Abstract
Substance flow analysis (SFA) provides a helpful tool for the study of the industrial metabolism of a certain substance within a regional level. This paper presents SFA of steel in four countries, namely Australia, Brazil, China and India. These countries are traditionally economically mineral dependent and are major contributors in global iron ore production. For example, in 2010 together these countries produced 81% of world iron ore. Based on the analysis it was found that Australian and Brazilian iron ore stocks will deplete rapidly while China and India are accumulating. This paper then presents a discussion on sustainability issues related to substance flows of steel stocks. The study is aimed at providing better understanding of stocks and flows and to inform the policy making for achieving the industrial metabolism and consequently leading to better management of resources and recycling of steel in the countries under study.
