealed a high carbon and oxygen content. Ding et al (2021) concluded that high oxygen concentration improves co-combustion performance. The results concerning the blends are in agreement with literature findings (Iordanidis et al 2018;Azam et al 2020b).…”

“…Perera et al (2021) prepared a review paper regarding the modeling of the thermochemical conversion of several kinds of biomass waste. Ding et al (2021) studied the cocombustion behavior of municipal solid waste and lowrank coal semi-coke in air or oxygen/carbon dioxide atmosphere. A methodology for the techno-economic analysis of MSW systems based on a social cost-benefit analysis with an evaluation of externalities was performed by Medina-Mijangos et al (2021).…”

Recently, coal power plants across Europe have been reopened. Alternative fuels are needed for energy autonomy purposes, for a smoother transition to the post-lignite era and for sustainable development. In this work, different categories of municipal solid wastes (MSW) and their blends with lignite were studied for their potential use as alternative fuels. Seventeen samples were studied using several techniques: gross calorific value (GCV), proximate analysis, ultimate analysis, ion chromatography, ash elemental analysis, thermogravimetric analysis, kinetic modeling and thermodynamic analysis. A determination of empirical chemical formulas was performed. Slagging/fouling potential was evaluated with various indices including modified indices that take into account ash production and GCV. Maximum emission factors were calculated and defined per produced MJ. Also, an environmental footprint index was developed regarding the environmental impact of solid wastes. The GCV experimental results were compared with those of twenty different empirical models. Moreover, several case studies were performed to evaluate the potential of covering the energy demands, with combustion of MSW, in Greece and Europe. The results showed that MSW as a primary/secondary fuel is an attractive solution considering the fact that it boasts better characteristics in comparison with lignite. Moreover, the environmental footprint index (EFIsw) of the MSW revealed a much smaller environmental impact. The high N content is not always translated to high emissions if NO is expressed per produced MJ (gNO/MJ). In addition, MSW can also be used as a significant contributor in covering energy demands regarding the energy recovery potential. Graphical abstract

“…The total amount of municipal solid waste (MSW) in China reached 191.4 million tons in 2015 [1], and production is predicted to increase to 480 million tons in 2030 as a result of economic development and a growing population [2][3][4]. This has caused very serious environmental and social problems.…”

An integrated CO2/O2 co-gasification system of municipal solid waste (MSW) and bituminous coal (BC) with CO2 capture was developed and simulated by the Aspen plus, which mainly consisted of three processes: air separation unit, co-gasification system, and CO2 absorption unit. In addition, raw syngas composition, cold gas efficiency (CGE), and overall energy efficiency (OEE) of the entail system were evaluated in detail with respect to the main operating parameters (gasification temperature, T; oxygen equivalence ratio, Ro; mole of CO2 to carbon ratio, Rc; and the MSW blending ratio, RM). The results indicated that the addition of BC improved the gasification of MSW. Higher gasification temperature increased CGE and OEE. Increasing the Rc ratio led to the decrease of H2 mole fraction due to the enhanced reverse water-gas shift reaction. In addition, the CGE and OEE of the system decreased with increasing RM. From the analyses of the parameters, the most optimal operating conditions were set as T = 900 °C, Ro = 0.2, Rc = 0.5, and RM = 0.6, and the corresponding OEE of the system reached 0.57. The system can achieve a large processing capacity of MSW at the cost of the efficiency loss of this condition.
