Summary: A multiphase CFD-DEM model was developed to simulate a waste-to-energy gasifying and direct melting furnace. The model used characterizations from laboratory experiments to dynamically simulate the density, heat capacity, and fate of waste and charcoal particles under different conditions. The simulation results matched well with site observations, providing insights into the functioning zones and dynamic changes within the furnace. The study demonstrates the utility of the model for optimizing operating conditions and scaled-up design for future waste-to-energy facilities.

Summary: The study showed that increasing air preheating temperature led to higher rates of moisture evaporation and volatile release, potentially raising the local maximum temperature in the furnace. By using different primary air temperature setups, it was possible to maintain high rates of moisture evaporation and total mass loss, while reducing the rate of volatile release. The multi-temperature primary air setup effectively controlled the local maximum temperature in the furnace while encouraging moisture evaporation and minimizing volatile release.

Summary: Due to the large uncertainty in the MSWI process, a novel event-triggered control method based correntropy self-organizing TS fuzzy neural network (ET-CSTSFNN) is proposed. The method adaptively grows or prunes the neurons in the rule layer based on activation intensity and control error. The proposed ET-CSTSFNN controller achieves accurate furnace temperature control and reduces the number of controller updates significantly compared with other traditional control methods.

Summary: The study proposes an integrated system to convert medical waste into value-added products with almost zero emissions through tail gas treatment. Energy from medical waste is recovered using steam generators and supercritical CO2 cycles to produce high-temperature/pressure steam and electricity. A simple power generation cycle achieves a net electricity efficiency of 22.4% through optimization. The proposed system also includes a pressurized reactive distillation column to purify the resultant tail gas, converting nearly 100% of SO2 and 75% of NO2 into their acid forms.

Summary: This study conducted advanced computational fluid dynamics simulations to optimize a moving-grate boiler for municipal solid waste, in order to accommodate changes in waste properties. The results showed that after adjusting the air supply and thermal input, the boiler operation improved and was better able to adapt to the new waste.

Summary: The study confirms that the concept of incineration is fading due to social opposition and shifting towards a broader concept like valorisation. The goal for policymakers should be to create a circular economy without waste, by respecting the waste hierarchy and managing waste in the order of prevention, minimisation, reuse, valorisation, recovery, and elimination.

Summary: The use of incineration bottom ash (IBA) from fluidised bed (FB) combustion technology as a precursor for alkali-activated binders (AABs) was evaluated. IBA-FB was compared with IBA from moving grate (IBA-MG) combustion technology. The formulation of AABs using IBA-FB and IBA-MG was assessed from various perspectives, revealing differences in workability, consistency, porosity, and mechanical strength.

Summary: Plasma gasification is a promising technology for sustainable utilization of hazardous waste. In this study, numerical simulation and optimization design were performed using Ansys Fluent software, and it was found that the best internal combustion condition was achieved when the material was injected from the side tangential direction and the plasma flare had a horizontal angle of 23 degrees.

Summary: Plastics are crucial to the economy and daily life, but plastic pollution is a global issue. The European Strategy for Plastics in a Circular Economy, adopted in January 2018, aims to tackle this problem by promoting recyclability of plastic products by 2030. This study evaluates various plastic materials and technologies through a review of Life Cycle Assessment (LCA) analyses. The environmental impacts of different plastics in landfill disposal and incineration with energy recovery were analyzed and compared, highlighting the potential for energy recovery.

Summary: This study evaluates the use of municipal solid waste and sludge in a waste to power initiative. It utilizes a multiscale approach, including a techno-economic analysis to determine optimal operating conditions and estimate production and investment costs. The facility includes a boiler, flue gas treatment chain, turbine, and cooling tower. By processing waste from cities with a population above 250k, power can be produced at a competitive price of 0.06 euro/kWh. The investment cost for the facility exceeds 30 Meuro, with gas treatment accounting for 19%, turbine 37%, and boiler 31%.
