Summary: This study utilized an extended multi-fuel combustion model to simulate municipal solid waste combustion behavior, considering the different characteristics and properties of various waste components. The application of a new algorithm allowed for synergy between particles, influencing the combustion process. Results showed that in the fuel bed zone, complete combustion occurred too early, leading to higher simulated temperatures, while the difference between simulated and measured temperatures in the fluid phase was around 6%.

Summary: Large shares of variable renewable electricity (VRE) generation increase the demand for flexible power balancing capacities. Thermal energy storage (TES) can be used to increase heat-load flexibility and improve power balancing capacity in district heating (DH) production systems. A study on Swedish DH systems shows that they could reduce power deficits and surpluses by approximately 9% respectively, and heat pumps can contribute to reduced fuel use in DH production.

Summary: In this research, a municipal solid waste incineration plant with a capacity of 4 MW power generation was simulated and investigated using data from Tehran Municipality. The effective parameters were analyzed and optimization was carried out to achieve a power output of 19 MW. Exergy analysis was used to determine the losses in different parts of the plant. Economic and environmental analysis of the process was also conducted. The results showed that the plant can produce 298 tons of steam and generate 4 MW of electricity per day, with the incineration of 180 tons of waste and the use of 1,200 tons of air for combustion. The simulation was optimized to generate 19 MW of electricity, requiring an increase in waste discharge to 879 tons per day.

Summary: In this paper, a case study of an Italian treatment plant is conducted to optimize control schemes for acid flue gas produced by municipal solid waste fed to waste-to-energy plants. A two-stage dry sorbent system is used, with calcium hydroxide injected to reduce the hydrogen chloride content. By implementing a model predictive control structure, four different MPC solutions are tested and found to improve process performance compared to the current sub-optimal control architecture.

Summary: With the increasing number of data centers worldwide, there is a concern about their electricity demand on power grids and the environmental impact. Utilizing waste heat and integrating multi-energy hubs can mitigate these concerns at the urban scale. Through the use of CCHP-PV systems and district energy network connections, data centers can interact with residential customers, reducing grid electricity demand, energy consumption, and emissions. Experimental results showed significant reductions in power loss in the distribution grid, peak hour electricity demand, and greenhouse gas emissions associated with the data center's grid electricity consumption.

Summary: This study presents Stereoscopic particle image velocimetry measurements of a precessing motion resulting from a sudden expansion of an axisymmetric jet into a coaxial chamber. The flow field exhibits axisymmetric behavior, but contains unsteady coherent structures that create a precession around the central axis of the geometry. The presence of these structures in confined, non-swirling sudden expansion flows is a new finding.

Summary: Street bin litter (SBL) is a neglected waste stream that lacks in-depth research on its composition. Through five sorting experiments on SBL collected in Leuven, Belgium, it was found that the major fractions of SBL include illegally dumped waste (33 +/- 3%), organics (17 +/- 4%), and paper and cardboard (16 +/- 2%). On a functional level, approximately 35% of SBL consists of packaging, with beverage and food packaging constituting significant portions. Although economically viable material recovery may not be feasible, SBL cannot be ignored due to its visibility. Implementation of preventive measures and Extended Producer Responsibility schemes can effectively reduce SBL.
