Production

The manufacture ofPorsche vehicles inafactory
adjacent toaresidential arearequires morethan
mere compliance withalllaws andregulations.
Whether inproduction orrepair, Porsche always
relies onenvironmentally friendlytechnology.
An example ofthis isthe water-based paintused
in our painting installation.
Water-base paintsandnew painting methods re-
duce solvent emissions by70 per cent.
And thewater usedinthe painting installation isre-
circulated. Wastewaterleaves thePorsche facto-
ry only after being appropriately treated.
A waste-management systemhasbeen intro-
duced toreduce theamount ofwaste whilesimul-
taneously increasing therecycling rate.

Environmentally friendlyvehicles

Modern environmental technologyensurescom-
pliance withallemission lawsapplicable world-
wide.

These havethefollowing advantages:

- Rapid operational readinessofthe catalytic
converters ensureslowemissions, evenin
short-trip operation.
- Reliable operation andgood emission control
over along useful life.

Recycling
-for aPorsche, thisisvirtually
an academic question

More thantwo-thirds ofall Porsches everbuiltare
still running.

Just incase recycling isever necessary, we
take thefollowing precautionary measures:

- Identification ofall materials.
- Use ofrecyclable materials.
- Reusable components designedforsimple
removal.
- These reasons resultinafurther increase in
the recycling ratewhich iscurrently 80per
cent.
