Does recycling help reduce global warming?

I have always been under the impression that recycling was a solid-waste management issue, and not an energy conservation / CO2 reduction issue. That recycling actually uses more energy (and thereby contributes to global warming) than simply making something from the raw materials.

However, I see so many people that believe recycling will help reduce the threat of global warming. Is this simply a case of mis-information propagated by the media and interest groups, or is there actual scientific fact that supports this belief?

I realize that everyone has an opinion, but I am looking for facts that either support or debunk the notion that recycling will reduce global warming.

P.S. I realize that aluminum recycling actually does conserve energy, but I am talking about the much more widespread recycling of paper and plastic materials.

At present, recycling isn’t going to have much effect on global warming one way or the other. We haven’t yet developed methods to make recycling any more energy efficient than throwing your crap away. (Despite what you’ve been told, recycling is never =less= efficient than throwing stuff away.)

But that’s not the point. The idea of recycling is one of conservation. Anything you throw away will likely remain sitting in the ground for many thousands of years, where it’s of no use to anyone. By recycling it you allow it to be reused many times over. So the point is not being wasteful.

And the more you recycle the faster waste management companies can develop ways to make it more efficient. So it’s a good thing all round.
