Process Data set: Milk production ; packaging (en) en zh

Key Data Set Information
Location CC-JL-CN
Geographical representativeness description The research object of this paper is the ordinary bagged milk sold in a city in Changchun area
Reference year 2006
Name
Milk production ; packaging
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.
Classification
Class name : Hierarchy level
  • ILCD: Unit processes / Materials production / Food and renewable raw materials
General comment on data set According to the research scope of this paper, the milk production life cycle is divided into the following two subsystems: production and packaging. Due to the relatively concentrated production workshop inside the enterprise, the environmental impact caused by material transportation is negligible.

Type of data set Unit process, single operation
Deviation from LCI method principle / explanations None
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.
