IC 3. Chemical industry: chemicals used in synthesis<br />

The definition <strong>for</strong> chemicals used in synthesis based on the examples given in the HEDSET is:<br />

chemicals used in synthesis are substances either regulating the chemical reaction process (e.g.<br />

catalysts) or being used as an intermediate (i.e. chemicals that are <strong>for</strong>med <strong>and</strong> can be isolated at<br />

an intermediate step between starting material <strong>and</strong> the final product in a sequence of chemical<br />

processes). The HEDSET includes monomers in intermediates, which is only valid in the release<br />

estimation tables <strong>for</strong> the stage of production. For the processing stage the tables of IC 11<br />

“Polymers industry” are used (see also subparagraph 4.2.5).<br />

Apart from UC = 33 “Intermediates” most chemicals in this IC will have to be classified as UC =<br />

43 “Process regulators” or UC = 55/0 “Others”. Formulation may be applicable <strong>for</strong> some<br />

chemicals, whilst recovery is unlikely.<br />

account of the UC chosen (<strong>for</strong> interpretation of the MC see Table 1):<br />

IC 4. Electrical/electronic industry<br />

In electrical/electronic industry a wide range of products is manufactured. It comprises both the<br />

manufacture of components like resistors, transistors, capacitors, diodes, lamps, etc. <strong>and</strong> the<br />

production of televisions, radios, computers (PC’s as well as mainframes), radar installations,<br />

complete telephone exchanges, etc. In the manufacturing processes constituent processes may<br />

take place. The main constituent processes are electroplating, polymer processing, <strong>and</strong> paint<br />

application. The emissions of substances used in these separate processes are not covered in IC<br />

4, but in the following ICs:<br />

• IC 8. “Metal extraction, refining <strong>and</strong> processing industry”: electroplating <strong>and</strong> other metal<br />

processing (e.g. use of metalworking fluids);<br />

• IC 11. “Polymers industry”: polymer processing (shaping of thermoplastics <strong>and</strong> curing of<br />

prepolymers e.g. <strong>for</strong> the embedding of electronic components);<br />

• IC 14. “Paints, lacquers <strong>and</strong> varnishes industry”: application of coating products by all<br />

means of methods like spraying, curtain coating, etc.<br />

There are no emission scenario <strong>and</strong> use category <strong>documents</strong> <strong>for</strong> IC 4. There are many different<br />

applications, however, in this IC, which may be characteristic <strong>and</strong> specific <strong>for</strong> it, e.g., the
