基于LCA的螺纹钢生产碳足迹测算及减碳研究

Measurement and Calculation of Carbon Footprint and Carbon Reduction Research for Production of Screw-thread Steel Based on LCA(Life Cycle Assessment)

螺纹钢是基础建筑构件的重要钢材,被广泛应用于房屋、桥梁、道路等工程建设,因其用量大,螺纹钢在建材中的碳排放占比也较高,其制造流程的碳足迹管理和评价研究显得尤为重要。文章通过分析螺纹钢生产过程碳素流的运行和转换,找出螺纹钢减碳的重点方向。采用LCA方法,对产品的碳排放和碳足迹数据进行量化,对所有潜在影响因素进行计算,从而识别控制碳排放重点区域,为包钢制定减碳措施和规划提供指导,并成功实现了螺纹钢产品在EPD平台上发布环境产品声明。

As the important steel of basic building components,screw-thread steel is widely used in such engineering constructions as buildings,bridges and roads.Its proportion of carbon emission is higher in building materials due to its large consumption so that the management and evaluation research of carbon footprint in its manufacturing process are particularly important.In this article,the key direction for its carbon reduction is found out through analyzing operation and conversion of carbon flow in its production process.The data of carbon emission and carbon footprint of products is quantified as well as all of potential influencing factors are calculated with the LCA method so as to identify and control key areas of carbon emission,which could provide guidance for Baotou Steel to establish measures and plans of carbon reduction as well as environmental product declarations(EPD)of screw-thread steel products are successfully released on the EPD platform.
