Outflows of metals from existing stocks to the solid waste compartment

The quantities of metals flowing out with solid waste from each of the stocks of the four metals are rather uncertain. It should also be noted that these quantities leaving the metal stocks in Stockholm include scrap going to recovery and recycling, and should therefore not in reality be labelled "waste". However, within the borders of the city of Stockholm there are relatively limited facilities for such metal recovery and recycling, and therefore, the "waste" is considered as a quantity leaving the system. From the waste compartment as such the losses of metals to the biosphere are very small, e.g. from incineration and with leachates from landfills.
