Systems analysis of stock buffering: development of a dynamic substance flow-stock model for the identification and estimation of future resource, waste streams and emissions

The dynamic behaviour of the product stock, which is mainly determined by the behaviour of the stock’s inflow (purchases of new products) and stock’s outflow (discarding of

Now it is phased out completely, at least in the Netherlands (Tukker et al. 2001), although still present in old stocks. Furthermore, lead is applied in a number of small products

The non- intentional inflow of lead into the Dutch economy is estimated as the amount of lead in the coal and oil used in electricity production, in zinc and iron ores processed in

The inflow of lead into the stock of road construction materials (asphalt) originates from three sources: fly ash generated from the incineration of lead non-intentional

The model also shows that the main platinum losses are due to the waste management of fuel cell and catalytic converters and the production of platinum from primary sources

The model developed and presented in this thesis is a dynamic substance flow-stock model that can be used to estimate future resource availability, emissions and waste streams..

The variability of the residuals appears to be the same across all values of the explanatory variables (GDP/C, population and time) and the predicted dependent variable (inflow

The model focuses mainly on the economic subsystem and includes the extraction and production of Pt (from both primary and secondary resources), and the production, consumption
