A New Algorithm for Life Cycle Inventory Analysis of Reproducible Materials

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.

Key words:life cycle assessment; reproducible material; inventory analysis; recovery capacity; recovery level
