You're not totally wrong, but for a few examples:

It takes 4% as much energy to recycle aluminum as it does to make aluminum from ore.

For steel it is 30-40% depending on the type of steel.

Plastic (making new plastic accounts for approx 10% of our oil consumption) is in the 10% range depending on the type.

Yes the trucks that haul those materials pollute, but so do the one hauling the raw materials. The difference is the HUGE energy savings.



Curious if you could cite your stats. I was under the impression that recycling metal was worth it (especially aluminum), but that it was not worth recycling paper or plastic.[/quote]

To answer a couple of questions, here is an article that compares the energy savings of recycling compared to landfilling many materials: http://epa.gov/climatechange/wycd/waste/downloads/Energy%20Savings.pdf

Here are two articles where I got my stats from:

http://www.popularmechanics.com/science/environment/recycling/4291576

Here is a source that the first article references: http://www.recyclemetals.org/about_metal_recycling

Here is an EPA article specific to plastic: http://www.epa.gov/osw/nonhaz/municipal/pubs/ghg/f02023.pdf
