Emissions and environmental compliance are growing concerns in the use of aluminium melting furnaces. Combustion-based furnaces release CO₂ and other pollutants such as nitrogen oxides (NOₓ) and particulate matter. Governments and regulatory bodies have set stringent limits on emissions, pushing manufacturers to adopt cleaner technologies. Filters, afterburners, and scrubbing systems are commonly employed to reduce harmful outputs. Additionally, electric melting systems, powered by renewable energy sources, are gaining traction as an eco-friendly alternative.
