Carbon Footprint Analysis and Reductive Project Evaluation of Iron-making Enterprise Based on LCA

摘要

There is a great significance to analyze carbon footprint of iron-making process and to reduce its environmental impact since iron-making enterprises generate massive greenhouse gas. In this paper, the environmental impact type referred to Global Warming Potential was applied to analyze the carbon footprint and environmental impact for each production process in iron-making enterprise based on life cycle assessment. Blast furnace process has the largest contribution in carbon footprint, followed by sintering process. According to the analysis, seven carbon emission reduction projects were carried out in series. Afterwards, the LCA was used to evaluate the environmental benefits by seven projects.
