Reducing CO2 Emissions Using an Eco-Friendly System to Faltering Air Made from Recycled Material: Activated Carbon that activated with H3PO4

Air pollution is among the major issues in Egypt due to fast urbanization, industrial activities, and poor waste management practices. This research paper will develop an air filtration system using activated carbon from waste materials such as coal ash to reduce CO ₂ and other pollutants in the air. It shall be constructed to purify, with a minimum rate of 20%, a preconditioned air sample between 600–1500 mL within less than 10 minutes. This includes an air compressor, active carbon filter, fan, and sensors checking the level of CO ₂ (MQ135). The filtration process shall involve air intake, passing through filters, and blowing it out by the use of a fan. This measures the efficiency of the system by measuring CO ₂ pre- and post-filtration with displays made on an LCD. Therefore, the contribution goes beyond air pollution but also includes adding to waste management by the reutilization of waste material; it's a way to enhance the environment for the sustainability of better public health.
