摘　　要：回收废铝易拉罐生产新铝制易拉罐材料可以有效减少碳排放,因此基于生命周期评价方法分析了铝制易拉罐罐体材料的碳足迹,并使用Cut-off和CFF循环分配方法解析再生产品的碳排放构成。研究发现,使用原铝生产的铝制易拉罐罐体材料碳排放显著高于回收铝罐的碳排放,且主要来自原铝生产过程。Cut-off方法计算的碳排放为原生产品20705kgCO_(2)eq/t、再生产品6040kgCO_(2)eq/t,而CFF方法计算的碳排放为原生产品10146kgCO_(2)eq/t、再生产品8093kgCO_(2)eq/t,表明CFF方法提供了更科学的循环分配依据,能更准确反映环境责任。Recycling waste aluminum cans to produce new materials can effectively reduce carbon emissions.Therefore,the carbon footprint of aluminum can body materials was analyzed based on life cycle assessment method,and the carbon emission composition of recycled products was analyzed by Cut-off and CFF cycle allocation methods.The results show that carbon emissions from aluminum cans made with primary aluminum are much higher than those made with recycled aluminum,primarily due to the primary aluminum production process.The Cut-off method calculates emissions of 20705 kgCO_(2)eq/t for primary aluminum and 6040 kgCO_(2)eq/t for recycled aluminum,while the CFF method calculates 10146 kgCO_(2)eq/t for primary aluminum and 8093 kgCO_(2)eq/t for recycled aluminum.The CFF method provides a more accurate reflection of environmental responsibility.
