This study proposes a very compact incinerator that also produces heat (VICH). The goal of this work is to design, model, test, and assess a novel VICH system using computational fluid dynamics (CFD), energy, economic, environmental, and exergy (4E-CFD) methodologies. The findings of the CFD analysis utilising three hot fluids—hot water, steam, and hot oil—suggested that hot water was the optimal working fluid for integration with an organic Rankine cycle at a temperature of 116.57 °C (ORC). Furthermore, the testing findings indicated that a refusederived fuel (RDF) with a low heating value of 16.62 MJ/kg could raise the hot water temperature to 111.18 °C, which was consistent with the CFD modelling result. The efficiency for energy and exergy were roughly 23.35 percent and 20.93 percent, respectively. A life cycle assessment (LCA) using a functional unit of 1 kgRDF-1 and a lifespan of 20 years found a climate change of 3.30E-03 kg CO2 eq, ozone depletion of 1.52E-10 kg CFC-11 eq, particulate matter formation of 8.36E-06 kg PM10 eq, terrestrial acidification of 1.30E-05 kg SO2 eq, freshwater eutrophication of 1.83E-06 kg P Construction accounted for 36.07 percent of the LCA impacts, followed by operations at 63.41 percent, landfill decommissioning at 0.52 percent, and recycling at 3.99 percent. The levelized cost of the waste disposal combined heating procedure was roughly 0.006 USD/kgRDF in the economic figures.
