metal alone, are secondary raw materials, so
they may be taken to an iron foundry for re-
smelting after having removed the contents
(classified in point 3).
2) Electrical components, including the cable and
electronic material (magnetic cards, etc.), fall
within the category of material classified as
being assimilated to urban waste according to
the laws of your local, state, or federal
government, so they may be set aside for
collection by the public waste disposal service;
3) Old mineral and synthetic and/or mixed oils,
emulsified oils and greases are considered
hazardous or special refuse, so they must be
collected, transported and disposed of at a
special waste disposal service.
NOTE: The standards and legislation concerning
refuse is in a constant state of evolution, therefore
is subject to changes. The user must keep
informed of the regulations at the time of disposal
as these may differ from those described above.
