RIVM Report 481504003
The National Institute of Public Health and the Environment (RIVM) in co-operation with the Netherlands Bureau for Economic Policy Analysis (CPB) converts economic into physical scenarios to estimate the pressure of economic activities on the environment. A model called STREAM (Substance Throughput Relating to Economic Activity Model) is under development to link economic to physical variables. Our research focused on modelling iron and steel recycling in the primary steel production sector. For Western Europe the main explanatory variable is the product mixture. A relationship exists between the product mixture (categorised as long products (e.g. tubing) and flat products (e.g. plate and sheet)) and the scrap consumption in the primary steel production process. In the Netherlands, where the scrap consumption of the primary production process is modelled by means of a trend analysis, a significant relationship between iron and steel scrap consumption and the mixture of products was not found to exist.
