Redução CO2 por kg Al reciclado

This calculator estimates the reduction of carbon dioxide (CO2) emissions by recycling aluminum instead of producing primary aluminum. For each kilogram of recycled aluminum, approximately 9 kg of CO2 emissions are avoided, considering the entire life cycle from bauxite mining to smelting. The calculation is simple: multiply the amount of recycled aluminum (in kg) by the factor of 9 kg CO2/kg Al. The result is the amount of CO2 avoided, expressed in kilograms.

When to use? Ideal for individuals and companies wishing to quantify the environmental impact of their recycling actions. For example, when recycling aluminum cans, industrial scrap, or other aluminum waste. Also useful for sustainability reports, carbon offset projects, and environmental education. The calculator provides a quick estimate based on data from scientific literature, such as from the IPCC and industry associations.

Important considerations: The factor of 9 kg CO2/kg Al is a global average. The actual value may vary depending on recycling efficiency, local energy mix, and type of aluminum waste (cans, sheets, etc.). For more precise calculations, consider regional factors. Additionally, aluminum recycling also avoids other environmental impacts, such as water pollution and energy use, but this calculator focuses solely on CO2.
