B.2.2 Material Factor 2
Materials having a higher energy content than Material Factor 1 materials, for instance those containing
plastics
in greater quantities as defined in Figure B1.
Examples:
- wood or metal furniture with plastic seats;
- electrical equipment with plastic parts or packaging;
- electric cables on reels or in cartons;
- synthetic fabrics.
B.2.3 Material factor 3
Materials which are predominantly unexpanded plastic (see Figure B1) or materials of a similar energy
content.
Examples :
- accumulators without electrolyte;
- personal computers;
- unexpended plastic cups and cutlery.
B.2.4 Material factor 4
Materials which are predominantly expanded plastic (more than 40% by volume) or materials of a
similar
energy content (see Figures B1).
