Medical Waste to Energy: Pyrolysis Oil of Saline Containers Waste Fuelled CI Engine Characteristics Evaluation With Hybrid Nano-Fuel

The growing medical industry plays a crucial role in maintaining human health. However, it also generates a significant amount of medical waste, including plastic saline containers. Properly managing this waste is essential to minimize environmental pollution and reduce the burden on waste management systems. Converting saline container waste into fuel through the pyrolysis process presents a valuable solution for energy demand. Transforming this saline container waste into a useful resource addresses the issue of plastic waste pollution. This research aims to support the Sustainable Development Goals of 3, 7, 11, 12, and 13. The produced Pyrolysis oil of Saline container Wastes (POSCW) was used to prepare three different blends (25, 50, and 75 vol% concentration with diesel) of biodiesel, two different nano-fuels, and one hybrid nano-fuel. The POSCW100, POSCW75D25, POSCW50D50, POSCW25D75, POSCW25D75 + CONP, POSCW25D75 + MWCNT, and POSCW25D75 + CONP/MWCNT were prepared, characterized for fuel properties, and tested in a 5.2 kW CI engine test rig at constant speed and various load conditions along with standard fuel of Pure diesel (PD100). The results reveal that POSCW100 recorded near-diesel performances. Nano-fuels and hybrid nano-fuels recorded appreciable results, particularly the POSCW25D75 + CONP/MWCNT hybrid nano-fuel, which outperformed in terms of in-cylinder pressure, heat release rate, engine performance, and emission performance.
