Recycle: Low-density polyethylene (LDPE), commonly found in plastic wrapping films for food or dry cleaning, as well as grocery or sandwich bags, is accepted by very few curbside recycling programs. Unfortunately, most plastic bags will end up in the trash. However Whole Foods, Wal-Mart, and Wegman's Food Marts will recycle any plastic bags if you take them to the store. Check the Earth 911 website [1] to see if your municipal recycling center accepts number 4's.
