Figure 1-9 UCM feature <strong>of</strong> hydrocarbon content <strong>of</strong> light shredder waste in GC<br />
The scientific question that needs to address urgently is about the composition <strong>of</strong><br />
the hump. Whether the hump contains only hydrocarbons has remained a matter <strong>of</strong><br />
speculation rather than experimental pro<strong>of</strong> and no detailed information exists on<br />
the actual composition, presumably varying dramatically between samples. If other<br />
non HC components are present the KW 4 does not then determine HCs and<br />
should not be used as legally binding procedure for measuring HC contamination.<br />
The resulting challenge is to develop an alternative method to reliably measure<br />
HCs in shredder waste or any other source <strong>of</strong> heavy long chain HCs.<br />
Resulting from this problem the specific aim <strong>of</strong> the project is to establish the<br />
chemical content <strong>of</strong> the UCM in light shredder waste and once adequately<br />
characterized develop a reliable method for the determination and quantification <strong>of</strong><br />
HCs alternative to KW 4.As well the study aims at evaluating the extent <strong>of</strong> UCM<br />
weathering or biodegradation <strong>of</strong> the waste. The project however seeks to devise<br />
and develop an MS-based methodology capable <strong>of</strong> analysing and characterizing a<br />
complex mixture <strong>of</strong> hydrocarbons within the light shredder waste.<br />
