I'm not a perfect "green" citizen, rather I'm the average consumer who intends to shop with canvas bags, but forgets to ever bring them along.  This results in an inordinate amount of plastic bags tumbling out of my kitchen pantry by the end of the month.

Now, I am able to reuse some of the bags around the house as trash can liners (keep a few in the bottom of your bathroom garbage cans and you'll always have a spare after you pull the full one out on trash day). But I can never use the number I manage to collect in a week even with forgoing a bag at the store when I only have a few items or saying, "No, I don't need a bag for my gallon of milk."

Plastic bags aren't listed as a recyclable through my local garbage collection, so I was at a loss with what to do about my growing bag collection, until a recent stop at Wal-Mart. The retail giant is now a drop off site for recycling plastic bags. The boxes are in the entryway, usually within the first set of doors. If you aren't a Wal-Mart shopper, you can also recycle your bags at area Roundy's stores
