LCA Phase 1 results

A Life Cycle Analyses was performed in cooperation with de company CE Delft on the various treatment routes on zinc and copper recovery from WtE bottom ashes. The following goals were investigated:

  1. Compare the DEMO phase 1 process (indicated as Now) for treatment of non-ferrous concentrates (copper/zinc) from WTE (waste-to-energy) bottom-ash with with the conventional way of treating non-ferrous from bottom ash.
  2. Compare the recovery of zinc from non-ferrous flows from WTE bottom-ash with the conventional production of zinc from primary zinc ores.

 

The picture below shows a summary of the results.
