3 6 4 Evaluation of consequences and hotspots

Recommendation ITU-T L.1031 points out that assessing the consequences of inappropriate
WEEE management at any point in the value chain provides insights into socio-economic and
environmental impacts, known as “hotspots”. For this purpose, the flow diagram presented in
3.6.2.1 Current material flows is used as a basis, and the results of the mass flows and balances
are analysed in terms of potential socio-economic and environmental impacts, as well as
shortcomings of the management system that do not allow the generation of information for
the material flows. Figure 59 shows the hotspots identified.
