- Hi
-
- I have long wondered about the balance between the good a catalytic
- converter does whilst in use on a car and the damage done to the environment
- as a whole involved in its production in the first place.
- To make a catalytic converter involves the use of very rare and presumably
- hard to get at maetals such as rhodium and platinum and therefore to extract
- them from the rock/ore/whatever must be very energy intensive and must
- surely produce a lot of polution in this way.
- Does anyone have any feelings/figures on the relative balance of good vs.
- bad. One reason this is of interest to me is that a few years back the EEC
- (boo hiss) had to decide between compulsory catalytic converters and lean
- burn technology and went with the c.c. whereas it seemed more sound in the
- long term to opt for lean burn.
-
- Cheers
