The Fifteenth Meeting of the Parties decided to request the Technology and Economic Assessment Panel, in its April 2005 report:
(a) to provide updated useful information on the handling and destruction of ozone depleting substance-containing thermal insulation foams including thermal foams situated in buildings, with particular attention to the economic and technological implications;
(b) to clarify the distinction between the destruction efficiency achievable for ozone depleting substances recovered from foams prior to destruction (reconcentrated) and the destruction efficiency achievable for the foams themselves containing ozone-depleting substances (dilute source).
(UNEP/OzL.Pro.15/9, Decision XV/10).
