230 Car care
Inspect the undercoating and touch up if
necessary. Pay particular attention to the
fenders and wheel housings, which are
exposed to abrasion by flying gravel, etc. If
the composition has worn or flaked off, the
steel must be thoroughly cleaned and dried
before a fresh coat is applied. The cleaning
is best done with a scraper and a steel wire
brush, followed by washing with solvent.
Apply the new coating thinly, otherwise it
may run off or fall off when dry.
Recovery and/or
recycling of automotive
materials
A typical car consists of metals (65–75%),
plastics (10–15%), rubber (5%) and small
quantities of glass, wood, paper and tex-
tiles.
Some of these materials can be recycled,
while others can be recovered in chemical
processes for reuse in new products or as a
source of energy.
While the Saab 9-3 was still at the draw-
ing-board stage, Saab engineers were
giving serious consideration to how the
maximum quantity of materials could be
reclaimed from the car on its eventual
scrapping. To facilitate sorting, plastic parts,
for instance, have been marked to identify
the precise nature of the plastic.
Approximately 90% of the materials in the
car can be recycled or recovered, where
facilities exist.
Before the car is scrapped, all the oils and
other fluids that could pollute the environ-
ment should be recovered from the car. It
may be of interest in this context to learn that
the refrigerant used in the Saab 9-3’s A/C
and ACC systems (R134a) contains neither
CFCs nor any other chlorine compounds
