本文对英国的钢铁使用情况进行了分析，并探讨了在使用后废弃的钢铁中有多少是回收利用的。本论文系列的第一部分调查了英国钢铁的生产和消费趋势，而本文的重点是废料的产生和回收。关于进入不同类别货物的钢铁数量的资料，以及它们的估计寿命值，使人们能够模拟每年从使用阶段以寿命结束废料的形式释放的钢铁。这是化学反应工程中常用的停留时间分布理论在物料流计算中的应用。通过比较模拟产生的废料与实际废料消费在英国，我们获得估计损失或积累的钢铁废料在英国。该模型表明，2001年可能作为报废废料使用的废料中，有多达30%要么在经济系统内积累，要么被丢弃到垃圾填埋场。(C) 2006 Elsevier B.V.版权所有
This paper presents an analysis of the use of iron and steel in the UK and explores how much of the iron and steel is recycled when it becomes obsolete after use. The first part of this paper series investigated production and consumption trends of iron and steel in the UK, whereas this paper focuses on scrap generation and recycling. Information on the amounts of iron and steel going into different groups of goods, together with values for their estimated lifetimes, have enabled modelling of the annual release of iron and steel from the use phase in the form of end-of-life scrap. This is an application to material flow accounting of the theory of residence time distributions used routinely in chemical reaction engineering. By comparing modelled generation of scrap with actual scrap consumption in the UK, we obtain estimates of loss or accumulation of iron and steel scrap in the UK. The model indicates that as much as 30% of the scrap that was potentially available in 2001 as end-of-life scrap has either been accumulated within the economic system or lost to landfill.
