| Use advice for data set | When using this data set for Life Cycle Assessment (LCA), the user should consider the energy (electricity) consumption specific to the feed processing stage. The functional unit for the study is defined as '1kg of eggs'. Users should ensure that this functional unit is consistent with the scope of their assessment. Additionally, users should take into account the pollutant emission factors as provided in the data, which originate from Hu Zhiyuan's research, to accurately reflect the environmental impact during the stated life cycle stage. |
| Technical purpose of product or process | This data set pertains to the life cycle of egg production at an intensive poultry farm in Heilongjiang Province, China. It includes the energy consumption, specifically electricity use, during the feed processing stage. The main output product of this process is eggs, and thus, the material represented by this data set is used for the production of eggs. |

| Technology description including background system | Quantitative method was used in this study. This evaluation includes a re-examination or revision of the objectives and scope of the research to determine how the objectives of the research can be met. According to the actual situation of layer production, the technical framework of life cycle impact assessment (FIG. Impact assessment includes four steps: classification, characterization, standardization and weighted assessment. (1) Classification: The input and output data in the life cycle inventory analysis were classified into different types of environmental impact. Based on the analysis results of the life cycle inventory of laying hens, the following four types of environmental impact were evaluated: global warming, environmental acidification, eutrophication and photochemical ozone synthesis. (2) Characterization: Quantitative inventory analysis of data to determine the degree of impact of four types of environmental impact. This makes the amount of environmental pollution that would otherwise not be comparable comparable. (3) Standardization: First of all, standardization benchmarks should be established to provide comparable standards for the relative sizes of the four environmental impact types of global warming, environmental acidification, eutrophication, and photochemical ozone synthesis. (4) Weighted assessment: is the process of grouping environmental impact into a unified indicator - environmental load size, so as to directly compare different production systems. |
