Cement production significantly impacts air quality by emitting particulate matter (PM), nitrogen oxides (NOₓ), sulfur dioxide (SO₂), and heavy metals. Dust from quarrying and grinding contributes to PM emissions, while fuel combustion in kilns releases NOₓ and SO₂, leading to environmental and health concerns. Additionally, the high-temperature processes can emit heavy metals into the atmosphere.
High consumption of raw materials like limestone, clay, and sand leads to habitat disruption and biodiversity loss.
Cement production is energy-intensive, primarily relying on non-renewable fossil fuels, which contributes to resource depletion and significant CO₂ emissions. Additionally, substantial water is required for cooling and dust suppression during the manufacturing process, potentially straining local water resources.
Production generates waste materials and pollutants, including kiln dust and heavy metals, which can contaminate soil and water if not properly managed.
Quarrying activities can lead to deforestation, soil erosion, and landscape alteration, affecting local ecosystems.
