考虑回收能力的材料生命周期清单分析模型

A New Algorithm for Life Cycle Inventory Analysis of Reproducible Materials

摘要:

对可再生材料进行生命周期清单分析时,需要考虑材料回收率的影响.分析了以往几种可再生材料生命周期清单分析算法所存在的问题,将回收率分解为回收能力、回收水平2个因素,提出了同时考虑这2个因素的可再生材料生命周期清单分析新算法.以建筑中常用的钢板、钢筋、铝、玻璃及混凝土为例,比较计算了新算法与老算法之间的差异.结果表明,新算法能较大提高生命周期清单分析的计算精度.

Abstract:

Recovery rate should be taken into account when life cycle inventory of reproducible materials is analyzed.The existing problems of past algorithms are discussed.The recovery rate is separated into recovery capacity and recovery level,and a new algorithm contains these two factors for life cycle inventory analysis of reproducible materials is proposed.The difference between each algorithm is calculated with the steel plate,steel reinforcement,aluminum,glass and concrete for instance.It shows that new algorithm is more accurate than others.
