  1. Disposal of waste containing mercury Sven HagemannGRS

  2. Whate are Mercury Containing Wastes? End of life products Stabilized mercury Other mercury compounds

  3. Management Options for Mercury Containing Wastes Extraction Use ? Specially engineered landfill End of life products Stabilization ? Temporary storage Temporary storage Temporary storage Stabilized mercury Permanent storage in underground mines Other mercury compounds

  4. Other, not recommendeddisposaloptions  Source of mercury emissions during disposal and after closure Specially engineered landfill Municipal waste landfill End of life products Direct disposal without treatment Stabilized mercury Direct disposal hydrogen gas generation (corrosion) Permanent storage in underground mines Batteries

  5. Important steps in managing Mercury containing wastes • Separate Collection • Waste Collection Stations or Drop-off Depots • Collection at Public Places or Shops • Collection at Households by Collectors • Storage pending recycling/ extraction operations

  6. Important steps in managing Mercury containing wastes • Recycling/ extraction operations • Pre-treatment • Thermal treatment • Management of extracted mercury • Storage • Stabilization • Final disposal (operations not leading to re-use)

  9. Recycling anddisposal – somegeneralobservations • Separate collection • Withfew global exceptions, collectionquotaformercuryaddedproductsarelowornegligable Larger part:  municipalwaste  solid wastelandfill/ wasteincineration • Recycling ofmercuryproducts • Performedbyspecializedcompanies, oftenoperatinginternationally • As farasknown, in most Asian countries noor not sufficientrecyclingplants mercurywastecannotberecycledand not environmentallysounddisposed

  10. Disposalofmercurycontainingwaste– OpportunitiesandChallenges Opportunities • Well established technologies exist • Recycling generates Hg-free material that may be used again • Small amount of remaining waste that has to be disposed Challenges • Final disposal without treatment not recommended • Separate management requires effective separate collection • Recycling plants in Asia often lacking
