The report about the Material Flows on the Big Island of Hawai’Ii I blogged about a while ago has another Sankey diagram which is interesting and I thought I share this one too.
The diagram shows the input/output flows of material in the Mauna Loa macadamia nut processing plant. Annual production is 3.4 tons.
“From a materials standpoint the plant exhibits an impressive import/export ratio, relying on imports to the island for only a small portion of its total production requirements.”
All flows are in Gg (that’s 10E9 grams, or 1000 tons). Apparently a tiny problem with the recycled biomass loop flows, but otherwise a nice one. Small and trace flows not to scale for good.
