    Nature of the EOL ODS issue

    EOL ODS mgt. steps and technologiesCaptureDestructionValidation

    Barriers to EOL ODS management

    Options to address barriers

    Approach for the Caribbean Region

  • ODS Bank and EOL ODSThe ODS Bank is what is in productive use that has potential for atmospheric release (consumption not yet emitted).

    EOL ODS is no longer in productive use and without the prospect thereof (ODS that is now subject to atmospheric release).

    By definition EOL ODS excludes ODS that is recovered/reclaimed for future productive use.

    EOL ODS is a waste whose default management option results in global environmental damage.

    Essentially a hazardous waste requiring environmentally sound management (ESM) but generally without a local environmental/health risk.

  • ODS Bank/EOL ODS: Global ContextESM of the global ODS Bank and EOL ODS is one of the remaining ozone layer threats to be addressed by the MP.

    Capture and environmentally sound destruction of the global ODS Bank could theoretically have significant accelerating effect on ozone layer recovery.

    Parallel climate change impacts

    In practice the actual potential benefits of EOL ODS mgt. is much less due to practical limits on timing, ability and cost effectiveness of capture/destruction (CTC an exception)

    Unlike actual ODS phase out, management of ODS banks and EOL ODS is not subject to direct control measures under the MP.

  • Sources/Types of EOL ODSRefrigerantsCFC-12, HCFC-22, HCFC blendsDomestic/commercial appliances, large refrigeration & A/C equipment

    Retained in FoamsCFC-11, HCFC-141b, HCFC-22, HCFC-142bDomestic/commercial appliances, building materials, packaging

    Fire protection systemsHalon 1211, 1301,2402Decommissioned systems

    Redundant/obsolete stocks, confiscations MB

    Excess production/ by-products - CTC

    EOL ODS Destruction

    Menu of technologies available combustion and non-combustion (all have a thermal element), future potential for chemical dechlorination

    Practical OptionsHigh temperature incinerationCo-disposal in industrial combustion facilitiesPyrolysis/plasma arc

    Environmental performance requirementsDestruction efficiency/destruction removal efficiency (>99.99%)Unintended release emissions (PCDD/PCDF < 0.1 ng TEQ/Nm3) )

    Documentation/due diligence safeguards to provide assurance of destruction and environmental performance

  • UNDP Demonstration Destruction ProjectsOriginal Concept - Demonstration of a range of destruction options

    Cuba: Capture capacity pre-establishedCement kiln

    ColumbiaIncremental capture capability (consolidation/storage)Export or regional specialty facilities

  • UNDP Demonstration Destruction Projects (2)

    Ghana:Incremental capture capability (consolidation/storage)Test small local destruction versus export

    Brazil:Link to emerging appliance de-manufacturing programUtilization of existing HW Mgt infrastructure or/and or integrated de-manufacturing processing and destruction

    Overall Conclusion: Using existing HW infrastructure has significant cost advantage

  • Barriers to EOL ODS ManagementTechnology/infrastructure/operational barriers relatively minor

    Major practical barriers are:Creditable institutional arrangements for ownership care and custodyRegulatory controls to stimulate capture of sufficient quantities to have any impactEmission bansEOL ODS a regulated hazardous wasteEnforcement and meaningful penaltiesFinancing a high cost of the EOL mgt. process

  • Financial Mechanisms to Support EOL ODS Mgt.Public assumption of financial liability

    Environmental stewardship charges

    Voluntary producer responsibility

    Energy efficiency incentives for retirement

    Carbon finance

    Convention based financing (MLF)

  • Potential Action in the Caribbean RegionCharacterized by:Low volume potentialWidely distributedAbsence of policy/regulatory/economic driversBasic capture capacity available

    Action should focus on capture for future destruction

    Development of collective/regional capacity

    Coordination of policy and regulatory action

    Collective care and custody mechanism

    Destruction in the region unlikely

    Destruction likely financed by carbon finance/grants

  • ConclusionsGlobally the amount of EOL ODS actually destroyed will be modest

    Priority targets are CFC-12 and halons with CFC-12 having a narrow window over the next 5-10 years

    High consuming countries (developed/developing) is where the impact can be maximized

    EOL ODS needs to be regulated and managed as a hazardous waste

    Initial focus should be on capture

  • Conclusions (2)EOL ODS destruction not limited by technology

    Limitations are institutional/regulatory/financial

    LVCs need to act collectively

    Final destruction integrated with ESM HW management generally and carbon finance as this matures.
