End-of-Life Measures. The Technology and Economic Assessment Panel (TEAP) of the Montreal Protocol has been actively quantifying and locating banks of ODS in a series of studies responding to decisions of the Parties. The latest of these was Decision XX/7 which initiated the most comprehensive review of banks and potential mitigation options yet. The Task Force convened by the TEAP to complete this work reported in two separate reports: Phase 1 in June 2009 and Phase 2 in October 2009. The second of these reports focused particularly on the quantification of savings that could be achieved, the timing at which recovery and destruction would be required and the cost of so doing. As had been the case in earlier studies, the TEAP Task Force divided the ODS Banks into three major categories of ‘effort’: low, medium and high. Although ‘effort’ is partially a synonym for ‘cost’, this is not completely the case, since there is some adjustment for the fact that the relative costs of some sectors, such as foams, will always be higher than other sectors, such as refrigeration. Rather than having all refrigerant recovery in the ‘low’ category and all foam in the ‘high’ category, there is some offsetting to allow a level of differentiation within each sector. Note that although the emphasis of the research was on reducing ODS emissions, most of the conclusions could also apply to reducing HFC emissions as well. The TEAP analysis also recognized that recovery from densely populated (urban) areas would be easier than from sparsely populated (rural) areas. Its full analysis is summarized in the following Table 4-1: Table 4-1 LEVELS OF EFFORT REQUIRED TO MANAGE ODS BANKS Sector Low Effort Medium Effort High Effort Domestic Refrigeration - Refrigerant DP SP Domestic Refrigeration – Blowing Agent DP SP Commercial Refrigeration - Refrigerant DP SP Commercial Refrigeration – Blowing Agent DP SP Transport Refrigeration - Refrigerant DP/SP Transport Refrigeration – Blowing Agent DP/SP Industrial Refrigeration - Refrigerant DP/SP Stationary Air Conditioning - Refrigerant DP SP Other Stationary Air Conditioning - Refrigerant DP SP Mobile Air Conditioning - Refrigerant SP SP Steel Faced Panels – Blowing Agent DP SP XPS Foams – Blowing Agent DP/SP* PU Boardstock – Blowing Agent DP/SP* PU Spray – Blowing Agent DP*/SP* PU Block - Pipe DP SP PU Block - Slab DP SP Other PU Foams – Blowing Agent DP/SP* Halon – Fire Suppression DP SP DP = Densely Populated Areas SP = Sparsely Populated Areas * = Still technica...
