I’m a huge fan of going green when it can save you some green, such as when supermarkets reward you (financially) for bringing your own shopping bags. That’s why this new promotion COTTON. FROM BLUE TO GREEN, with Cotton Inc. and The Gap caught my eye: between now and March 14th, you can bring in your old blue jeans to Gap stores for free recycling, and in return you’ll get a 30% off coupon for a new pair of jeans at The Gap. What does Gap do with those jeans? Turn them over to Cotton Inc. to turn those old jeans into blue jean insulation.

Since the program began in 2006, the COTTON. FROM BLUE TO GREEN denim drive has collected more than 14,000 pairs of jeans and has recycled enough denim to create natural cotton fiber insulation for over 540 homes.

When we were shopping for formaldehyde-free insulation last year, we’d considered blue jean insulation, but it was too expensive for our budget. But if you can afford it, I think it’s an awesome option.

And getting money off a new pair of jeans is pretty awesome, too.

Do you think you’ll recycle your old jeans between now and March 14th–for both the green (earth) and green (discount) benefits?
