An interesting Sankey diagram of sugar production can be found on p. 23 and p. 24 of the 2002 report ‘Möglichkeiten der Wertschöpfungssteigerung durch Abfallvermeidung (biogener Reststoffe) und Nebenproduktnutzung – Feasibilitystudy’ by Austrian researchers Herbert G. Böchzelt, Niv Graf, Robert W. Habel, Johann Lomsek, Susanne Wagner, Hans Schnitzer (all of Joanneum Research).

Why interesting? Because the diagram wouldn’t fit on one page in the report the authors decided to cut it in two parts. Two streams of the first diagram are continued in detail in the second Sankey diagram shown on the next page.


All flows are in mass percent based on an input of 100% sugar beets (‘Rübenschnitzel’, with -schnitzel apparently meaning ‘chips’). The output of 16 mass-% ‘Presschnitzel’ (pressed beet pulp) and 4.18 mass-% ‘Melasse’ (molasses) is further detailed in the second diagram.

Mind that arrow width is different in the two diagrams, so that they two can not be compared directly. Because water dominates the first diagram, the smaller mass flows of the second diagram would be barely visible, if the two were at the same scale.

  1. Australian Metal Flows | Sankey Diagrams Says:

    […] The smaller yellow diagram section on the left actually just shows mining activities in Australia and the fact that the largest portion of mining output (ores) are exported. Only 7.5 Mt are processed within Australia. This Sankey arrow is then blown up and corresponds to the yellow input stream into the second diagram [a similar solution to decouple diagrams with different scales was presented in yesterday’s post].
