Recycling Automobiles: a Problem of Environment and Resources 91A130

The socio-economic system is coming to the conclusion that the environment will no longer tolerate and absorb all of man's interventions, and that natural resources no longer constitute a cheap and inexhaustible source of wealth.
In this scenario of the limits of nature and ever-increasing environmental costs, we are faced with the problem of recovering and reusing the materials which go into the manufacture of an automobile.
The replacement of metal materials with polymer materials leads to a reduction in the re-usable waste, and to an increase in the amount of waste with no economic value, or even with a negative economic value.
The use of the non-ferrous and non-aluminous materials in an automobile is beyond the capabilities of new techniques for scrapping automobiles, which means that at the end of their lives, the automobiles must be disassembled, sorted on the basis of the constitute materials, recovered and recycled.
This new approach to scrapping automobiles means that we must plan for the recycling of the families of materials used in the manufacture of automobiles, with preference given to those materials which are cheaper and easier to recover and recycle.
An analysis of the impact of the substitution of materials on the recycling of automobiles and a technical and economic comparison between current and future scrapping technologies is the subject of this report
