Hazardous and Toxic Waste, Aluminum Slag, Sulfuric AcidAbstract
Hazardous and toxic waste (B3), including aluminum slag, requires proper management to minimize risks to human health and the environment. This study evaluated the initial performance of a prototype for treating aluminum slag waste using temperature and gas levels as monitoring parameters. A total of 10 kg of aluminum slag was divided into two 5 kg samples: untreated slag and slag mixed with 10% H₂SO₄ at a 1:1 ratio. Testing was conducted in three 5-minute sessions with the blower turned off. Sample 1 showed temperatures of 30.1–30.8°C and gas levels of 26–28, while Sample 2 increased from 44.8°C to 72.12°C and from 72 to 500 in gas level. The MQ-2 reading exceeded the programmed threshold of 400 in the second and third sessions. Cooling was subsequently performed using a blower. Cooling data were estimates, requiring further validation through actual measurements and sensor calibration.
