Mmmm, not so much down South. Now I know I'm painting with a broad brush, but most (but not all) of the people I know who recycle here (Atlanta) are originally from the North....although to your point, it is on the increase.
Kind of an offshoot topic, although at its base, it's oil related.....
The company I work for used to lobby like crazy to keep deposit law bills out of legislation, believing that it would adversely affect purchase intent. While we still don't advocate deposit laws, we have invested a significant amount of money in the development of reverse vendors (bottle return machines @ supermarkets) and earmarked an additional $60 million to open the world's largest plastic bottle recycling plant in S. Carolina...which is scheduled to come on line this year and ramp up to full production in 2009. We made a commitment about 10 years ago, at the behest of environmental groups to include 20% recycled PET in our containers (The FDA limits recycled content for some food containers). After making the commitment, we discovered that the supply wasn't there and what supply existed, was being drawn by the carpet industry.
To wrap up this drawn out story, CSR (Corporate Social Responsibilty) is a big buzzword(s) now. Some corporations see it as a PR move, and from a business standpoint, it is. However, with most consumer products companies fighting an unprecedented cost of goods increase over the last two years, CSR is now being looked at for its financial impact to the bottom line. Wal-Mart is actually at the forefront of sustainability, whether it be through recycling or material reduction. Again, the driver is money, but we (society/environment) will benefit.
I now conclude my PSA.
By the way, before I went off on my tangent, I wanted to post this link.
