An ever-increasing demand for electrical power and soaring levels of energy consumption around the world have led to an energy crisis. Thus, this paper aims to review the conventional technologies against those of newer developments in electrical power generation such as using nitrogen generators. The nitrogen generator method is most appealing as it is a seemingly free energy already existing in nature. A nitrogen generator with a 5000 (Nm³/h) capacity has the potential to be used to analyze gas composition and the results are compared with the gas composition of a conventional steam turbine, which is used to pressurize 6000 (kWh) injection steam turbines. The magnetic bearing must be installed in both systems to modify all centrifuged systems which reduces all energy consumption in all systems by more than 50%. Artificial intelligence is used with the machine to analyze and control nitrogen gas flow to provide a more precise evaluation resulting in a more efficient technology. It should further be noted that the nitrogen turbine is superior to the steam turbine because it does not require the burning of fossil fuel to generate power. Hence, it is crucial to modify conventional technologies to improve energy sustainability and begin the long task of tackling environmental issues.

The alarming rate at which infectious waste is growing was an unsolved problem worldwide before the pandemic, and it has only gotten worse. It is especially prominent in the medical services, owing to the improper use or the lack of high-efficiency waste management systems. To address this issue, this paper presents a modification to the conventional rotary kiln incineration method using add-on ozone (O₃) at a concentration of 100–160 g/h in order to enhance its efficiency when treating emitted air pollutants. These pollutants of Hg, HF, TSP, SO₂, NO₂, CO, and HCl were measured, and their percent opacity concentrations were 0.006 mg/m³, 0.680 mg/m³, 21.900 mg/m³, 5.600 mg/m³, 16.300 mg/m³, 13.700 mg/m³, 0.022 mg/m³, and 6%, respectively. The amounts of these air pollutants were considerably lower than those released from a rotary kiln incinerator without the add-on ozone. Additionally, all the measurements were lower than the emission thresholds established in the US Environmental Protection Agency Emission Standards Reference Guide. Therefore, using the proposed rotary kiln incineration method modified with add-on ozone is suitable for use in the elimination of infectious waste in that it drastically reduces air pollution and improves air quality, resulting in environmental improvements aimed at mitigating the devastating impacts pollution has on human health.
