Supply, excess supply and surplus mercury 3

National/ regional mercury supply What is Surplus Mercury? 4 Need to manage surplus mercury  storage  disposal National / regional demand for products & proceses National/ regional surplus Elemental Hg & Hg compounds like calomel

Important Sources of Supply and Commodity/ Waste 5 Export Non –ferrous metal production (zinc, gold) Decommissioning of mercury cells (chlor alkali) Recovery from mercury waste (products, catalysts) Primary mercury mining Mercury compounds like calomel (mercurous chloride) Elemental mercury Commodity mercury and mercury products intended for later use or sale (OR not required for disposal) Mercury waste: Intended or required for disposal by national law (covered by Basel Convention)

Important Sources of Mercury Supply in Asia – Status Quo 6 Export Non –ferrous metal production (zinc, gold) Decommissioning of mercury cells (chlor alkali) Recovery from mercury waste (products, catalysts) Primary mercury mining Zinc smelters (Japan, China?) India, Pakistan, other? Recycling of catalysts from VCM production (China) Recycling of waste from SE Asian oil+gas industry (exported to EU/ USA) Recycling of waste products: Japan Kyrgysztan China

Prediction of future mercury demand 17 Reduction of Hg use for VCM production: t/a until 2030 (-100%) Reduction of Hg in products (not lamps): -300 t/a until 2030 (-37%) Use of Hg in ASM: -250 t/a until 2030 (-67%)

18 Supply and Demand Scenario “reduced mining” Reduced Hg mining due to reduced domestic demand “Base” supply: by-product Hg + recycling Reduced demand for ASM, VCM, products ASM, Products Surplus Hg

19 How Much Surplus Mercury Will Have to be Managed in South/ South East and East Asia? (Concorde 2009) Main assumptions: VCM production: decrease of consumption after 2015 Zinc smelting: strong increase of Hg recovery between now an 2030 Alternative scenario: 7,500 t (reduced supply for ASM) Regional surplus 5,500 t ( ) Possibly national surpluses ? ?  Management options for surplus mercury?  AIT/RRCAP study (2010)

Illustration of Estimated Volume of Surplus mercury 20 Annual regional Hg surplus of 200 t (as elemental Hg) ~ 15 m 3 ≈ space in small delivery truck Annual global surplus of t (as elemental Hg) ~ m 3 ≈ space in 40 feet container  Practical storage space always higher (depending on storage concept)

Data source: UN COMTRADE database21 National Hg surplus National surplus when VCM Hg free & Hg recovery in smelters National legal surplus from products & smelters, oil/gas National excess demand for ASM ~Equilibrium or surplus from smelters

National net surplus and legal surplus 22 Net surplus: National supply > National demand (e.g. Japan) Legal surplus:(Potential) sources of Supply that are subject to national storage/ disposal obligation, e.g. Hg in end of life products, Hg from decommissioned chlor- alkali plants (e.g. Cambodia, Philippines) Storable surplus: amount of surplus mercury that remains in the country and has to be stored/ disposed (e.g. after export of mercury containing waste, e.g. oil/ gas waste from Indonesia)

Estimated Surplus Mercury by Region for 40 years 23 Surplus mercury [t]

Illustration of Estimated Volume of Surplus mercury 24 Annual regional Hg surplus of 200 t (as elemental Hg) ~ 15 m 3 ≈ space in small delivery truck Annual global surplus of t (as elemental Hg) ~ m 3 ≈ space in 40 feet container  Practical storage space always higher (depending on storage concept)

Inventory of mercury waste 25 No inventory so far  estimates Products Demand: 837 t -Part exported -Part: release to air -Part re-imported as waste -Part exportes as waste -3% recycling Processes Demand: > 1400 t -VCM: 1000 t, 15% waste? -Chlor-alkali t waste - ASM: 380 t: 2/3 sediments/tailings By-product Hg in Zink > 500t: only air? Hg in Gold  Tailings? Natural gas  partly exported

26 Conclusions Regional mercury surplus probably only after 2020 National net surpluses may occur sooner National legal surpluses already exist in many countries
