Notes:
(1) All these materials have very negative enviromental effects. Saving of material has a greater positive effect than the choice of certain materials.
(2) These may have a surface treatment of varnish or paint, which causes a higher pollutiuon risk when dumped
(3) Colour pigments are added which have a strong influence on the pollution risk.
