Introduction In this series of two papers, we use time-dependent material flow analysis (MFA) to examine the UK iron and steel cycle between 1970 and 2000. According to Bringezu and Moriguchi (2002), MFA can be defined as the quantitative accounting of material inputs and outputs of processes in a systems or chain perspective.
