From this presentation by Berlin-based consulting firm UEC comes the below Sankey diagrams on sorting of waste in a waste treatment facility in 2003.
No absolute values are given, only a percentage breakdown of the waste that is being treated.
After the first steps, the drum sieve (‘Siebtrommel’) splits the waste flow in three main fractions based on the size of the shreddered waste. The blue arrow are unsorted remains, the colored ones are recovered materials.
Only apparent flaw of this Sankey diagram is that the arrow labels show ranges for values. An accompanying table in the presentation has the minimum and maximum sorting quotas. Not clear which value was used for determining the arrow widths.
