Management Options for Mercury Containing Wastes

Extraction

Use

?

Specially engineered landfill

End of life products

?

Temporary storage

Temporary storage

Temporary storage

Stabilized mercury

Permanent storage in underground mines

Other mercury compounds


Other not recommended disposal options

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


Important steps in managing mercury containing wastes

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


Important steps in managing mercury containing wastes1

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)

Recycling and disposal some general observations

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


Disposal of mercury containing waste opportunities and challenges

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
