Presentation Scope

• ODS Banks/ “EOL” ODS in context of ozone layer protection and the MP

• Nature of the EOL ODS issue

• EOL ODS mgt. steps and technologies Capture Destruction Validation

• Barriers to EOL ODS management

• Options to address barriers

• Approach for the Caribbean Region

Page 3: Management of  ODS Banks/”End of Life” ODS

ODS Bank and EOL ODS

• The 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.

Page 4: Management of  ODS Banks/”End of Life” ODS

ODS Bank/EOL ODS: Global Context

• ESM 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 ODS

• Refrigerants CFC-12, HCFC-22, HCFC blends Domestic/commercial appliances, large refrigeration & A/C

equipment

• Retained in Foams CFC-11, HCFC-141b, HCFC-22, HCFC-142b Domestic/commercial appliances, building materials,

packaging

• Fire protection systems Halon 1211, 1301,2402 Decommissioned systems

• Redundant/obsolete stocks, confiscations – MB

• Excess production/ by-products - CTC

Page 6: Management of  ODS Banks/”End of Life” ODS

Factors in Prioritizing EOL ODS Management

• Volume - CFCs (near term), HCFCs • ODP – CFCs, halons• GWP – CFC-12, HCFCs• Availability in quantity

GDP Population Originating sources

• Sector Accessibility Commercial/domestic refrigerants Halons

• Cost of capture/processing/destruction Form available Existing capture infrastructure/institutions Access to destruction capacity

EOL ODS Management ProcessCapture Destruction Validation

EOL ODS Capture -Refrigerant/Halons Removal from equipment Decision on future productive use (is it a

waste?) Consolidation/secure storage Ownership/care and custody arrangements Documentation/analysis Base on existing service infrastructure

upgraded for secure storage arrangements

Page 8: Management of  ODS Banks/”End of Life” ODS

EOL ODS Management ProcessCapture Destruction Validation

EOL ODS Capture -Foam Removal from equipment/application Process option 1:

Size reduce Package for destruction Consolidation/secure temporary storage

Process Option 2 Blowing agent extraction Potential integration with destruction

Ownership/care and custody arrangements Tracking/Documentation of origin/analysis

EOL ODS Management ProcessCapture Destruction Validation

EOL ODS Destruction

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

•Practical Options High temperature incineration Co-disposal in industrial combustion facilities Pyrolysis/plasma arc

•Environmental performance requirements Destruction 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

Page 10: Management of  ODS Banks/”End of Life” ODS

UNDP Demonstration Destruction Projects

• Original Concept - Demonstration of a range of destruction options

• Cuba: Capture capacity pre-established Cement kiln

• Columbia Incremental capture capability

(consolidation/storage) Export or regional specialty facilities

Page 11: Management of  ODS Banks/”End of Life” ODS

UNDP Demonstration Destruction Projects (2)

• Ghana: Incremental capture capability

(consolidation/storage) Test small local destruction versus export

• Brazil: Link to emerging appliance de-manufacturing

program Utilization of existing HW Mgt infrastructure or/and

or integrated de-manufacturing processing and destruction

Overall Conclusion: Using existing HW infrastructure has significant cost advantage

Page 12: Management of  ODS Banks/”End of Life” ODS

Barriers to EOL ODS Management

Technology/infrastructure/operational barriers relatively minor

Major practical barriers are:• Creditable institutional arrangements for

ownership care and custody• Regulatory controls to stimulate capture of

sufficient quantities to have any impact Emission bans EOL ODS a regulated hazardous waste Enforcement and meaningful penalties

• Financing a high cost of the EOL mgt. process

Page 13: Management of  ODS Banks/”End of Life” ODS

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)

Page 14: Management of  ODS Banks/”End of Life” ODS

Potential Action in the Caribbean Region

• Characterized by: Low volume potential Widely distributed Absence of policy/regulatory/economic drivers Basic 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

Page 15: Management of  ODS Banks/”End of Life” ODS

Conclusions

Globally 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

Page 16: Management of  ODS Banks/”End of Life” ODS

Conclusions (2)

EOL ODS destruction not limited by technology

Limitations are institutional/regulatory/financial

LVC’s need to act collectively

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