By quantitatively analyzing the environmental impact of tinplate milk powder cans during the "cradle to gate" life cycle, the work aims to identify the key environmental impact categories and the most relevant life cycle stages in the production process of milk powder cans, and propose environmental improvement suggestions. Based on the European Union Product Environmental Footprint (PEF) method, SimaPro, the life cycle assessment software, and Ecoinvent database were used to model the milk powder cans during the life cycle. The Environmental Footprint (EF) 3.1 method was used to evaluate 16 environmental footprint indicators, and sensitivity analysis was conducted on the key parameters and multiple databases. Climate change, mineral and metal resource consumption, fossil resource utilization, particulate matter formation, human toxicity-cancer, and acidification were the most relevant environmental impact categories, resulting in the main environmental impact during the production process of milk powder cans. The carbon footprint for producing one milk powder can was 0.34 kg CO2 eq., mainly attributed to the energy and resource consumption during the production stage of tinplate raw materials, with a contribution rate of 61.76%. The transition of energy structure from traditional thermal power to clean energy could give the saving of greenhouse gas emissions from 2.94% to 11.84%. Improving the efficiency of raw material utilization, reducing waste generation, lowering electricity consumption, and accelerating the replacement of clean energy are effective ways to reduce the environmental footprint of milk powder cans throughout their life cycles.
