Use advice for data set | When utilizing the life cycle assessment data of the milk production process, consider the scope strictly confined to production and packaging within the enterprise. The environmental impacts of material transportation within the production site are deemed insignificant. Exclusions include processes outside the facility that contribute to the environmental load. For accurate LCA results, comply with the relevant ISO standards for consumption analysis and environmental emissions associated with each stage of milk production. Use the identified environmental impact factors for the improvement of clean production practices and enhancement of the environmental performance in the milk industry. |
Technical purpose of product or process | The technical use described here is the production and packaging of ordinary bagged milk intended for consumption, which is part of the life cycle assessment of milk produced and marketed in the Changchun area. The milk is used as a consumable in the food industry and is particularly formatted for everyday retail and consumption. |

Deviations from LCI method approaches / explanations | In this paper, according to the relevant ISO standards, LCA method was used to analyze the consumption and environmental emissions at each stage of milk production, establish the basic database of milk production life cycle, identify the relative size of the environmental impact of each stage of milk, and find out the main factors of environmental impact. Therefore, it provides opportunities and ways for milk enterprises to implement clean production and improve the environmental performance of milk production. | ||||
